Clean water for Moscow
As one of the oldest water systems in Europe, Moscow’s 100-year-old plus central water
supply and the City of Moscow are faced with the challenge of meeting today’s enormous
water demands. The majority of the water requirements come from the growing population, 11.5 million at present, and the industries in the Moscow area.
validate the performance of the membranes and to
optimize operating conditions. The remaining 110
Aquaflex units containing another 3,300 membrane
modules will be installed in eight phases with completion set for the second quarter of 2012.
To ensure a safe and reliable supply of drinking water,
the City of Moscow added a large-scale drinking water
plant almost a decade ago. With ultrafiltration (UF)
technology at its core, the Drinking Water Plant SouthWest Moscow is one of world’s largest UF plants with a
capacity of 6.6 million gallons per day (250,000 m3/d).
Pentair X-Flow’s UF membranes remove all fine silt and
turbidity (suspended particles) and create a hygienic
barrier for bacteria, viruses, and other micro-organisms. The Aquaflex units combine a vertical configuration with the advantages of an advanced UF module
that uses low energy while providing maximum performance. This allows the system to be designed with
higher flux rates, a reduced footprint, and the flexibility
to treat a broad range of feed water qualities.
In 2010, WTE Wassertechnik GmbH, the German company that designed, constructed and operates the
drinking water plant, was looking for a new UF membrane supplier. Based on a range of selection criteria
Pentair X-Flow’s Aquaflex™ UF membrane modules
were chosen to replace the original ones.
“Pentair X-Flow is delighted to be entrusted with this
project,” said Jürgen von Hollen, Managing Director of
Pentair X-Flow. “This project requires close cooperation
with WTE Wassertechnik GmbH and it gives all involved
great pleasure to see our solution succeed at this strategic drinking water plant that serves Moscow’s population.”
The South-West Moscow project is divided into several
phases as the retrofit takes place during production,
which means that each new unit instantly goes on-line.
In the last quarter of 2010, two Aquaflex units containing 60 Aquaflex membrane modules were installed to

the ability to adapt the membranes to specific applications.
Advantages of the Pentair X-Flow’s HF Nano
membrane include:
Smaller footprint
Reduced energy consumption
Reduced water loss due to higher product recovery
Reduced chemical consumption since no coagulation and/or pH correction is required
Capable of recycling high or low pH solutions currently being discharged
No pre-treatment required
Chlorine and chemical resistance
The HF membranes’ skin is on the inside, thereby applying Pentair X-Flow’s proven in-to-out filtration concept.
Application areas
Due to its unique characteristics, the HF Nano membrane can be applied in many fields where current
technology is insufficient. Different pore sizes and different fiber diameters make it possible to selectively
remove colloidal matter (silica), organics (humics) and
small organics (DOC/TOC), if necessary combined with
direct coagulation.

Pentair X-Flow extends the
range of membrane filtration
products strengthening its water
reuse product portfolio
written by frans knops, erik roesink
Current generation hollow fiber (HF) and spiral wound (SW) membrane modules leave a gap in the current filtration market that needs to
be closed in order to make more water reusable. While existing low pressure HF membrane filtration technologies can filter a wide range of
particles out of a wide range of feed water types, there is still room for improvement and an urgent need for membrane filters with different characteristics. Existing SW nanofiltration (NF) technology requires extensive pre-treatment and is not resistant to oxidative cleaning
substances. Pentair X-Flow’s new HF Nano membranes are specifically designed to fill this gap and extend the range of membrane filtration.
This new type of capillary membranes with NF characteristics opens new horizons and makes substantial amounts of water reusable.
knowhow 2011
Nanotechnology – A quick introduction
Nanofiltration is a pressure-driven membrane process
which, in terms of separation characteristics, lies
between ultrafiltration (UF) and reverse osmosis (RO).
The separation characteristics of NF are dictated both
by size exclusion, like UF, as well as by charge or Donnan
exclusion, like RO. Therefore, the ability to handle elevated solids levels is important as well as correct control of the concentration polarization layer. The pore
size of the NF membrane is characterized by a cut-off
value, expressed in Dalton, that is consistent with the
molecular weight of the smallest molecule that can be
90 percent rejected by the membrane.
Properties of Pentair’s HF Nano
With the new HF Nano capillary membrane, Pentair
X-Flow is the first company that successfully combines
the advantages of both NF and HF technologies. In one
single process step Pentair X-Flow’s HF Nano membranes are capable of removing pollutants impossible to
remove with currently available technologies. The HF
Nano membranes thus offer a leading-edge separation
Removal of colloidal silica is of interest in power plants
or for untreated surface water. Particulate silica (sand
particles) can be removed by conventional pre-treatment and reactive silica (ionized) can be removed by ion
exchange and/or RO. Colloidal or polymerized silica
however can only be partly removed by conventional
treatment methods. HF Nano is a robust membrane that
can offer a true alternative here as it offers the most
reliable protection for boilers and turbines. The silica
removal rate is 10 times better, no coagulant is needed
and the HF Nano membranes can be used early on in the
process as pre-treatment instead of polishing.
are needed and there are no disinfection by-products. It
also offers a low chemical and energy consumption.
Moreover, the wastewater does not need to be neutralized prior to processing. This offers the opportunity for
recycling high or low pH rinse water.
Ultrapure water
In areas where ultrapure water is required, for example
the semiconductor, solar or pharmaceutical industries,
HF Nano membranes can be used for the final polishing
in the ultrapure water loop. The HF Nano membranes
have unique properties, such as shipment without glycerin. This improves the TOC rinse up, thus decreasing
rinsing times. The special construction inside the membrane and the use of customized pressure vessels
allows for operation at elevated pressures, e.g. as final
polishing step downstream of the circulation pumps.
HF Nano technology outlook
During the last several months, Pentair X-Flow has
shipped small scale demonstration HF Nano plants
worldwide. These “quick scan units” are easy to set up
and allow customers to witness performance and to
quickly see results on specific feed water and applications. The first orders for Pentair X-Flow’s HF Nano have
been received for silica removal in boiler feed reference
plants. Currently, research is directed into fine-tuning
the HF Nano membranes for distinct applications with
different characteristics, such as pore size, retention
properties, solids handling ability, and operating pressure. Targets for the near future include designing
membranes for removal of micro-pollutants, such as
endocrine disruptors and reduction of divalent salts. In
the future, new applications such as one-step potable
water production (elimination of micro-pollutants, turbidity and microbiology from surface water), sulfate
removal and the complete elimination of biological
fouling by removing all dissolved organics will be
Organics removal
HF Nano’s organics removal rates offer new perspectives to produce potable water from surface water and
to treat wastewater. For the purification of surface
water, HF Nano offers a one-step treatment to remove
humic and fulvic acids without sludge production. No
coagulants are needed, the treatment requires few
cleaning chemicals, water recovery is high, and water
produced can be approved for potable water use. As the
HF Nano membrane allows for selective removal of
color, it is especially fit for the treatment of wastewater, e.g. in the textile or food industries. During the filtration process, no sludge is produced, no coagulants

