Pilot scale studies on enhanced phosphorus removal in a single-stage activated sludge treatment plant

Enhanced biological phosphorus removal from domestic sewage was investigated in a single-stage activated sludge treatment plant with pre-denitrification operated in a continuous process. In 10 different experimental periods the influence of varying composition of the influent, varying systems of the...

description Enhanced biological phosphorus removal from domestic sewage was investigated in a single-stage activated sludge treatment plant with pre-denitrification operated in a continuous process. In 10 different experimental periods the influence of varying composition of the influent, varying systems of the pilot scale unit (with and without anaerobic basin), varying retention times in the different basins and varying sludge loads were investigated. Results of the experiments can be summarized as follows: the nutrient situation and especially the P/BOD5 and N/BOD5 ratios, retention time in the final clarifier, and organic sludge load plus the desired degree of nitrification have essential influence on the process and P removal efficiency. The conclusions for the pilot scale process are discussed.
