VIVENDI WATER STI
Description
INTRODUCTION
The Eclipse Two Stage Automatic Deioniser is designed to produce high quality deionised
water, and comprises two glass fibre ion exchange pressure vessels connected in series. The
first vessel (on the left hand side when viewed from the front) contains a cation ion-exchange
resin. The second, right hand vessel contains Anion ion-exchange resin. A control panel fitted
at the top of the vessels houses an electronic controller that controls the Deioniser during
service and resin regeneration, and provides interlock control functions with other plant.
The water quality is monitored by a conductivity meter that is factory set to 30
microsiemens/cm. When the conductivity of the treated water rises to this level, the Deioniser
outlet valve automatically closes, and the Deioniser commences a rinse to drain. If the
conductivity at the end of the rinse period has returned to normal, the deioniser will return to
service. If however, the conductivity remains above the set point, the control automatically
commences the regeneration procedure. This pre-regeneration rinse prevents unnecessary
regenerations should there be a temporary drop in water quality for some reason, and at the
same time, ensures that only good quality water is passed to service, it is normally set to 8
minutes. However if the deioniser service automatically recycles to the break tank at times of
low demand this rinse time is set to minimum.
REGENERATION
Regeneration consists of injecting dilute hydrochloric acid through the cation ion-exchange
resin, and dilute caustic soda through the anion resin. In both cases, this is preceded by
backwashing to remove any resin ‘fines’ that may have collected on top of the resin, and to
loosen the resin bed prior to chemical injection, and is followed by a rinse to drain to remove
residual chemical and regeneration product.
The regeneration procedure is carried out automatically, and is initiated either by the
conductivity meter as stated above, or manually by a push button located on the Control Panel.
When both vessels have completed regeneration, (cation first, followed by the anion vessel) the
Deioniser is rinsed to drain or recycled to the break pressure tank and the conductivity of the
treated water monitored. When the conductivity drops below the set point i.e. when all the
residual chemicals have been flushed from the vessels and pipework, the Deioniser
automatically returns to service.
CHEMICALS
The required strength of the hydrochloric acid and caustic soda is given in the Technical Data,
and the arrangements must be made to obtain regular supplies. The acid and caustic soda is
drawn from carboys or regeneration tanks (optional) by the acid and caustic injectors which
form an integral part of the vessel valve head assembly.

Installation
INTRODUCTION
The work detailed below must be carried out by a competent plumber and electrician.
When the installation work has been completed, the Deioniser can be commissioned (set to
work). If the customer’s order includes for the services of a company engineer to commission
the plant, he should contact the Service Office as listed in AFTER SALES SERVICE, and
arrange for a regional engineer to call.
The work necessary to commission the Deioniser is detailed under COMMISSIONING.
INITIAL PREPARATION
Because deionised water can be contaminated easily, it is advisable to have the plant located
as close as possible to the point of use of the treated water.
Hydrochloric acid and Sodium Hydroxide (caustic soda) used to regenerate the resins are very
corrosive chemicals, and consequently must be kept out of the way of the public and
uninformed staff.
FOUNDATIONS AND DRAIN
No special foundations are required, providing a firm and level surface capable of supporting
the working weight of the Deioniser (see Technical Data) is available.
An open gully capable of handling the 15% acidic and alkaline solutions and the maximum
drain flow shown in the Technical Data must be available or constructed within 3 metres of the
installation.
Because of the corrosive nature of the waste effluent flowing to drain during the regeneration
procedure, the local water authorities must be consulted before disposal into local river streams
and municipal sewers.
HEAD ROOM AND OPERATING SPACE
When installing the Deioniser it is important to ensure there is: Access to the front of the Deioniser for controls operation.
 Adequate space to change and manoeuvre the acid and caustic soda carboys
(or refill optional regenerant tanks).
 Access to the rear of the installation is available for maintenance work 300mm minimum.
 A height of 400mm above the unit.
The overall dimensions of the plant are given in the Technical Data.
WATER PRESSURE
Minimum:
Maximum:
3.5 bar
7.0 bar
NOTE: The water to the Deioniser must be clean and free from suspended solids and organic
matter.