Hybrid Deionization Technology
Pentair Filtrix introduces
the sterile Medical ShowerFilter
Targeting a new ‘infection control’ segment
written by frank van heusden
Water purification using membrane technology has been proven reliable over the years in
applications such as large drinking water installations. For some time now, membrane
technology has also been applied in point-of-use (POU) products and is a successful
weapon in the fight against Legionnaires’ disease. While membrane technology can serve
as a temporary solution to combat Legionella contamination, it is also ideally suited as a
permanent answer to solve the challenge of water purification in hospitals.
Regulations and risk management
With the increasing attention for waterborne infections,
governmental regulations are getting stricter. At the
same time organizations or departments that are
responsible for infection control are using more and
more advanced risk management models. In order to
prioritize their risk response activities, they usually
quantify the probability and the severity of the consequences of identified risks.
Medical filters for the highest risk level
The highest risk levels appear in the healthcare market.
Examples of high-risk organizations are hospitals, home
care organizations and nursing homes. Patient safety is
of vital importance, especially in sterile areas such as
hematology, oncology, burn units and intensive care
units. One of the main concerns is the risk of bacterial
infections, which can be caused by microbiologically
contaminated shower and tap water. Waterborne pathogens can accumulate in biofilm located within the plumb-

It has taken years of market research and extensive testing before being able
to validate a brand new concept for residential and light commercial applications that would treat water in a brand new way. This new process of treating
water is called Hybrid Deionization technology, which uses 90 percent each of
the capabilities of a standard water softening system and a reverse osmosis
Shower filters for the medium risk level
Photo: Astrid Paulisch
Pentair Filtrix products are applied in a variety of markets with the common factor of ‘health protection’. The
applications that are developed within the area of
‘drinking water solutions’ are mainly targeting the OEM
market. And for the other key area ‘infection control’,
Pentair Filtrix develops complete ready-to-use systems
for POU as well as for point-of-entry (POE) purposes.
Over the last few years, there has been an increasing tendency
to consider the environment in its whole and to reduce the
footprint. Because Pentair Residential Filtration focuses on
sustainable solutions, this created an opportunity for innovation.
Biofilm (red) retained by membrane (green)
ing system, even if the water is disinfected at the pointof-entry. The pathogens can be transmitted to patients
when the water is used for their care.
A new product meeting specific needs
For these extremely high-risk areas Pentair Filtrix
developed a Medical ShowerFilter with a full CE 1S (sterile) validation. The gamma radiation treatment, the
sterile blister packaging and the additional anti-microbial layer on the filter head assure the safety of extremely vulnerable patients.
In situations where organizations are dealing with highlevel risk areas that do not require sterile spaces –
home care organizations and elderly homes – the nonsterile version of the Medical ShowerFilter can provide
permanent safety for patients.
For organizations such as hotels, sport facilities, wellness and spa centers that face a medium-risk level the
most harmful water bacteria is Legionella. This waterborne pathogen can cause the dangerous Legionnaires’
disease. The most common route of infection is inhalation of airborne droplets containing the Legionella bacteria from outlet points of hot water installations, such
as showers.
For the safety of their guests or visitors, these medium
risk level organizations check their water system on a
regular basis for the presence of Legionella. If Legionella
is found in the water it can be eliminated from the
water system via different water treatment methods.
But, until the water is tested again in order to see if the
treatment was effective, the water is not 100 percent
safe. During this period, temporarily remedy can be
provided with the Pentair Filtrix ShowerFilter. This
unique ShowerFilter looks and handles like any familiar
handheld shower and will not make the guests unnecessarily anxious or suspicious. But at the same time it
holds a replaceable filter cartridge that contains microfiltration membranes, which effectively retain any
Legionella bacteria present in the water.
With this clearly balanced product offering Pentair
Filtrix covers the three main segments within the infection control market – health care/sterile areas, health
care/non-sterile areas and hospitality.
Using fuel cells and super capacitor capabilities, this unit will be the first device
providing simultaneously an all-in-one
water treatment process : softened water
and “bottle-quality” drinking water
throughout the home, without the use of
salt and consumable membranes.
This will not only provide a new level of
convenience to the homeowner but will
also contribute to a greener planet as the
Hybrid Deionizer will also reduce the need
for bottled water by providing “bottle quality” water to every tap in the house.
Furthermore, unlike traditional softening
units which often require frequent salt
deliveries and filter changes, it will only
need a single annual cleaning to restore
peak performance.
With a touch screen interface it will allow
water professionals and home owners alike
to easily monitor, diagnose and adjust the
system. Consumers will have the ability to
fine tune water to their particular taste
while using the system’s intelligence.
Less waste, softened and pure water,
financial savings, are strong key selling
points, which the Hybrid Deionizer can
claim thanks to its technological leap forward.
9100TS – Twin Tank Sensor
Pentair Residential Filtration has developed a new solution for
those wishing to go one step further into sustainability by reducing
the amount of water and salt used in each regeneration.
This solution is the new 9100TS (Twin Sensor), which is able to save regenerant and
less water (up to -15 percent) and deliver conditioning performance that is completely
How does it practically work ? Twenty four hours a day, a microcomputer designed to
respond to changes in system status detects fluctuating water conditions thanks to a
pair of non-corrosive gold-plated electronic sensor probes and triggers an instant
response to deliver two big benefits: firstly a consistent quality, thanks to those sensors
which signal a drop below optimum condition, so water never passes through untreated. Secondly a 100 percent efficiency as it is able to use all of its treatment capacity
before regenerating, saving both water and regenerant.
Those sensors are always on guard against changes in the water conditions, responding
only when the time is right to protect water quality and conserve valuable resources.
Besides, thanks to its twin tanks the system switches to a fresh tank that is always
standing by, changing from one tank to the other so quickly that the homeowners
won’t even know a changeover is taking place.
The tank conditioning capacity is therefore 100 percent used, meaning less regeneration, less water sent to the waste, less salt used, making the 9100TS one of the most
efficient softeners from the market.

