Membrane technology

MBR (Membrane Bioreactor)

Space problems, increased effluent limits, corporate sustainability goals or the desire to reuse wastewater for irrigation systems and the associated conservation of natural resources are reasons for using membrane bioreactors in wastewater treatment plants.

The treated wastewater from the activated sludge tank of the wastewater treatment plant is separated from any solids by membranes installed in tanks. The pore size of the membranes can be selected depending on the desired clear water quality. The finer the membrane, the higher the quality. It is possible to remove particles with a size of a few nanometres from the water. With nanofiltration or reverse osmosis, clear water can be treated to drinking water quality.

Another advantage of the MBR process is the possibility to operate the activated sludge tank with 2 to 3 times higher activated sludge concentrations compared to conventional activated sludge processes without membrane technology. This significantly increases the cleaning capacity of the basins, which results in a reduction in the size of the basins and a concomitant reduction in the space required. Perfect for locations where every square metre of free space is precious.

Ideal for our customers who have high demands on the effluent quality with simultaneous minimisation of the space requirement.
