In this study, the submerged type membrane separation process was coupled to a sequencing batch reactor (SBR) which is one of the biological nutrient removal process and named it submerged membrane-sequencing batch reactor (SM-SBR). One experiment was conducted to investigate the operating schedule on transmembrane pressure, the other experiment were conducted to investigate that on organic and nutrient removal. The result when HRT 24hr(8hr/cycle) of SM-SBR in the experiment was showed the best removal efficiency of nitrogen and phosphorus.
