If the day interval since
the last permeate output
has been reached at the
programmed time, forced
operation or forced
withdrawal takes place –
depending on what is
activated.
For AVRO 125 TS, only
forced withdrawal
is permitted in
conjunction with the
solenoid valve forced
withdrawal option!

4.1 How to set the system recovery
A certain part of the feed water must be rejected in order to prevent
the membrane from clogging due to scaling. The ratio of the produced
permeate volume to the feed water volume is called recovery.
4.1.1 How to set the permeate volume
Switch on the system at the control unit by pressing the "ON" button.
Use the adjustment valve operating pressure (refer to fig. F-3,
no. 1) to throttle the pump in such a way that the specific permeate
flow rate 125 l/h is achieved.
Note
: The current permeate flow can be displayed via
the control unit (refer to chapter F, point 2.1 Reading the
operating status.
