Studies were undertaken to examine the efficiency of nitrification, denitrification and phosphorus removal in the biological treatment at Changi Water Reclamation Plant (CWRP). Samples were collected and tested over a period of three months. NH3-N is greatly reduced in the aerobic zone (54- 89%), considerable denitrification (~64-92%) is observed across the anoxic zones. The overall P removal is ~58% with P release in the anoxic zone (10-22%), P uptake in the aerobic zone (33-47%).
