9.3 Starting the bio reactor
Following settings values are set as follows for the filtration process (
Example of an AQUALOOP System
300L/day
:
Menu 1: Number of membranes: MEM = 1
Menu 2: Suction overflow: SO= 0 (weeks)
Menu 3: Sludge pump: SLP/t= 7 / 1 (days/min)
Menu 6: local Time: e.g. 14:16:31 hrs
Menu 7: Start time T1: e.g. T1 = 01:00 hrs
Menu 8: Start time T2: e.g. T2 = 13:00 hrs
Menu 10: Pump cycles: e.g. A1/A2 = 24 / 20
Menu 11: Blower time: Air ON / Air OFF: e.g. 5 / 5 (min/min)
Suction and back flush pump can be started and tested in the test mode. Please run the suction pump
until the water flows from the clear water device – this may take a few minutes to come through.
Note: If the minimum water level is reached (Br
min
-), the testing of the pump will be interrupted. The
tank will be filled up until the floating switch displays Br
min
+.
The back flush 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 back flush tank then, before the permeate flows out of the clear water hose, it can be
noted that the back flushing pump is in fact working.
The system is ready to use after termination of test mode.

The device will continue to work normally even during the holiday (vacant standing) period. This means
that a separate holiday setting is not needed. If the bio reactor runs for a longer period without any
incoming grey water then this may decrease the efficiency of biological treatment.
In case of further expected incoming grey water, the start-up phase (where the treated water is sent to
sewer for 3 weeks) must be performed again (s. Chap. 9.2).
Note:
An error message will appear after 21 days of stagnancy of the bio reactor
The permeate flow reduces to a lower level during the working time of the membranes.
In case the permeate flow drop down to a lower value the filtration cycle A1/A2 can be increased at all
times.
Note: The filtrated permeate can be extracted for sampling via the connection device.