In 2005, Hurricane Katrina, the costliest
natural disaster in U.S. history as well as one
of the strongest U.S. storms on record,
caused widespread devastation along the
central Gulf Coast states. Damage was estimated at $81 billion and sadly 1,836 people
died during the hurricane and subsequent
flooding. New Orleans was particularly hard

storm’s impact flooding 80 percent of the
city with 20 feet (~ 6 m) of water. Today,
350 miles (~ 563 km) of levees, floodwalls,

the effects of future severe storms. This
system, known as the Army Corps of
Engineers’ (ACOE) Gulf Intracoastal
Waterway West Closure Complex (GIWW
WCC), markedly improves the patchwork of
levees and walls that were breached during
Hurricane Katrina.
The system will minimize the risk of storm surges
across the west bank area near New Orleans and is a
major component of the Hurricane and Storm Damage

surge risk to residences and businesses in the Orleans,
Jefferson and Plaquemines parishes on the west bank

The Challenge: Design, Develop, Deliver
How It Works
Pentair first started work on pump stations in New
Orleans after the ACOE awarded the company the 17th
Canal Street project. In just six months, Pentair Fairbanks
Morse delivered 11 pumps weighing 85,000 pounds
(~ 38,500 kg) each to the 17th Street Canal in 2007.
With construction of the WCC, located approximately
one mile south of the confluence of the Harvey and
Algiers canals on the Gulf Intracoastal Waterway, the
ACOE hopes to prevent storm surges from backing up
into those canals via the closure gate. Once the gate is
closed, the surge is blocked; however, water is still
collected, which makes it necessary to pump water
past the gate. The WCC pumping station removes
that excess water. Each pump moves 800,000 gallons
(~ 3,000 m3) of water per minute pushing it past the
gate and away from the surrounding parishes to protect
homes, businesses and most importantly people.
The experience on the 17th Street Canal project allowed
engineers at Pentair Fairbanks Morse to quickly run
tests necessary to develop the 140-inch Vertical
Propeller Pumps for the pumping station at the West
Closure Complex. Pentair Fairbanks Morse designed,
developed and delivered 11 20,000 cubic feet per second (566 m3/s) pumps for flood protection to the WCC
in June 2011 – in time to protect New Orleans ahead of

reverse osmosis system (SWRO) is located in the Caofeidian Industrial Zone near the
city of Tangshan and part of a large-scale governmental construction project.
Seawater Reverse Osmosis is a leading process for
desalination. While the characteristics of RO membranes are ideal for removing the salt, they also remove
minerals from the water. As a result, after RO membrane treatment the water is not suitable for consumption. A post-treatment to re-mineralize the water is
The Pentair Haffmans’ CO2 dosing and injection system
installed at Caofeidian, 136 miles (~ 220 km) from

adds CO2 to the permeate flow during post treatment.
To make RO water drinkable, water leaving the RO
membranes is carbonized so that minerals can be dissolved at the calcite filters. Pentair Haffmans’ Carbo
Controller side stream carbonation system automatically and accurately doses the CO2 into the water to
decrease the pH value. This allows the calcium ion to

The Dutch Water Board Regge and Dinkel
and Pentair X-Flow have successfully started
the first Pentair Airlift™ MBR Megablock at
the wastewater treatment plant (WWTP)
Glanerbrug. An upgrade of the existing
conventional installation was necessary in
order to meet new capacity requirements
and comply with the European Water
Framework Directive (WFD).
A six month test period was launched in May during
which Pentair is operating the upgraded wastewater
treatment plant. The objective is to demonstrate that
this new concept is technically the most efficient and
cost-effective solution for upgrading existing WWTP’s.
In the next phase, planned to start in the fourth quarter
of 2011, the capacity will be doubled allowing for more
wastewater to be reused.
The Pentair AirliftTM MBR Megablock system at Glanerbrug handles 75 percent of the sludge/water separation
by treating 79,250 gallons per hour (300 m³/h) with
membranes. This results in a significant improvement
of the water quality, especially during dry weather
conditions, an effluent without suspended solids, and
an absolute barrier for bacteria and viruses. This project
is co-financed by the Water Framework Directive
Innovation Program executed by AgentschapNL by
order of the Dutch Ministry of Infrastructure and The
Pump developed
for Megablock
The Megablock is an integrated solution showcasing
cross business know-how and product innovations.
These types of integrated solutions allow us to deliver
competitive advantage and make it difficult for competitors to follow our lead. Furthermore our customers
are receiving the best possible packaged solution knowing that all components work and will be serviced by
one company – Pentair.
A clean solution for wastewater treatment
Advantages of the Pentair AirliftTM MBR Megablock:
1. Lowest energy consumption
The Megablock is able to follow daily wastewater flow fluctuations and switch off units that
are not needed. This reduces the energy consumption by 25 to 50 percent compared to
submerged systems. This cannot be done with submerged systems as the sludge will settle
to the bottom of the tank if the aeration is switched off.
2. Clean solution
As a dry solution (sidestream) all modules can be accessed individually. There is no need
for manual operation as the cleaning of the membranes is entirely automatic without
operator intervention.
During the development of the Megablock, Pentair
Nijhuis was involved in optimizing the hydraulic
aspects of the design. In the design phase,
detailed CFD analyses were performed
to minimize energy consumption
and keeping the filter load as
even as possible (mixing).
CFD, an acronym for
Dynamics, is used for
making calculations to
analyze fluid flows and is
routinely applied during the
design of rotating machinery.
Pentair Nijhuis has considerable
expertise in this field.
Pentair Nijhuis developed in-line pumps customized for the Megablock
application. In addition to minimizing energy consumption, also minimizing floor space formed a main objective in this development process.
Axial propeller pumps were the best choice for the capacities and
pressure heads required. The pumps developed provide a unique and
integrated solution for this specific application.
3. Minimized footprint
The ultrafiltration (UF) unit is built in a new skid design, with the modules grouped
together. This results in a minimized footprint.
4.Internal circulation/minimized feed flows
The specially developed recirculation loop reduces the feed flow to and from the UF unit,
which results in smaller pipe dimensions. The highly efficient internal recirculation pump,
designed by Pentair Nijhuis, guarantees the right velocities in the individual membrane
5. Modular system
The Megablock unit is based on modular segments and is easy to expand. The Megablock
can have one to six modular segments each with 36 membrane modules and a nominal
capacity of 20,000 gallons per hour (75 m3/h).
6. Unique integrity detecting solution
In case of an incident the integrity of the modules can be individually checked without
dissembling the whole unit. This is unique for UF membrane units in wastewater treatment.
7. Quick and easy connections
The newly developed connections result in a faster total construction time and significantly reduce the time required for unit built-up and membrane loading.

Overhaul Biesbosch pumps
for Evides Waterbedrijf
written by inge sluijter
Recently, Pentair Nijhuis overhauled the exchangeable pump set of Evides Waterbedrijf, a
water company in the Netherlands. These pumps are used by Evides to move untreated
surface water from the Meuse River to reservoirs in the Biesbosch. Evides supplies citizens
of southwestern Netherlands with drinking water and large industrial companies with
industrial water. In addition, Evides is active in wastewater treatment.
The pumps are in constant operation and thus need to
be overhauled every five to six years. Since it is crucial
to maintain the buffer store level in the reservoirs to
ensure uninterrupted drinking water production, the
pumps cannot be shut down for extended periods.
Therefore, Evides Waterbedrijf has an exchangeable
pump set that acts as a back-up to the active pumps.
The Services department of Pentair Nijhuis overhauled
the exchangeable pump set, removed the active pumps
from the cellar in situ, and installed the overhauled
pumps. It concerned two large pumps, 18.7 feet (5.7
meters) long and 6 feet (1.85 meters) in diameter with
a capacity of 1056 gallons per second (4 m3/s) each. The
pumps were serviced at Nijhuis Services in Beverwijk,
the Netherlands. In addition, several technical improvements were made to the pumps. The project
was completed with minimal pump downtime, ensuring Evides could maintain a continuous water supply to

