Parameter setting
The parameters are adjusted to the specific tasks
(s. section 6.3).
Start-up process:
The membrane station should be set in water up to the mid line of the back flushing tank for start-up. It
may take up to 30 minutes for the water to be pressurized in the suction chamber of the pump. Initially,
Only now the test mode of the suction pump can be started as the pumps are not self-priming. The
suction pump must be run until the water flows from the clear water hose.
The backflushing pump can be monitored only indirectly in the system. For this purpose, it is activated in
test mode for one minute. Thereafter revert back to suction pump. If the suction pump requires some
time to refill the backflushing tank then, before the permeate flows out of the clear water hose, it can be
noted that the back flushing pump is working.
The system is ready to use after termination of test mode.
