This research is to investigate an innovative new technology for wastewater using a combined process of biologically active powdered carbon and microfiltration(BAPC-MF). The continuous flwo bench scale BAPC-MF system studies were conducted for the treatment of wastewater. It was demonstrated that the BAPC-MF system has several advantages compared to conventional treatment process in terms of effciency and operational costs. The BAPC-MF system was optimized regard to several parameters includign emebrane flux rate, permeate quality, carbon concentration, sludge age and biomass concentration. It was found that the BAPC-MF system is significantly more effective than the PACT process in treating wastewater.