Get more out of your waste
with Anaerobic MBR
written by janna dirks
written by toine toten
Handling and disposing of waste streams is a basic part of the manufacturing processes, but can be a unique challenge for many dairy,
food and beverage plants. Often these production processes yield high-strength waste streams that are costly to treat and dispose of
using traditional treatment methods. Pentair X-Flow’s technologies including the Crossflow Membrane BioReactor (MBR) and expertise in
wastewater applications are applied to the anaerobic treatment process resulting in a system that produces more biogas in a smaller
footprint with lower operating costs.
Pentair Haffmans recently supplied a biogas upgrading installation to the Hoogheemraadschap Hollands Noorderkwartier (HHNK) wastewater treatment plant in Beverwijk, the
Netherlands. Here, biogas generated from sludge is upgraded to biomethane and carbon
dioxide (CO2), thus producing two valuable products.
High loads are good
Though waste streams loaded with high levels of
organic matter are challenging to treat, the anaerobic
digestion process feeds off the high-strength waste.
“Membrane bioreactors are not new to the food industry, nor are the membrane separation processes in
wastewater treatment,” said Pentair X-Flow’s Product
Manager Michiel Koelen. “But the concept of combining
an anaerobic process with membrane separation is
new. It generates much more energy from wastewater
while producing high-quality effluent.”
The traditional anaerobic process offers a partial solution for high-strength waste, but because these systems have a maximum efficiency of 85 percent, additional effluent treatment is required and biogas production is limited.
“Conventional anaerobic processes require a final aerobic step to treat the remaining 15 percent of the effluent
that wasn’t digested,” said Pentair X-Flow’s Area Sales
Manager Thijs Wolbrink. “This increases the total treatment plant’s footprint and operating costs. The addition
knowhow 2011
of Pentair X-Flow’s membranes increases the yield of the
anaerobic process, resulting in increased biogas production and it improves the quality of the wastewater effluent to a standard comparable to aerobic plants as we can
convert almost all organic substance to biogas.”
The process
The anaerobic process using Pentair’s X-Flow membranes is typically 99 percent efficient and the effluent
can be easily brought to discharge water standard quality or further treated for reuse. The process begins when
the wastewater enters the bioreactor via a heat exchanger. Micronutrients are added and the waste ferments,
which produces biogas and gradually the organic matter
is transferred into biogas. Using Pentair X-Flow’s
Anaerobic MBR the liquid in the fermenter is cycled
through the membrane separation plant, which assures
that all the sludge remains in the reactor, which increases the efficiency of the system.
High gas yield equals cost effectiveness
As almost all organic matter in the fermenter is turned
into gas – methane and carbon dioxide – the biogas
yield is higher than in comparable processes. Energy
recovery may be 15 to 20 percent higher than in conventional anaerobic wastewater treatment. Moreover,
the costs for wastewater discharge tend to be zero
given the “purity” of the effluent. “The system pays off
mainly from the increased yield of fermenter gas and in
addition to that there is a significant reduction of the
post-treatment costs” Wolbrink said. “The gas can be
used in the steam boiler or it can be introduced into the
local grid after purification.”
In the wastewater treatment process water and sludge
are separated. Biogas can be produced from the sludge
that remains after the separation. In Beverwijk 70.6 million cubic feet (2,000,000 m3) of biogas are generated
per year in three fermenters. Biogas can only be used
efficiently when it is deployed near the place of its generation, for example in combined heat and power units. A
better alternative is to upgrade the biogas to biomethane,
which can be fed into the natural gas grid and thus contributes to an even more promising energy mix.
A model for future projects
In conjunction with partner Biothane, Pentair X-Flow’s
Anaerobic MBR is installed in anaerobic systems in the
United States and Poland, which is currently under construction. In addition, several pilot tests are being executed in various market areas worldwide.
HHNK selected Pentair Haffmans’ biogas upgrading
system to replace the existing one. Pentair Haffmans
designed a compact solution, housed in two preassembled 40-foot containers that were placed at
HHNK near the biogas fermenters. The system is scheduled to go into operation before the end of the year.
HHNK and Pentair Haffmans calculated that after startup more than 42.4 million cubic feet (1,200,000 m3) of
biomethane can be produced per year at Beverwijk.
This is enough to supply 700 households for a year.
Because the biomethane has the same specifications as
natural gas it can be fed into the national gas grid. The
Dutch company Biogast provided its Bio2Net feed-in
station to connect the system to the grid and guided the
project through all procedures and permits.
“Beverwijk started as a pilot project and is now developing into a profitable installation, which is financially selfsufficient, even without governmental subsidies,” said
Fred Duineveld, head of HHNK’s Beverwijk Beheer
Waterketen division. “Thus, it has the potential to serve
as a model for additional projects and to promote the
benefits of biogas upgrading in the Netherlands and
Pentair Haffmans state-of-the-art biogas upgrading
technology offers two additional economic benefits,
which are unique in the industry. The technique used by
Pentair Haffmans makes it possible to recover 100 percent of the biomethane, so the environmentally harmful
‘methane slip’ that usually occurs when other upgrading
techniques are used, is completely eliminated.
Besides ecological benefits, this also means that more
biomethane can be fed into the grid. In addition, Pentair
Haffmans’ biogas upgrading installation allows the customer to recover the CO2 by-product. This results in an
extra source of income as the recovered CO2 is foodgrade quality and can be sold for use in greenhouses or
in food and beverage applications. (See additional text

Biomethane for the tank
Not all of the biomethane produced at Beverwijk is fed into the grid. Part of it
is used to fuel HHNK’s car pool. The company placed a filling station on its
premises, next to the upgrading system. Here the biomethane is pressurized so
that it can be used to fill the cars’ tanks, thus providing a cost-effective alternative to ordinary fuel. Currently, HHNK has 19 biomethane-fueled cars.
According to Duineveld, HHNK plans to add more than 50 biomethane-fueled
cars in the coming years. At that point, seven percent of the biomethane produced at Beverwijk will be used to fuel cars. Meanwhile, other water authorities in the Netherlands have shown interest in running their cars with the
biomethane produced at Beverwijk.
The Beverwijk installation is a promising example for a flexible, sustainable and
efficient use of multiple types of resources. “This project will gain a lot of
attention as it shows the great potential of sustainable energies and a variety
of options of how to deploy them in the best possible ways,” Duineveld concluded.

