A comparative study between two biological nutrient removal (BNR) systems i.e. one employing membranes and the other conventional A2O system was conducted at the hydraulic retention time (HRT) and solids retention time (SRT) of 8 h and 10 d respectively using synthetic wastewater (SWW) and municipal wastewater (MWW) which contains 30% of the volatile fatty acid (VFA) of the SWW. Achieved COD, N and P removal efficiencies for the MBR were 95-98, 72-75 and 70-91%, respectively, compared to 95-98, 70-76 and 70-77% for the A2O. It was confirmed that the primary factor governing P removal is VFA concentration. Accordingly, the contribution of denitrifying phosphorus accumulating organisms (DPAOs) to P removal was greatly hampered. However, the impact of an intermediate clarifier P removal in the MBR was significant for both SWW and MWW runs.
