"SYSTEM FOR PURIFICATION OF PHOSPHATE-CONTAINING SEWAGE" Abstract of the Disclosure For improvement of the phosphate redissolution taking place under anaerobic conditions, the treatment is conducted under anaerobic conditions, preferably in a settling tank, into which unsettled raw sewage and a return sludge from the secondary settling tank are introduced. The sludge retention time of the return sludge is generally over 5 hours, preferably 10-24 hours. In any case, the sludge detection time exceeds the hydraulic detection time. The new process can be performed by using most existing plants with relative small investment expendi- tures and provides a phosphorus elimination on the order of magnitude of 90%.
