Technical details
Thanks to its tried and tested design, Biosep™ offers a highly compact water treatment solution, enabling the treatment to be carried out using high concentrations of biomass (8 to 15 g SS/l).
Operating principle
Biosep™ uses an aeration tank and a membrane system where membranes are located and grouped into modules. These modules may be directly immersed in the aerated tank or in a separate basin.
After pre-treatment (e.g. screening), raw water flows into the aerated biological tank where carbon, nitrogen and phosphorus-containing pollution is removed.
Membrane filtration then separates the purified water from the activated sludge: the treated water is drawn off using a low-pressure pump. The sludge retained by the membrane create a sludge cake outsite the membrane surface. The excess sludge is directly removed from the biological tank for dewatering.
Maintaining filtration performance is the key point to the process; this is based on different automated functions : backwash, air injection and chemical cleaning.
An optimized and simplified treatment line
By replacing the conventional clarification stage, membrane separation does away with the limitations surrounding sludge settling. As a result, the treatment line is greatly simplified and the treatment performance optimized.
Conventional activated sludge versus Biosep™

3D view of Biosep™
A physical barrier at the system's core
The filtration membranes (flat sheet membranes or organic hollow fibers) are placed in direct contact with the biomass responsible for the biological treatment of the pollution.
Very good mechanical resistance
Produces treated water which is of an excellent bacteriological quality
