The permeate produced in this phase has not yet reached its final quality. However, a part of it can be used to thin the
antiscalant in the canister.

Let the unit run for 10 minutes in this mode and continue with the adjust- ment of the recovery rate.

The system starts the permeate production.
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).
Using the example of 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 (%) = permeate*
x 100
permeate* + concentrate*
* quantity
Notice:
• When using an upstream softening system you can reduce the amount of concentrate (lower water consumption) until a
recovery value of 75% is achieved.
• Please also note the information on the correction value (chapter 4.2).
• Use the red markings to document the required flow rates
Notice:
If the permeate quantity (Fl01) is within the specified range (see technical data), continue with chapter 8.3
