A submerged anaerobic membrane bioreactor (SAnMBR) was used in the treatment of real municipal wastewater at operation temperatures ranging from 15 °C to 25 and hydraulic retention time (HRT) 6 h. The process evaluated terms organic removal efficiency, biogas production, sludge growth filtration. During long-term operation, SAnMBR achieved chemical oxygen demand efficiencies about 90% with a lo...
