The grey water (1) from bathroom (bath tub, shower, basins) and washing machine outflow is first
filtered by the pre-filter (3) and then enters the bio reactor (2). In case the bio reactor is full of water, the
grey water overflows directly into the sewer (6) via the filter overflow. The built in non-return valve
prevents the backflow of water, small animals and vermin from entering the tank. With each overflow of
the bioreactor the ground sediments are automatically extracted through the suction overflow (4) in the
AQUALOOP pre-filter. If the overflow has reached its maximum capacity, the water overflows through
the integrated skimmer and thereby cleans the floating debris (foam, grease, oil) from the surface of the
water. The sludge pump (5) is connected at a further pre-filter connection and is used for cleaning and
maintenance of the system. The sludge pumped outlet is directly routed into the sewer.
In the bio reactor the grey water is treated biologically (aeration/growth bodies). The aeration (9) is
produced by the Blower and regulated by the AQUALOOP control unit (10). The aeration pipe is
connected on the bottom side with the membrane cartridge (8). The aeration has two functions:
Aeration for the biological water treatment and for the cleaning of the membrane fibres themselves.
After the biological treatment the suction pump of the membrane station starts the microfiltration
process and the filtered, clear water is pumped to the clear water outlet. After each suction interval (15
min) the membrane is cleaned with a back flush sequence (15 sec).
The minimum level of the bio reactor is controlled by a floating level switch. The filtration process is
interrupted if the minimum is indicated. The bio reactor is ventilated via a ventilated grey water inlet
pipe (12) or a separate ventilation pipe.
