Anaerobic Membrane bioreactors 

Industrial wastewater with high organic loads can be a potential and valuable source of energy if treated anaerobically.  Anaerobic membrane bioreactor (AnMBR) systems combine anaerobic digestion with physical separation via membrane filtration, resulting in maximum organic load removal. This technology produces superior effluent quality when compared to other anaerobic technologies available on the market. It offers several additional advantages such as higher treatment capacity, smaller footprint and low sludge production. Additionally, the methane rich in biogas, can be used as a renewable source of power or heat.

AnMBR is ideal for the treatment of wastewater streams or slurries with high concentrations of organics, solids, fat, oil, and grease. The ultrafiltration membrane (UF) ensures complete solids retention, efficient system operation and process stability at all time. The AnMBR biomass has a different consistency compared to the aerobic MBR and contains more single cells. Membrane fouling is mainly caused by deposits and accumulation of micro-organisms, colloids, solutes and cell debris on the membrane surface. Therefore, the main challenge in this process is to control fouling potential via low-fouling membranes, optimal operational conditions and advanced cleaning protocols. Traditional anaerobic systems can be easily upgraded to an AnMBR configuration in order to increase loading capacity, and improve performance and effluent quality.
