4. INSTALLATION
41. PREPARATION
The hull fitting and the hull valve (V0) are supplied and installed by the work site.
The sea water feeding hull fitting (EdM) should be placed as low as possible below the water line, in an area always immersed whatever the
boat's navigation rate may be.
The hull valve (V0) should be placed on the sea water feeding pipes, as close as possible to the hull fitting.
The reject hull fitting (R) should be placed above the water line.
42. PLACING THE UNIT (see on board installation layout p22)
- Place the low-pressure (LP) and high-pressure (HP) pump on the boats motor so that it is rigidly
- Choose the speed ratio enabling the desalination unit to function with the high-pressure pump at 1500 rpm, corresponding to an 800l/hour
volume of seawater. This volume is shown by the seawater
- The filters must be installed vertically on a wall using the support with which they are equipped. If necessary, it is possible, however, to incline
it slightly from the vertical.
- Connect the seawater inlet (EDM) to the strainer (1). Be careful of the position of the 3-way valve (2) (attached to the strainer).
- Connect the strainer to the booster pump inlet (or low-pressure pump) (3) using the pipe
- Connect the booster pump outlet to the pre-filtration inlet with the pipe (C), paying attention to the direction of the flow in the pre-filtration unit.
- Connect the pre-filtration unit to the seawater flowmeter using the pipe (D). This flowmeter will help you to regulate the pump speed by fixing
it at 800 litres/hour.
- Connect the flowmeter to the high-pressure pump inlet with the pipe (F).
- Connect using the high-pressure flexible hose, from the discharge to the membranes module inlet. These connections are mounted stainless
on stainless, without gasket, without paste and without Teflon.
- Coming out of the module under the control unit, connect with the pipe (L) towards the T-Junction of the permeate waste discharge (P) and
the seawater waste discharge (O).
- Connecting the production of permeate /soft water in the middle of the membranes towards the production flowmeter (14) and the probe
support (15) by pipe 08/10 (l).
- Flowmeter outlet towards the 3- way valve (16) of the waste by (J).
- Discharge of the water production if the salinity level is too high, by (P) towards the waste T-Junction mentioned above.
- Outlet of the conforming water production to your storage tank by (K).
43. ASSEMBLING OF FITTINGS AND PIPES
Assembling of fittings.
When installing the unit it may be necessary to dismantle and assemble the fittings with which it has been
equipped.
WARNING : The fittings must be absolutely clean. Clean the fitting and its housing beforehand by
removing any remaining scraps of Teflon.
Wind Teflon round the fitting thread, by turning clockwise (Fig.1). Place the fitting in its housing, and tighten by
hand. Insure tightening with a slight turn of a spanner.
Assembling of pipes.
The necessary pipes are supplied in rolls, to be cut to the right length depending on needs. The cut, using a
cutter; should be clean, without blunders, and perpendicular to the axis of the pipe.
WARNING : The pipes must remain completely clean Check, when installing, that no impurities have
been introduced, notably during cutting : sand, plastic chipping...
The pipes are connected as indicated in "onboard installation". The produced water pipe (K) is connected to the
upper part of the tank.
WARNING : Do not immerse the piping in the tank.
The rinsing (E) and cleaning (N) pipes are long enough to be immersed simultaneously in an auxiliary bucket
placed on the ground, during membranes rinsing and cleaning operations (Chap. 7).
To assemble a pipe on its fitting, proceed as shown on Fig. 2 :
1- Place the hose clamp, without tightening, then place the pipe on the fitting,
2- Slide the hose clamp to the fitting level and tighten it with tongs,
3- To dismantle the pipe, slide the clamp with the help of a screwdriver, then free the fitting tube
flowmeter.
