Tighter discharge regulations, urbanization and increased water recycling efforts have made membrane bioreactors (MBR) the leading innovation in wastewater treatment compared to conventional activated sludge.

With MBR technology, the clarifier is replaced by a physical barrier – the WESHTER WTM membrane module. This physical barrier enables the MBR to operate at higher MLSS levels than secondary clarifers, resulting in a smaller overall footprint.WESHTER WTM membrane modules operate within the ultrafiltration spectrum, producing high capacities of quality effluent at consistent flows.

WESHTER WTM utilizes a unique membrane laminate that offers the best of the two predominant module configurations on the market (hollow fiber and plate & frame) without any of their inherent disadvantages. The self-supporting membrane sheet is just 2 mm thick, resulting in an extremely high packing density and very low specific energy consumption. The membrane laminate also has a self-healing mechanism. In case of damage to the membrane, the spacer material in between the WESHTER WTM membrane laminate sheets allows for a sealing of the damage through use of the biomass in the system. Even after a severe detraction of the membrane laminate, solids and bacteria are still rejected by the WESHTER WTM module.
