It is recommended that the sewerage overflow drainage is vented externally to prevent any unpleasant
odors.
If the system is installed below the backwater level*, then the overflow must be routed to a pumping
station, so that the water above the backwater level can be pumped to the drainage via a tube loop. Look
for a pumping system with sufficiently large pumping characteristics.
*Backwater level:
The level up to which an overflowing drainage network can be refilled. It usually corresponds to the
respective street level. Check with your local building authorities.
Connection of the blower
The blower pipe is connected to the blower connetion of the membrane station (9)
The electrical cable ist connected with the control unit
The pressure sensor (4) is mounted in the blower pipe. The sensor cable is connected with the controll
unit.
Membrane station
The clear water hose is connected to the back flushing tank (7) and connection device (6).
Note:
The system is designed for indoor restricted urban water use, to supply water for consumers such as
toilet and urinal flushing
and for outdoor irrigation use. Cross connections to the public water supply are
strictly prohibited!
The electrical cables from suction and backflush pumps are connected to the control unit (Chap. 6.1)
Floating switch
The floating switch (8) in the bioreactor indicates the minimum water level (700 mm).
Note: The distance between float switch and counter weight must be 100 mm!
Permeat connection device
The connection device (6) is connected with the permeate hose from the back flush tank.
The pipe outlet is protected with a non-return valve.
The permeate outlet pipe is protected against back flush and is marked
with a non-potable sign.