WATER TEMPERATURE
Maximum
Minimum
Minimum
40°C (at maximum pressure)
The Deioniser and drain pipework must not be subjected to freezing conditions.
Ambient 15°C
Note: The minimum ambient temperature is specified because below 15°C caustic soda
becomes very viscous and starts to freeze, making chemical injection into the unit extremely
difficult.
PIPEWORK CONNECTIONS (TO BE PROVIDED BY CUSTOMER)
 Fit the inlet isolating, check and anti-vacuum valves or alternatively break pressure tank and
booster pump and inlet isolating valve to the raw water supply pipework as shown
diagrammatically on the schematic pipe connection diagram. Flush out all swarf and debris
from newly made connections and pipework.
Note: A break pressure tank is required to confirm to Local Water Authority regulations in the
U.K. and may also be required to increase the raw water supply pressure. Information on
suitable break pressure tanks is available on request from VIVENDI WATER STI.
 Fit the outlet isolating valve to the treated water pipework. All treated water pipework and
fittings must be made in uPVC, PVC (Polyvinyl Chloride), ABS (Acrylonitrile Butadiene
Styrene) Polypropylene, Stainless Steel or suitable lined piping - standard plumbing fittings
such as copper or galvanised piping must not be used.
 Place the deioniser into position. The front face of the control panel must be accessible and
easily observable.
 Make final connections between the inlet and outlet isolating valves and inlet and outlet
connections. Direct the individual valve drains to a suitable drain or gully. The Final rinse
drain should also be directed to the drain or gully unless final rinse recycle has been
specified when it should be directed to the break pressure tank (see TECHNICAL DATA for
connection details).
ELECTRICAL SUPPLY AND TERMINAL CONNECTIONS
The mains electrical supply is to be connected to the Deioniser control box terminals via a fused
and earth connected switch. The 220/240V supply to the control box should be fused 1 amp or
3 amp for 110v/120v supply.
Note: If unit has been supplied for 115v supply voltage, check links are correctly positioned as
shown in terminal connection diagram.
All wiring and electrical installation must comply with the B.I.E.E. Regulations 16th Edition or
local rules.

Commissioning
INTRODUCTION
Before the Deioniser can produce treated water, the following Commissioning procedure must
be carried out.
If the services of a Commissioning Engineer are required, contact the Service Office as listed
under After Sales Service, or the local agent to arrange for an engineer to call.
PRE-SERVICE BACKWASH
Check that the power supply is switched off and that the inlet and outlet isolating valves are
closed.
Remove the cover from the cation and anion control valve assemblies.
Push the red knob in on the end of the cation control valve camshaft and rotate and camshaft
anticlockwise until the arrow on the knob points to the annular segment of the
backwash stage indicator diagram, then release the knob.
Crack open the manual inlet isolating valve (do not open fully at this stage as opening the valve
fully with air trapped in the vessel may bring resin over into the drain.) until water, free of air,
flows from the cation regeneration drain and the rinse drain. This could take up to 10 minutes.
When water free of air is flowing, push the red button in again and rotate the camshaft
anticlockwise until the arrow is near the end of the annular segment of the final rinse stage
diagram. Release the knob.
 Select Auto/Manual Switch to Manual.
 Turn on the electrical supply, the regen lamp will flash.
 Push the ‘Reset’ button.


