Enhanced biological phosphorus removal (EBPR) is not always successfully achieved in activated-sludge processes by anaerobic-aerobic operation. It has been reported that the deterioration of EBPR has been caused by domination of glycogen-accumulating organisms (GAOs) in microbial sludge. After repeated operation of a sequencing batch reactor (SBR) supplied with acetate as a sole carbon source, it was found that an operational variable, pH, could be a tool to control the competition between GAOs… CONTINUE READING
