Abstract

1509481 Clarification of waste water PATERSON CANDY INTERNATIONAL Ltd 16 Dec 1976 [27 Jan 1976] 03045/76 Heading C1C Water is clarified by adding a coagulant to raw water to form a floc, concentrating the floc into a sludge, treating the sludge with a polyelectrolyte to convert the sludge to a fast-settling granular form, and feeding the treated sludge into incoming raw water so that the treated sludge collects a fresh covering of microfloc particles.