 The valves will now rotate to the Service position.
 The regen lamp will start to flash again after a short time.
 Switch off the electrical supply.
ATTACHMENT OF CARBOYS (OR OPTIONAL MEASURING TANKS)
The required strength of hydrochloric acid and caustic soda is given in the TECHNICAL DATA.
The acid and caustic soda is drawn by injectors which form an integral part of Deioniser valve
assembly.
WARNING: BOTH OF THESE CHEMICALS ARE CORROSIVE AND THEREFORE,
CHEMICAL GOGGLES, RUBBER GLOVES, BOOTS AND PROTECTIVE CLOTHING MUST
BE WORN WHEN HANDLING AND CHANGING THE CARBOYS. THE OPERATING STAFF
MUST BE PROPERLY TRAINED AND INSTRUCTIONS FOR FIRST AID AND THE
HANDLING OF SPILT CHEMICALS DISPLAYED IN THE AREA.
 Place the acid carboy on the left of the deioniser (when viewed from the front) and the
caustic soda carboy on the right.
 Fill the carboys with chemicals as stated under acid and caustic carboy filling in the
Operations Section.
 Remove the caps from the top of the carboys, and replace with the draw tube assemblies
provided (see NOTE below). Leave about 25mm between the bottom of the stand pipe and
the carboy as shown.
NOTE: Ensure that the correct draw tube assembly is attached to the correct carboy. The
connection from the Anion valve marked NaOH must be connected to the caustic soda carboy,
and the connection from the Cation valve marked HCl to the Hydrochloric Acid carboy.
CONNECTING TO OPTIONAL REGENERANT TANKS
 If optional regeneration tanks are to be fitted the drawtubes are simply connected to the
compression fittings at the rear of the regeneration valves. Ensure that the tank marked
Acid/HCI is connected to the Left Hand Valve (Cation) and the tank marked Caustic/NaOH is
connected to the Right Hand Valve (Anion). If level switches have been supplied ensure that
these are wired as shown in the wiring diagram, these tanks are normally to be filled using a
Chemical transfer Pump (not supplied) care being taken to use the operating instructions
supplied with any such pump and the safety instructions supplied by your chemical
regenerant supplier.
 If the installation area is poorly ventilated, connect a tube between the carboy bung or tank
breather and the outside to prevent the possibility of corrosive fumes building up. Note that
this line must be free of kinks otherwise the plant will fail to regenerate. Alternatively a fume
scrubber can be fitted to the carboy or regenerant tank. Contact the service office as listed
under After Sales Service or your Local agent.


 Caustic soda starts to come out of solution at +15°C. Starts to freeze at +8°C and is
completely solid at +5°C. The ambient temperature must be above 15°C.
NOTE: ONLY LIQUID CAUSTIC IS TO BE USED 30% W/W PREFERRED, OR 46% W/W.
PUTTING INTO SERVICE
 Ensure the Manual/Auto switch is set to Manual.
 Ensure the Inlet and Outlet Isolating valves are closed.
 SWITCH ON electrical supply.
 Slowly open the Inlet Isolating valve fully.
 Press the regeneration initiation push button until the regeneration lamp comes on (around
10 seconds) and allow the unit to regenerate. (Ensure chemical carboy or tank has been
installed).
 At the end of approximately 2.5 hours, the unit will have finished regeneration. If the water
quality is below the conductivity set point, the plant will be ready for service. If the water
quality is above the conductivity set point, manually rinse the plant by operating the reset
push button until good quality water is achieved.
 Set the Deioniser into Manual or Automatic mode as required.
 Slowly open the outlet isolating valve to allow treated water to service.
 The Deioniser is now in normal service.