The new Waterfalls range from Pentair Residential Filtration consists of three different types of softeners, which are completely
equipped and ready to be installed. Assembled from Pentair
components, each softener was made in Europe and developed
for customers who wish to promote a fully packaged solution.
Aimed at supplying high quality water across the residential environment, each
Waterfalls softener guarantees that every end user will benefit from all advantages
that only a softener can provide, which include an unrestricted water flow from a free

formation of scale and a reduction of about 50 percent of soap, cleaning chemicals
and detergents usage.
Unique biogas upgrading technology
Biogas is a general term for gas produced from anaerobic fermentation and
primarily consists of a mixture of methane (CH4) and carbon dioxide (CO2).
Pentair Haffmans’ biogas upgrading technology makes it possible to recover
100 percent of the CH4, so the environmentally harmful ‘methane slip’ that
usually occurs during this process is completely eliminated. This results in a
higher CH4 yield and no emission of the harmful CH4 greenhouse gas. In addition, the CO2 by-product is recovered and can be sold as a valuable product.
In Pentair Haffmans’ process, after the ammonia is washed out of the biogas,
the biogas is cleaned by a Norit activated carbon filter and then the cleaned
biogas flows through a membrane installation where it is separated into CH4rich and CO2-rich gases.
The CO2-rich gas is then fed to the CO2 recovery system. Here, it is liquefied and
the liquid CO2 flows through a stripper column where the remaining CH4 is
removed and fed back to the membrane unit. The liquid CO2 flows out of the
stripper and can then be stored in a buffer tank. Pentair Haffmans’ long-term
experience in CO2 purification and liquefaction systems guarantees the quality
of this process.

Pentair Industrial Driflex –
An innovative, high capacity
oil conditioning system
written by lisa stich
The Pentair Industrial® team partnered with
Turbo Filtration Corporation (Mobile, Ala., USA)
to replace its traditional, vacuum dehydration systems with the state-of-the-art
Driflex™ Oil Conditioning System. Turbo
Filtration is a service provider for oil conditioning in many industries, including power
plants and industrial sites. The partnership
between the two companies has proved to
be a win-win for both sides.
Almost all electrical power on Earth is produced with a
turbine of some type. A turbine is a rotary engine that
extracts energy from a fluid flow and converts it into
useful work. Turbines operate at a high speed and a key
component of these systems are rolling elements and
pressure surfaces which rely on a clean layer of oil to
separate them. Oil quality deteriorates throughout use
due to both particulate and moisture contamination.
Reduced oil quality exhibits itself in many forms including rust, corrosion, oxidation, additive depletion,
changes in viscosity and more. All of these negatively
affect machinery efficiency and component life so oil
quality must be addressed through effective oil conditioning programs.
Turbo Filtration Corporation (TFC) provides lube oil system cleaning services to the power generation and
other industrial markets. They have a long history and
outstanding reputation in the industry. By helping to
maintain absolute system oil cleanliness, TFC assists its
customers in maximizing equipment life, minimizing
system downtime and optimizing profitability.
Traditionally, TFC and the industry as a whole have
employed vacuum dehydrator oil purification systems
for oil remediation and ongoing conditioning. This
method essentially uses both heat and pressure to
vaporize water, evaporating it into the air. A significant
disadvantage to vacuum dehydration is that it requires
the oil to be heated. This can damage oil additives and
cause process-contaminating breakdown products.
Some vacuum dehydrators also contain filtration to
remove particulate contaminants. Others do not and
thus particulates remain in the oil after dehydration.
The complexity and total cost to operate vacuum dehydrators can make outright purchase and permanent
installation prohibitive for some customers. Companies
may instead rent the units from firms such as TFC, or
hire firms like TFC to periodically bring in a skid-based
system and operator to perform a cleaning.
Alternatively, the Pentair Industrial Driflex Oil
Conditioning System utilizes particulate filtration and
high efficiency membranes to thoroughly remove both
solid contaminants as well as free, emulsified and
dissolved water from the lubricant. The Driflex
system has numerous advantages over vacuum
dehydration methods, including:
It offers customers the ability to achieve and maintain the best oil quality possible on a
continuous basis, on their own remediation schedule or in response to an upset.
It is compact and cost-effective enough to install permanently for dedicated use on a particular reservoir, moved for periodic use
on reservoirs throughout a facility, or work as part of a third party service agent’s standard rental program.
It does not require dedicated manpower to operate and a fully unattended operator
version is available.
It is conveniently sized and easy to install and maintain – no moving parts beyond its pump and no flow or level controls to continually adjust.
It is available in flow rates up to 32 gpm to serve a wide variety of applications within a power plant or industrial site.
With its simple and reliable operation, the Driflex Oil
Conditioning System is designed to enhance equipment
performance, protect valuable machinery and optimize
service life.

written by Ryan Bennett
In today’s oil refineries, water is prevalent throughout the complex process of turning crude oil into gasoline, diesel and jet fuels. Whether
it is early in the process as wash water introduced in a desalter or later as a by product of hydro-treatment in diesel production, water is
integral to refining fluid process streams. A by-product of these efforts is sour water or waste water contaminated with hydrogen sulfide
and ammonia. Before it can be reused elsewhere in the plant or released safely into the environment, sour water must be treated to
reduce contaminants. This is done by diverting sour water from its current process stream and sending it to a sour water stripper where
the pollutants are removed or “stripped off”.
written by jose guillen
In the past, a pool was a blemish on an otherwise green home. The water waste, energy
consuming pool pump, and chemical usage ran in direct opposition to the tenets of
sustainability. But with recently adopted technology and a pool industry ready to move
toward more holistic sustainable methods, it is possible for the pool buyers to own a
restful water retreat without the environmental guilt.
The implications of a sustainable pool industry are
huge. According to the Natural Resources Defense
Council (NRDC) in its report, “Synergies in Swimming
Pool Efficiency”, in 2010 there were 4.5 million inground pools in US, which use $1.1 to $1.6 billion of
energy per year.
Pentair Water Pool & Spa is making a strong commitment to develop the most environmentally responsible
products available to pool users. The Eco Select™ brand
is the cornerstone of Pentair Water Pool & Spa’s green
program aimed at meeting the needs of a growing
number of pool owners – simultaneously saving money
while limiting their environmental impact. Pentair
Water Pool & Spa’s Eco Select™ brand identifies its most
eco-friendly products that contribute to a more environmentally responsible equipment system.
Eco Select IntelliFlo® Pumps
The typical pool pump used today is single-speed.
Unfortunately, it runs at the same tempo even when it’s
not necessary – resulting in wasted energy and greater
noise. With this in mind, Pentair Water Pool & Spa
developed the Eco Select IntelliFlo® variable-speed
pump. At the US Las Vegas IBS Show in January 2010, an
Eco Select 180 watt IntelliFlo® pump demonstrated
annual energy savings of US$ 1,100 versus a traditional
1.9 kW single-speed pump.
The NRDC estimates that in a community with a fourmonth pool season, upgrading from a single-speed to a
variable-speed pump can save the average homeowner
$350 a year. The organization conducted a study on
Pentair’s Eco Select IntelliFlo® variable speed pump and
noted that the system reduces energy use by up to 90
knowhow 2011
percent. Pentair Pool & Spa reports customer savings as
high as US$ 1,360 annually. Savings can be further
improved when larger, straighter pipes; sweep elbows;
lower pressure backwash valves and oversized filters
are used.
Skip Phillips, owner of US based Questar Pools and Spas,
was an early adopter of variable speed pool pumps and
calls them a success. “My pool has filtration, a 14 kW PV
system, and 1/2 horsepower pump. Everyone said I
would need more power to make it work,” he says.
“The variable frequency keeps the operating costs
down. You’re talking about an eight-hour turnover
where the equivalent water is filtered and then it’s
stagnant for 16 hours. With in-line sanitation and low
chemicals and the variable speed pump, you can run at
a low flow rate for less money.”
In addition to the Eco Select IntelliFlo® variable speed
pump, the Pentair Water Pool & Spa suite of environmentally friendly technologies includes the Eco Select
IntelliBrite LED lighting system and the Eco Select
IntelliPool™ and IntelliTouch® automation systems that
automatically limit the operation of pool equipment to
lower cost energy usage or “off-peak” times-of-day.

