Abstract:

The ever-expanding world-wide application of biological nutrient removal (BNR) technology is generating a greater appreciation for the performance of BNR processes under different operating conditions. This paper examines the effects of high process temperature on the biological phosphorus and nitrogen removal mechanisms and the sludge settling properties in BNR activated sludge processes. These effects are illustrated with data from three full-scale BNR facilities in which enhanced biological phosphorus removal (EBPR) failed, but nitrification and denitrification were maintained at mixed liquor temperatures of approximately 30°C.
