2.1 Functional Description
Fig.: Example installation layout of AQUALOOP Greywater Recycling System
The greywater (1) from the bathroom (bath tub, shower, basins) and washing machine outlets is first
filtered by the pre-filter (2) and then enters the bioreactor (3). In case the bioreactor is full of water, the
greywater overflows into the sewer (11) via the filter overflow. If the water level has reached its maximum
capacity, the water overflows through the integrated skimmer on the pre-filter to remove the floating
debris (foam, grease, oil) from the surface of the water. The sludge pump (4) is used for regular sludge
removal of the system. The sludge pump outlet is routed into the sewer via the overflow.
In the bioreactor, the greywater is treated biologically (ae growth bodies). The aeration is provided
by the blower (5) and regulated by the AQUALOOP controller (6). The aeration pipe is connected on the
bottom side with the membrane station (7). The aeration has two functions: Aeration for the biological
water treatment and for the cleaning of the membrane fibres through an air scour.
After biological treatment, the membrane station controller operates the ultra-filtration process where
clean water is pumped to the holding tank (8). Filtration transfer alternates between suction and backwash
to further keep the membranes clean.
The minimum level of the bioreactor is controlled by a level sensor. The filtration process is interrupted, if
the minimum level in the bioreactor is reached or if the maximum level in the holding tank is reached. The
bioreactor is ventilated by the vented greywater inlet pipe (1) or by a separate vent pipe.
