The Hydraulic Retention Time (HRT) for the reactor was 3 days whereas the Solids Retention Time (SRT) was kept 100 days. The Organic Loading Rate (OLR) in the reactor was maintained at 1.06 kg COD/m3.d. The total COD removal efficiency was achieved higher than 98%, at operating conditions. The acclimatization and stabilization of reactor was achieved in around 2 months. At steady state condition a total reduction in COD of 98.5%, 99% and 99.5% occurred in suspended growth, attached growth, and membrane system respectively. During the entire operation, the membrane was required to be physically cleaned once after 30 days of operation. Hence Anaerobic Hybrid Membrane Bioreactor can be successfully used to treat high strength wastewater. Copyright@ International Science Community Association
