2. Applications
2.1 Water treatment
BME and BMET booster systems are ideally suited for water treatment systems.
Typical applications are desalination systems, irrigation systems and process water purification systems:
Desalination
systems
Desalination systems are grouped according the chloride content of the raw water:
1. Brackish water: 501 to 10000 ppm Cl- and a pH value of 4 to 9.
2. Sea water: 10001 to 50000 ppm Cl- and a pH value of 4 to 9.
Desalination systems are used for the production of:
Irrigation
systems
Industrial
process water
•
potable water
•
industrial process water
•
purified water for food production
•
purified water for pharmaceutical appliacations in the medicinal industry
•
water for irrigation of cultivated land.
Irrigation systems have many fields of application, the most important being:
•
horticulture
•
sports centres, e.g. stadiums, golf courses and
•
recreational areas, such as parks.
Process water (water used for nonpotable industrial usage) is used in manufacturing
processes or generated during manufacture or production processes. Water is often specifically treated to obtain the quality required for a process.
Process water occurs in connection with:
•
boiler feed water
•
wash systems for cars, trains, planes etc.
•
chip production.
2.2 Pumped liquids
The booster modules are suitable for the pumping of thin, non-explosive liquids not containing solid particles or fibres. The liquid must not attack the booster module materials
chemically. If in doubt, contact Grundfos Management A/S, Denmark.
Note: The booster modules must not be used for the pumping of flammable liquids such
as diesel oil, petrol and similar liquids.
It is advisable to filter raw water to maximum 10 microns (PLG).
The booster modules must never run with water/a liquid containing substances that will
remove the surface tension, e.g. soap. If the water/liquid contains this type of detergent,
the modules must be bypassed.
Note: During transport and storage booster modules must never be preserved with glycerine or other substances which are aggressive to the booster module materials.
See the Pumped Liquid Guide (PLG) for further information on permissible pumped liquids.

Function
BME, BMET
6. Function
BME and BMET booster modules are primarily designed for desalination systems using
reverse osmosis (R.O. systems). The following sections explain the function of BME and
booster modules used for desalination by means of reverse osmosis.
Reverse osmosis
Reverse osmosis systems are an environmentally acceptable method for desalination of
water – without addition of chemicals. A high-pressure pump presses raw water into a
membrane system which only allows desalinated water to pass through.
The salts retained are discharged as concentrate (brine) or utilized as energy to drive the
BMT pump or an energy-recovery system.
6.1 BME in reverse osmosis systems
The feed pump must deliver the required flow and inlet pressure to the BME module.
Start-up
When the system has been vented, the BME module builds up the membrane pressure.
When the pressure exceeds the osmotic pressure, the permeate production begins.
During operation
The BME module delivers the pressure against the semi-permeable membrane. As long
as the pressure exceeds the osmotic pressure, water molecules pass through the membrane, resulting in permeate or desalinated water. Salt molecules are retained by the
membrane and led back to the raw-water source as concentrate.
Result
30 to 40% of the raw water becomes permeate, and the other 60 to 70% are discharged
as waste.

Function
6.2 BMET in reverse osmosis systems
The feed pump must deliver the required flow and inlet pressure to the BME and BMT
modules.
Start-up
When the system has been vented, the BME module can build up pressure against the
semi-permeable membrane. No permeate will produced until the BMT module is operating, as the BME module cannot deliver the required pressure itself.
During operation
When the BMT module is operating, the BME and BMT modules are connected in series
and will deliver sufficient pressure to start the reverse osmosis through the semi-permeable membrane, and the production of permeate begins.
When the pressure against the semi-permeable membrane exceeds the osmotic pressure, water molecules pass through the membrane, resulting in permeate or desalinated
water. Salt molecules are retained by the membrane and led back to the raw-water
source as concentrate.
Energy recovery
The high pressure (energy) on the inlet side of the membrane is utilized by leading the
concentrate to the turbine wheel of the BMT module.
Result
30 to 40% of the raw water becomes permeate, and the other 60 to 70% are discharged
as waste.

8. Installation
GRUNDFOS BME and BMET booster modules are delivered from factory in crates, ready
for installation. The booster module should remain in the packing until it is to be
installed.
Note: During transportation and storage, the booster modules must never be preserved
with glycerine or similar liquids which are aggressive to the booster module materials.
8.1 Installation
The booster modules can be mounted directly on the floor. The modules are adjusted by
means of four adjustable feet.
8.2 Pipe connection
Pipes are connected to the booster modules by means of Victaulic/PJE clamp couplings.

