The objective of this study was to investigate the effect of fermented food waste as an external carbon source on nutrient removal in a membrane coupled sequencing batch reactor treating municipal wastewater with low ratio of carbon to nitrogen sources (C/N ratio). The operation pressure lower than critical permeable flux was maintained to minimize the membrane contamination which was defect of membrane coupled sequencing batch reactor. The removal efficiencies of NH4(+)-N and PO4(3)-P were increased by 79%~98% and 35%~80% after adding the fermented food waste. Therefore, the efficient nutrients removal process can be established when fermented food waste and wastewater with low C/N ratio were simultaneously fed into the membrane coupled sequencing batch reactor.
