5.1.2 How to set the concentrate volume
Set the concentrate flow at the concentrate needle valve (refer to fig.
F-4, item 1).
To safeguard against the valve changing its position, it features a
safety screw which is centrally located at the green cap.
The concentrate flow in a standard system has to be set in a way, that
a recovery of 50 % is attained (400 l/h of permeate flow, 400 l/h of
concentrate flow).
Note:
The current concentrate flow and the recovery can be dis-
played via the controller (refer to Chapter F, paragraph 2.1 “Reading
the operating status”).
Attention!
If the set recovery is not met, scaling (precipitation of dis-
solved salts) occurs on the reverse osmosis membrane.