Installation
The BMET booster module also has a PJE clamp on the turbine inlet and a connection
(ø300) for a flexible hose for concentrate outlet.
On BMET systems, the hose (ø300) is fastened to the outlet of the turbine housing with
a strap. The hose is led to a drain tank, drain channel or similar drain.
Note: The concentrate outlet must be kept free under all operating conditions.
The end of the hose should always be mounted above the highest possible water level in
the drain. The hose should be supported.
Note: If a discharge pipe is connected to the concentrate outlet, this pipe must have an
air inlet.

Fig. 17 Wiring diagram
The required voltage quality measured at the motor terminals is –5%/+5% of the rated
voltage during continuous operation.
There must be voltage symmetry, i.e. approximately same difference of voltage between
the individual phases.
The motor is wound for star-delta starting.
The following starting methods can be used:
•
star-delta starting,
•
soft starter or
•
frequency converter.
The longest permissible run-up time for star-delta starting is 2 seconds. When starting
up via soft starter or frequency converter, the run-up time up to 50% of rated frequency
should not exceed 2 to 3 seconds. The run-out time from 50% of rated frequency to 0
should not exceed 2 to 3 seconds.
During frequency converter operation, it is not advisable to run the motor at a frequency
higher than the rated frequency (50 or 60 Hz), see motor nameplate.
16.02.04/PI-051

BME, BMET
Installation
8.3.1 Motor protection
The motor must be connected to an effective motor starter (MV) and an external amplifier relay (FR), see fig. 17. This protects the motor against damage from voltage drop,
phase failure, quick and slow overloading and a locked rotor.
In electricity supply systems where undervoltage and variations in phase symmetry may
occur, a phase failure relay should be connected.
8.4 Periods of inactivity
In the case of periods of inactivity exceeding 30 minutes, it is important to:
•
flush the system through with clean fresh water and
•
disconnect the automatic greasing system by turning the switches to position OFF.
If the system is taken out of operation for a period, it is also important to
•
slacken the V-belt and
•
rotate the motor and pump shafts regularly.
8.4.1 Flushing of the modules
The booster pumps must be stopped while the system is flushed.
BME:
The booster modules can be flushed through in or against the flow direction, see fig. 18.
BMET:
The booster modules must be flushed through against the flow direction, see fig. 18.
Note: The distributing pipe for nozzles must also be flushed through.
Flushing can for instance be effected through small quick-couplings or gate valves (not
supplied with the booster module) fitted either side of the high-pressure pump.
Flush the system through for approx. 10 minutes until it is completely filled with clean
fresh water.
Note: If the flushing takes more than 10 minutes, the flow must be reduced to maximum
10% of the rated flow.
The modules must be filled with clean fresh water during periods of inactivity.

8.5 Oil change
The hydraulic oil should be changed every 2,000 operating hours or every 6 months.
Total quantity of oil: Approx. 1.5 litres.
During operation, the oil must be changed as follows:
1. Switch off the level switch in the oil container or establish a time delay of approx. 10 minutes.
2. Open the drain valve, see fig. 19. Oil will now run out of the oil drain pipe.
3. Close the drain valve when the oil container is almost empty.
4. Fill in new oil up to the maximum level mark on the oil container.
5. Open the drain valve.
6. Close the drain valve when the oil container is almost empty.
7. Fill in oil up to the maximum level mark on the oil container.
8. Open the drain valve.
9. Close the drain valve when the oil container is almost empty.
10. Fill in oil up to the maximum level mark on the oil container.
Approx. 1.5 litres of hydraulic oil has now been filled into the container.
11. Check the oil level after 1 to 2 hours of operation and refill, if required.
The oil has now been changed.
If the oil lubrication system has been dismantled during repair, the system must be filled
as follows:
1. Check that the drain valve is closed, see fig. 19.
2. Fill new oil into the oil container, approx. 0.5 litres, and wait approx. 10 minutes
until the oil level has fallen.
3. Fill in oil up to the maximum level mark on the oil container.
4. Start up the booster module.
The oil level in the oil container will now fall.
5. During operation, fill in oil up to the maximum level mark on the oil container.
6. Check the oil level after 1 to 2 hours of operation and refill, if required.
During operation, the oil level in the container must lie between the minimum
and maximum marks.
During inactivity, the oil level in the container may fall below the minimum
mark.
The oil lubrication system is now filled with oil
