8.2.1  Increase of the working pres- sure before the membranes

If the maximum permeate quantity (Fl01*) is not reached although the recovery value cor- responds to the 

specifications in the technical data, you can increase the permeate quantity by increasing the pressure before the mem- 

branes.

 Notice:

Do not exceed the permitted pump pressure!

This can lead to pump damage.

Select a low working pressure!

Although the diaphragms can be operated at a pressure of 5 to 12 bar, we recommend the lowest possible working 

pressure (5 to 6 bar), both during commissioning and during nor- mal system operation. This allows for a lon- ger service 

life of the diaphragm(s).

To increase the pump pressure, proceed as follows:

Rotary vane pump (in models from 100 l/h to 320 l/h):

» 

Open or close the by-pass valve (bypass) with a slotted screwdriver

* see figure previous page

Fig. 8.a

Multi-step pump (in the models from 460 l/h to 1.000 l/h):

» 

Adjust the ball valve downstream of the pump manually

Fig. 8.b

» 

Watch the pressure change on the manometer downstream of the pump and the flow rate change on the 

 

pure water flow meter.

» 

Adjust until the desired flow rate is reached.

» 

Let the system run for 30 minutes.

» 

During this time, periodically check that the rated parameters (flow rates, pressures and conductivity) stabilise 

 

within the limit values.

» 

Take a permeate sample (at the extraction point (E*)) and, if neces- sary, carry out a chemical-physical and 

 

possibly bacteriological analysis to check the suitability of the water for the intended purpose.