HRT™ hydrocarbon separator
(4) Recovered Hydrocarbon/Organics
Sour Water Strippers frequently encounter heavy
hydrocarbon or oil contamination from the incoming
sour water feed. Oil emulsion in the sour water feed is
known to cause instability within the sour water stripper and downstream sulfur recovery units (SRU) which
recover elemental sulfur from gaseous hydrogen sulfide. This instability can result in shutdowns, furnace
failures and sulfur emissions. Most refineries seek to
mitigate hydrocarbon ingress into the sour water stripper and downstream SRU through pretreatment with
conventional flash drums and large residence time
Pentair Porous Media’s HRT™ is an innovative hydrocarbon removal process that serves as an alternative to
conventional sour water stripper pretreatment technology. The HRT™ process couples Pentair Porous Media’s
optimized element technology for solids removal with
high performance hydrocarbon separation techniques.
Where conventional approaches to hydrocarbon
removal such as flash tanks and residence time separators have proved largely ineffective, the HRT™ process
creates a balanced system that effectively addresses
hydrocarbon and particle contaminants and allows the
refinery operator to achieve both optimal process stability and environmental compliance. In short, effective
contamination control results in effective process and
environmental controls.
A U.S. refinery was experiencing high change out
rates on their pre-treatment particulate filters
and liquid separator elements prior to the sour
water stripper. It was initially thought that the
high contaminant loading was due to start-up of
a new SRU downstream in the process. The high
rate of fouling continued for several months
with particulate element change outs varying
from once a day to upwards of several times per
day and liquid separator element change out
occurring every three to seven days.
By moving to the HRT™ hydrocarbon removal
process, the plant was able to significantly
reduce the operational cost of their sour water
stripper pretreatment process. Prior to converting to the HRT™ hydrocarbon removal process,
the plant was predicted to spend $250,000
annually in pretreatment. After upgrading to
HRT™ the overall operating cost of pretreatment
was less than $75,000 annually. The refinery
benefitted from superior pretreatment while
simultaneously reducing operating costs and
increasing throughput downstream.

The buffer production is installed in a technical area,
where all modules needing maintenance are located.
This technical area is hermetically sealed from the
actual production area and is built as a class C clean
room. The process vessels are installed as part of this
clean room wall so that related equipment can be operated from the production area.
Mobile container as “Stand alone“ process plant
Automatic buffer production
The largest part of the project was the automatic buffer
production. The unit consists of three buffer preparation containers with volumes of 528, 264 and 132 gallons (2,000, 1,000 and 500 l). In addition, there is a
buffer storage container with 528 gallons (2,000 l) and
a caustic soda recipient vessel with a volume of 264
gallons (1,000 l). This recipient vessel is supplied with a
caustic soda container station fitted with a dosing
pump controlled by conductivity. The hydrochloric acid
station is also equipped with a membrane dosing system. These pumps allow single stroke metering so that
dosing is accurate to 10 ml and the pH-value of the buffer can be adjusted very accurately in small steps.
During production the operator first selects, via the
touch panel, the formula for preparing the buffer. The
allocated water quantity is then fed into the preparation
container. The operator can add salts by hand, possibly
followed by a stirring step or by bringing the preparation to the right temperature. The pH-measuring system monitors the pH-value of the water solution and
controls the addition of base or acid via this parameter,
depending if an alkaline or acidic buffer has to be prepared. The three preparation containers can be released
The mobile containers operate as an independent process plant to be filled with the starting products and to
be connected to the chromatographs or filter units by
hoses. They serve as product storage and transport
container as well as buffer recipient containers.
The mobile containers have capacities between 13 and
80 gallons (50 – 300 l) and are installed on a mobile
frame with fixed pipes. This design allows several process variations. They are pressure and vacuum resistant, fitted with a double shell and can be cooled and
heated. They are fitted with magnet stirrers and have a
number of connections for compressed air, sterile air
and product feed.
Central for the operation of the mobile units are five
distribution panels. All panels are equipped with connections for Water For Injection (WFI), pure steam and a

included. Drains for the product with conductivity and
temperature control were provided. A heating and cooling system with each panel allows the mobile containers’

connected to the CIP via a distribution panel. Cleaning is
automatically carried out according to stored programs.
Both circuits can be cooled by heat exchangers, from a
circulating temperature of 176 - 181 degrees Fahrenheit
(80 to 83 degrees Celsius), to the desired application

installed later at the facility. All piping in contact with
product was recorded, marked and every relevant
welding parameter was documented by the assembly
personnel. About 10 percent of the welds have been
checked by endoscope. All other important factors, like
measuring systems or sanitizing, have also been explicitly qualified. In this way, CSL Behring was not only
given an extremely modern plant, but also “reliable”
process documentation for the important upcoming
qualifying audit.
WSO is used as the primary cleaning medium for prerinsing and the chemical make-up water. The caustic
soda solution concentrate is metered from a base station up to a specified conductivity. The temperature of
the cleaning media can be set and controlled using the
integrated heat exchanger.
The pre-rinse water flow is directed through the mobile
container. The specified rinsing water volume is the
control parameter of the cleaning duration. The prerinse water is routed to drain, however the chemical
wash is circulated. The final rinse is carried out directly
from the hot WFI network through the CIP plant and
distribution panel to the mobile container.
The CIP offers the possibility to sanitize itself via a very
pure steam connection. In addition, there is a pure
sanitizing distribution panel in a neighboring room to
which a mobile container can be connected and a sanitizing program can be carried out.

