4.1.2 How to set the concentrate volume
Set the concentrate flow at the concentrate needle valve (refer to
fig. F-4, no. 1)
The concentrate flow in a standard system has to be set in a way,
that a recovery of 75 % is attained (125 l/h of permeate flow, 42 l/h
of concentrate flow)
Note:
The current concentrate flow and the recovery can be
displayed via the control unit (refer to chapter F, point 2.1 Reading the
operating status).
Caution!
If the set recovery is not met, scaling (precipitation of
dissolved salts) occurs on the reverse osmosis system.
Measure water values of feed water, permeate, concentrate after
10 minutes and enter them in the operating log.
Switch off the system ▼ (refer to chapter F-2).
