The filtration area of one technical module is 105 m2. 3 modules are assembled to form a row. The hollow fiber membranes are stretched between 2 permeate collection pipes with a specified over length in order to allow them to swing in the up flowing mixture of air and biomass.
The aeration device below the membranes enhances the turbulence and consequently the scrubbing effect on the membrane surface.
An intermittent aeration mode and a backwash with clean permeate are possible.
The trans-membrane pressure of up to 0.6 bar controls the filtration quantity and is provided either by geodetic height difference or by a suction pump.