The best choice for today’s brewer
written by mark mol
Beer filtration and stabilization are the final steps in the brewing
process before the beer is stored in the bright beer tanks prior to
packaging. After this filtration step brewers must be absolutely
sure that the beer tastes fresh and is free of yeast and turbidity.
For this, Pentair’s third generation Beer Membrane Filtration (BMF)
system, the BMF-18, is the best choice to assure the beer quality
and to offer major advantages for sustainability and flexibility
compared to traditional filtration methods.
Beer Membrane Filtration vs. Diatomaceous Earth Filtration
BMF uses membranes instead of a diatomaceous earth (DE) to remove unwanted
turbidity from the beer. This provides immediate environmental benefits as the DE
can only be used once and then must be disposed, whereas membranes are used for
several years. In addition, the health and safety risks caused by DE are eliminated.
With BMF, brewers experience a consistent beer quality during a filtration run and
produce a beer with longer shelf life and better taste stability. BMF also brings flexibility into the production as the system guarantees a continuous operation as well as
fast and easy brand changes.
Innovations of the BMF-18
The BMF system incorporates two fundamental sustainability principles as it requires
less stainless steel while providing a higher capacity and doesn’t use disposable or
non-recyclable resources.
knowhow 2011
After it was first introduced in 2009, the BMF-18 continued to undergo development.
“Product improvement is on-going,” said Pentair’s Dick Meijer. “We are constantly
working to improve efficiency for our customers and at the same time contribute to
a more sustainable environment.”
In some breweries, small amounts of barley are
already added to the malt prior to mashing. The main
driving forces for this are lower costs and carbon
footprint, and the better availability of barley. The
amount of barley that can be added is limited by the
reduced enzymatic activity of the un-germinated
barley. To overcome this problem, exogenous activity
can be obtained by adding enzymes during mashing.
With the correct enzyme mixture, beer can even be
made from 100 percent barley. It has been shown
that the product results in a good drinkable beer. The
question that remains is, ‘how does it affect the filterability of the beer?’

Since the introduction of Beer Membrane
Filtration (BMF) much information has
been gathered about the influence of the
malt quality on filterability. All the constituents in the beer that influence filterability, find their origins in the ingredients
used and the brewing process. Adding a
certain amount of barley to malt during
brewing or even using 100 percent barley
in combination with enzymes is gaining
more interest. Pentair X-Flow has recently investigated the effect on beer membrane filterability of these raw materials.
The older generation BMF systems required back flushing that was executed five to
10 times before a more extensive cleaning procedure. With the BMF-18, the back
flushing is a soak flush that reduces water consumption by 50 percent per flush while
achieving the same result.
Recent product enhancements have improved the ability to reuse chemicals in the
cleaning procedure, which reduces the chemical consumption by 30 percent. Both
cleaning improvements are part of any BMF-18 delivered today and are available as
retrofit packages for existing filter lines.
The third improvement of the BMF-18 is that it can be designed to run either in a batch
or in a continuous operation mode, depending on the brewery’s specific requirements. With continuous operation, two sets of membrane filter skids alternate; one
set is in filtration mode while the other one is in cleaning mode. Due to continuous
operation systems can be sized smaller which helps to reduce CAPEX.
These innovations make BMF-18 a more sophisticated product that offers a solution
for the ever-increasing demands in the brewing industry in terms of economy, quality and sustainability for breweries of all sizes.

ing the maximum allowed TMP increases significantly
at the variant using 100 percent barley. In figure 1, the
data of a blend of 50 percent malt and 50 percent
barley is given as well. Also here the filterability could
be im-proved compared to the 100 percent malt variant. Blending after fermentation is an option for the
brewer to tune the taste and body of a beer.
In Figure 2, all the data of the first comparison trials is
given. The first periods are normalized to the first
period of 100 percent malt. What can be clearly seen
is that the fouling rate reduces with higher barley
loading, resulting in an increased filterability.

Figure 2: Normalized filterability of the different
trials. In the case of 100 percent barley, the first
period is estimated to 32 hours.
The research clearly shows that substituting barley
for malt has a positive effect on the filterability of the
product. The enhanced filterability is most probably
due to the better conversion of the raw materials
during brewing. It also shows that the fouling rate
does not depend solely on the concentration of some
specific components, but much more on the nature
and specific interactions of the different components.

Pentair’s Everpure Claris
responds to market demands
for high volume water
treatment solutions
With 65 percent more capacity than the
original Claris™ system, the Claris XXL is
available for steam and combi ovens and
iced tea brewing.
Pentair’s Everpure® recently introduced an extension to
its line of popular Claris Water Technology systems, a
family of filtration and softening cartridges that provides both unpleasant taste and odor reduction for hot
beverages, and innovative scale control for foodservice
equipment. The new Claris XX-Large Filter Cartridge
(Claris XXL) extends customized scale prevention capabilities beyond standard coffee and espresso applications to include boiler and direct injection steam and
combi ovens, and iced tea brewing equipment.
A simple solution to a costly problem
Untreated hard water can be highly damaging to brewing and steam equipment by producing limescale which,
over time not only significantly increases the equipment’s energy consumption, but also can cause
increased service and life cycle costs. Some filter systems only control minerals by adding a scale-inhibiting
agent that keeps the minerals suspended in the water.
Claris selectively targets carbonate hardness using special ion exchange resin so that scale formation is almost
completely eliminated. This reduces the need for costly
delimings and service calls. In addition, the Claris blends
a small amount of filtered water with the softened
water, to create a “buffer” that keeps the water’s pH
level from becoming too acidic which can cause corrosion, and negatively effect the taste of coffee, tea and
other beverages. And because Claris is a quick change
system with a cartridge that is easily replaced when it
expires, there’s no need to add salt as with many softening systems, a task which is often neglected by
Smart chemistry and ingenious engineering
The new Everpure Claris XXL helps operators find the
right water quality balance to capture the specific taste
profile they desire. Specific features include:
A 5-stage filtration process:
• Prefiltration
• Carbonate hardness adjustment
• Fine filtration
• Highly efficient carbon block removes unwanted contaminant, unpleasant odors
and tastes
• Solid membrane filter removes particles down to 5 microns for a fine water polish
Consistency – DUOBLEND™ bypass valve
technology ensures a consistent and precise carbonate hardness level. Independent of the flow rate, the operator always gets the same water quality
Excellent contaminant reduction including scale-causing carbonate
Adds nothing to the water – Claris is unlike many scale-inhibiting systems that add
polyphosphate and ion exchange softeners that add salt to the beverages. Salt softening systems require salt replenishment and when a traditional softening system regenerates, salt gets washed into the ecosystem along with the wastewater. The Claris softens without salt thus adds nothing to the water and no salt or water is sent to drain.
A great alternative to reverse osmosis
The system also allows the operator to tailor the hardness to match the desired water recipe, a unique fea-
ture of the Claris design. This provides the benefits often
associated with reverse osmosis blending of filtered and
pure permeate water. The Claris blends filtered water
with water that has had the carbonate hardness
removed. Unlike reverse osmosis, there’s no need for
power or a drain, there’s no water waste and there’s no
need for a floor tank.
“The Claris XXL is an excellent option for operators who
want control of their water hardness, but don’t want
the expense, space requirements or additional maintenance associated with reverse osmosis,” said Tony
Fischer, product marketing manager of Pentair Everpure.
“The Claris provides consistent and precise adjustment
of the carbonate hardness, with the ease and simplicity
of quick change point-of-use filtration.”