VIVENDI WATER STI
Operation
INTRODUCTION
Once the Deioniser has been properly installed and set to work, the only regular attention will
be to change the acid and caustic soda carboys, or refill the optional regenerant tanks.
Ensure that the safety precautions outlined at the beginning of this manual are followed whilst
carrying out the following procedures.
CHANGING ACID AND CAUSTIC SODA CARBOYS
When the level of chemical in the carboy approaches the bottom of the draw off stand pipe, the
carboy must be changed. The quantity of chemical required for one complete regeneration is
given under the Technical Data. If there is less than the required amount left above the stand
pipe, the carboy must be changed.
To change the carboy, remove the bung and stand pipe from the carboy and replace in a full
carboy containing the same chemical. Confirm that breather tube is clear and unobstructed.
REFILLING OPTIONAL REGENERANT TANKS
When refilling optional regeneration tanks a proper acid/caustic transfer pump should be used
in accordance with manufacturers safety and operating instructions. DO NOT OVERFILL.
CAUSTIC LIQUOR FROM PEARL OR FLAKE
The amount of 100% w/w caustic pearl/flake required per litre of deionised water is shown
under technical data.
Before mixing, read WARNINGS at front of manual.
 DO NOT mix in the caustic soda carboy or tank.
 The mixing must be done in a well ventilated and safe area.
 Add the caustic pearl/flake in 50 to 100 gram doses to the deionised water and thoroughly
mix. Allow to cool between doses, see note below.
Note: This mixing causes a reaction resulting in the solution becoming very hot (and can boil if
added too quickly) therefore, use a mild steel or enamelled steel mixing container and
implement.
CHECK LIST IN CASE OF DIFFICULTIES
If the Deioniser fails to deliver deionised water during the service run, or the service run is of
short duration, carry out the following checks before requesting a visit by a service engineer.
BYPASS VALVE
Check that the manually operated bypass isolating valve is closed. If the valve was open,
106755469
Fisher Bioblock Scientific
page 19
VIVENDI WATER STI
Operation
close it. Deionised water will then be available to service again, although it may take a little
time for the treated water to displace all of the untreated water admitted via the bypass to the
service line.
INLET AND OUTLET ISOLATING VALVE
Check that the Deioniser inlet and outlet isolating valves are open. If either of the valves is
shut, open the valve.
POWER FAILURE
If the electrical supply has failed or has been inadvertently switched off during regeneration, the
sequence controller will automatically hold in the part of the sequence where it stopped and the
pump will stop. On resumption of power the regeneration lamp will flash. Pushing the ‘reset’
button will allow the unit to continue its regeneration, with the regeneration lamp on
continuously until the regeneration is complete.
If power fails during service, on resumption of power the ‘reset’ button should be pushed
momentarily, the unit will then rinse to quality and return to service automatically if quality is
good.
FINAL RINSE FAILURE
If the Deioniser fails to rinse down to good quality at the end of regeneration, the alarm lamp will
flash, and the Deioniser will not return to service. The plant operator must then investigate the
cause of the failure as shown on the Control Logic Diagram. When the cause has been
rectified the Deioniser must be restarted as follows.
MANUAL REGENERATION
Select the Auto/Manual switch to Manual, press the Reset button and hold for 10 seconds. The
regen lamp will light and regeneration has been initiated
Select Auto/Manual switch to normal operating mode, unit will continue in normal service at the
end of the regeneration assuming the regeneration has been successful.
ACID AND CAUSTIC SODA CARBOYS OR OPTIONAL TANKS
Check that the carboys/tanks contain chemical and that any sludge in the bottom of the
carboy/tank is not obstructing the draw off stand pipe. Check that the vent in the stand pipe
bung or tank top is not obstructed.
If the above check fails to highlight the trouble, contact the Service Office as stated in After
Sales Service, or your local agent.
ADJUSTMENTS
The conductivity set point, scale range, Rinse Check and Final Rinse times, and the chemical
injection cams are preset at the factory, but can be readjusted as follows if necessary.
However, these adjustments should normally be left alone and only altered on the advice of
VIVENDI WATER STI.
106755469
Fisher Bioblock Scientific
page 20
VIVENDI WATER STI
Operation
CONDUCTIVITY METER SET POINT
This factory set to 30 microsiemens/cm and can be checked by pushing the ‘set level’ button
fitted to the left and below the conductivity meter.
ADJUSTING THE CONDUCTIVITY SET POINT
This is set by pushing the ‘set level’ button in and adjusting the ‘set level’ potentiometer (fitted
next to the button) clockwise for higher setting or anticlockwise for lower setting.
TIMER ADJUSTMENTS
Normally no adjustment is required, pre-regeneration rinse is set to minimum for units that are
to continuously recycle treated water to the break pressure tank with conductivity override
where a pre-regeneration quality rinse is required. This is adjustable from 2 to 15 minutes.
Post regeneration quality rinse is factory set to a maximum of 40 minutes as this is overridden
by good conductivity when this occurs.
Acid and caustic times are adjusted by changing the draw cam. The cam fitted as standard will
give correct draw times when the plant is operated between 4 and 4.5 bar. Where higher or
lower pressure than this is present, a set of cams is available to replace the draw cams fitted at
the factory. The higher the available pressure, the smaller the cam segment that should be
used. Fine adjustment of Acid or Caustic Draws can be made using the draw line ball valves.

