Abstract

1334052 Treating sewage DORR-OLIVER Inc 21 Aug 1970 [22 Aug 1969] 40347/70 Heading C1C In a process for precipitating phosphates from an aqueous liquid waste in which there is formed an aqueous effluent and a phosphorus containing sludge lime is mixed with recycled sludge and/or a portion of raw feed to give an alkaline mixture having a predetermined pH of 10À5 or more and the alkaline mixture is either mixed with raw feed or the remainder thereof to give a low predetermined residual phosphate content to the aqueous effluent. Flocculation aids may be present.
