8.2 Adjustment of the permeate
quality
Adjust the circulation volume (BV02) and the
concentrate volume (BV03) to achieve the
optimum recovery and permeate value (see
technical data). The flow rates can be read off
the flow measuring sensors FI01 (permeate) /
FI02 (circulation) and FI03 (concentrate).
Fl01 permeat flow meter
Fl02 recirculation flow meter
Fl03 drain flow meter
BV02 manual recirculation control valve
BV03 manual drain control valve
BV04 manual flushing control valve
SV02 flushing solenoid valve
D permeat conductivity probe
E attachment for sampling permeat
Using the example of WL-ROL-1000:
Circulating flow rate: 450 l/h
Concentrate flow rate: 470 l/h
This results in a recovery value of 68 percent.
In general, this is calculated as follows:
RECOVER (%) = permeat* x 100
* quantity
• When using an upstream softening
system you can reduce the amount of
concentrate (lower water consumption)
until a recovery value of 75% is achie-
ved.
• Please also note the information on the
correction value (chapter 4.2).
• Use the red markings to document the
required flow rates
If the permeat quantity (Fl01) is within the
specified range (see technical data), continue
with chapter 8.3.