VIVENDI WATER STI PERMUTIT PLANNED MAINTENANCE
VIVENDI WATER STI Permutit Planned Maintenance, PPM, offers regular servicing at predefined intervals and includes regular replacement of identified service components.
PPM is a preventative maintenance programme designed to minimise the amount of plant down
time. Plant which is operated with inadequate service levels is liable to more frequent
breakdowns. These are not only inconvenient, but can cause lost production and expensive
down time.
PPM enables you to operate the plant at peak efficiency, can eliminate excessive use of
regenerants, and prevent damage to plant and production facilities which use the treated water.
Our Engineers carry out a comprehensive series of designated checks and tests, as well as a
detailed general inspection of the plant. Key working components are dismantled, cleaned and
reassembled using new parts. Necessary adjustments are made to leave your plant working
correctly and efficiently.
PPM is a flexible service; the number and timing of visits can be adjusted to suit your particular
site conditions and operating requirements. PPM provides a complete maintenance programme
tailored to meet your needs:

 Regular planned visits by qualified VIVENDI WATER STI Engineers to carry out an identified
service
schedule.
 Detailed Engineer's report provided prior to leaving site advising work completed and
recommending any future actions in order to enhance the operation of your plant.
 Service Spares Pack provided as part of the maintenance service.
 Strategic Spares recommended and provided at a preferential price to PPM customers.
 24 or 48 Hour Guaranteed Fast Response (GFR) available.
 Breakdown site time inclusive (BSI) option available.
 Discount on replacement plant purchase.

ANALYTICAL SERVICES
VIVENDI WATER STI offers a complete range of Analytical Services to test and examine
samples of media, raw and treated water, to assist with the identification and resolution of
chemical and operational problems.
We provide a full technical report of the sample analysed and give detailed recommendations.
Once problems are correctly identified, we advise the correct action to resolve or prevent future
occurrences.
WATER ANALYSIS
Regular analysis of inlet feed water supplies provides information regarding the level of solids
being presented to the unit; this information will help you to operate your Water Treatment Plant
efficiently. Analysis of the feed supply will also indicate whether contaminants are present and
our report will advise you what actions should be taken to minimise or prevent future problems.
Treated water samples are frequently analysed as part of our trouble shooting activities in order
to determine how the media is performing and to indicate where problems are originating.
MEDIA ANALYSIS
Analysis of media samples, ion exchange resin and filter medias, provides information as to
whether contaminants are accumulating within the media bed which may affect the quality and
volume of water produced by your units. The results also provide information about the
expected life of the media which can be related to your feed water quality and method of
operation.
If there is a problem, it is important to be able to diagnose it quickly and take appropriate action
to rectify. A correct and early diagnosis can prevent unscheduled down time. The performance
of the media can be monitored over time and replacement arranged to suit you. As the media
ages, additional amounts of regenerant are required to produce the same volume and quality of
treated water. Chemical regenerant costs can be saved by replacing the media at the optimum
time.
Please contact the VIVENDI WATER STI Service Office or your local VIVENDI WATER STI
Agent should you require any analyses.
