The performance of sewage treatment at 25�C in removal efficiency, biogas production, and membrane fouling was studied using a submerged anaerobic membrane reactor (SAnMBR). Average 89% methanogenic degradation efficiency aswell as 90%, 94% and 96% removal of total chemical oxygen demand, biochemical oxygen demand, and nonionic surfactant were obtained. Results suggested that SAnMBR can effectively decouple organic degradation and nutrients disposal, and reserve all the N2 and P in the effluent for further possible recovery. Small biomass yields of 0.11 g mixed liquor volatile suspended solids/gCOD were achieved, coupled to excellent CH4 production efficiencies of 0.338 NLCH4/gCOD,making SAnMBR an attractive technology characterized by low excess sludge production and high bioenergy recovery. Also, results revelaed the SAnMBR appeared to have the potential to bear a high food-to-microorganism ratio without any inhibition effect. Pore blocking dominated the membrane fouling behaviour at a relative long hydraulic retention time.