Pentair Haffmans’ c-TPO
Optical oxygen measurement
at its best
written by peter houwen
Every brewer wants to ensure that customers enjoy the carefully brewed beer, bottle after bottle.
Contributing to an excellent beer is the fixed amount of carbon dioxide (CO2) and a minimized
oxygen (O2) content. Pentair Haffmans’ Inpack TPO/CO2 Meter, a state-of-the-art product solution
using optical O2 measurement technology, provides an advanced analysis of both Total Package
Oxygen (TPO) and CO2.
To ensure that bottled beer is of consistent high quality it is crucial to
pay extra attention to the product after the filling line. This is where
Pentair Haffmans’ Inpack TPO/CO2 Meter, type c-TPO, shows its
advanced innovation. Unlike conventional methods, the c-TPO measures both CO2 and O2 content as the bottle is filled with the beer
remaining in the package. The c-TPO pierces a hole in the bottle cap
and the sensor enters the package through this hole.
Established in Nantucket , Mass., USA, in
1997, Stirrings is an innovative provider of
premium cocktail mixers that is redefining
the way people enjoy cocktails. Believing
that better ingredients are the only way to
achieve a better tasting cocktail, Stirrings
uses the finest real fruit juice, triple purified
water and cane sugar to create a diverse
collection of super-premium Cocktail
Mixers, Rimmer® brand cocktail garnishes
and Classic Bar Ingredients. Its customers
are used to ordering premium Stirrings
mixers in cocktails such as Jose Cuervo
Especial® Gold Margaritas and Jeremiah
Weed® Sweet Tea Lemonade at their
favorite bar or restaurant but, thanks to
Stirrings’ recent partnership with Pentair
Foodservice, those drinks are now available
“on tap” like many beers and even some
wines are today.
knowhow 2011
Once Stirrings finalized its product specification, the
Pentair Foodservice team’s design ideation process
revealed that the majority of the key components
required to build the tap-based system already existed
within Pentair’s “tool kit”, among them:
SHURflo’s modular filtration system platform was modified to create a spirit well (each holds up to three liquor bottles in parallel).
SHURflo’s bag-in-box (BIB) rack holds the
BIB-style packaged cocktail mixes.
Two SHURflo BIB pumps and two Porous Media Air Vents form the fluid delivery system.
A shut-off mechanism was created by modify ing a Residential Flow Group strainer product.
One important fact that must be taken into consideration is that a
bottle is not filled with beer to the rim. The headspace between the
beer and cap is not filled with air, but with an inert gas, usually CO2,
which is present in the beer.
Pentair Haffmans’ c-TPO allows brewers to obtain a complete picture
of the filling process. In case of a deviation in the O2 level, fast and
effective intervention is possible, providing the highest process security for the filling process.
Pentair Foodservice has been a long-standing supplier
of SHURflo® pumps to Stirrings’ parent company,
Diageo® Europe, for wine delivery and other applications. Given Pentair Foodservice’s fluid solutions expertise, Stirrings approached them to help develop the new
“Cocktails on Tap” program. The goal being to design
and produce a cost-effective system that dispenses
a consistent, ratio-controlled spirit and cocktail mix
– finished drink – that is ultimately delivered via a
traditional beer-style tap.
Differentiated O2 measurement allows deeper insights
There are many opportunities after fermentation, during processing as
well as during bottling for O2 to enter the beer, which is why the
brewer encounters O2 in the bottle; in the beer and in the headspace.
Oxygen pick up into the beer itself can happen during filling and in the
headspace during bottle capping. Considering the fact that O2 in the
bottle causes severe damage to the beer, it is highly important to
know where the O2 originates from – the headspace or the liquid. Up
to now, it was impossible for the brewer to pinpoint the source of the
O2. Pentair Haffmans proven optical O2 measurement technology now
makes this possible. The c-TPO’s advanced sensor provides a differentiated measurement of headspace oxygen and the O2 content in the
liquid. This helps to identify the Total Package Oxygen (TPO) source.

Successful footprint reduction strategy
implemented with Pentair Südmo
Ganter Brewery’s new cold block on smallest possible area even more effective than before
Katharina Ganter Fraschetti
written by hans lange
The Ganter Brewery in Freiburg, Germany has implemented an efficient concept for a new cold block in cooperation with Pentair
Südmo that emphasises “quality not quantity”. This “size reduction
concept” cuts energy consumption and total operating costs allowing brewers to react to changing market requirements and run cost
effective production even at lower output levels.

At the Ganter Brewery, Pentair Südmo was responsible
for the entire concept, implementation and commissioning. The goal of the new plant design was to meet
the demand in terms of energy and cleaning agent consumption, while minimizing wastewater quantities in a
reduced footprint. In addition to saving energy and total
operating costs, production area was freed up for other
purposes. Construction of the plant took only six months
and after production started earlier this year positive
results were seen in just a few weeks.
combined in a minimum footprint, including yeast handling, connection of the tank farm for fermentation and
storage of unfiltered beer and after filtration connection
of the Bright Beer Tanks (BBT) with all secondary functions. The new keg system and tank unloading station
for the bottling facility are connected from here. In
addition to integrating and using existing parts of the
production plant, the advantage of Pentair Südmo’s
concept is the compact installation and the arrangement of the entire production line on the same level.
Entire production on one level
The brewery’s control concept is based on the “Proleit”
process control system that was programmed by
Pentair Südmo and is used by a growing number of
breweries. This user-friendly system allows the operator to easily adjust all parameters as each of the plant’s
components is clearly shown in a separate flow chart.
In a brewery the cold block is located downstream of
the brew house and includes all operations of the brewery from fermentation, maturation to filtration. At
Ganter the compact cold block is installed in a new

Pump supply for the Huascacocha water transfer project in Peru
Pentair Nijhuis’ first pump
order in South America
written by inge sluijter
Pentair Nijhuis’ pumps have been selected
as part of the water transfer system to feed
the Peruvian Huachipa drinking water
treatment plant benefitting 2.4 million
residents in Lima and neighboring Callao.
Pentair Nijhuis received an order from the
Brazilian construction firm Constructora
OAS Ltd. for the supply of four 855,000
gallons per hour (3,240 m3/h) capacity split
case pumps for this project.
The project includes building a 49 foot (15 m) dam wall
that will store almost 21 billion gallons (79
million m3) of water and building 14 miles (22.5 km) of
concrete channel, a 1.3 mile (2,1 km) tunnel and a 3.2
mile (5.1 km) long pipe line that is 4.9 feet (1500 mm)
in diameter. The water transfer system leads from the
Huascacocha Lake, via the Marca III system, to the
Rímac River in Lima, Peru. The end customer of this
project is Sedapal, Peru’s state-controlled water utility.
“From the Huascacocha facility the Pentair Nijhuis
pumps feed the Huachipa drinking water plant with a
capacity of up to 695 gallons per second (2.63 m3/s),”
said Damián Sciarra, Product Manager at Pentair’s
Argentina sales office. “OAS chose Pentair Nijhuis’
pumps, based on low energy consumption and low life
cycle costs for operation over a 25-year period.”
“The combined efforts of our partner Enerquímica in
Peru, colleagues in the Argentina sales office and
Pentair Nijhuis to penetrate the South American pump
market resulted in the first pump order in this continent,” concluded Frans Staring, Senior Area Sales
Manager, Pentair Nijhuis.
