Tighter discharge regulations, urbanization, and increased water recycling efforts have made membrane bioreactors (MBR) the leading innovation With MBR technology, the clarifier is replaced by a physical barrier – the BIO-CEL® membrane module. This physical barrier enables the MBR to operate at higher MLSS levels than secondary clarifiers, resulting in a smaller overall footprint. BIO-CEL membrane modules operate within the ultrafiltration spectrum, producing high capacities of quality effluent at consistent flows.  This creates a distinct advantage in wastewater treatment compared to conventional activated sludge.

BIO-CEL 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 BIO-CEL 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 BIO-CEL.

The modules´ open channel design reliably prevent the deposition of sludge and fiber accumulation during the continuous crossflow operating process. The self-supporting structure of the membrane module enables frame-free installation, eliminating blockages around the external boundaries of each component. The membrane module is configured to allow for consistent permeate flow and a highly effective backflush over the entire membrane surface. In summary, BIO-CEL® MBR offers high packing density with optimal separation.
