Performance of cellulose triacetate immobilized activated sludge was tested with sequencing batch reactor in this study. By operating the reactor in a mode to develop the characteristics of SBR, the immobilized activated sludge offered a high efficiency in the biological nutrient removal. The 98% COD removal, 96% total nitrogen removal, and 85% of phosphorus removal were achieved in the SBR process with synthetic wastewater as influent. Effluent was clear without settling. Phenomenon of phosphorus release, nitrification, denitrification, aerated denitrification were observed in this study.
