Anaerobic membrane bioreactor
Anaerobic membrane bioreactors (AnMBRs) provide the benefits of low energy and chemical consumption, low sludge production, methane generation, and complete retention of biomass that allows for operation at extended solids residence times (SRTs), although full-scale implementation has been hampered by excessive fouling. There is a clear need to obtain information on the performance of AnMBRs treating real municipal wastewaters under conditions (e.g. temperature) representative of the real world. In addition, the relationships between SRT, HRT, performance and membrane fouling require further refinement to aid in sound engineering design. This project will undertake research to characterize AnMBR performance, investigate membrane foulants and develop operating strategies for minimizing fouling.
