| Abstract | In this research secondary oxidation ponds, at pilot scale, were investigated for the removal of nitrogen in the reclamation of potable water from wastewater. The parameters studied were pond depth, detention time and level of nutrient supplementation (iron and phosphorus). These parameters were optimized with respect to nitrogen removal efficiency, and the following optimum conditions were obtained: 25 cm pond depth, 2-day detention time , 5 mg/l of phosphorus and 2 mg/l of iron supplementation. The average effluent total-N and ammonia-nitrogen were found to be 5.9 mg/l and 3.45 mg/l respectively, corresponding to average removal efficiencies of 73.3% and 83.1%. Equation correlating the influent and effluent NH3-N, Org-N and total-N, and, influent NH3-N and algal-N produced were also formulated by regression equations. A Kinetic model for NH3-N uptake was developed for the system. |
