摘要: A sloped plate water clarifier is provided with multiple clarifying stages. Slurry enters a feeding and mixing passageway that contains chemical flocculant in the form of polymer gel logs. Agitating drums provide controlled slurry flocculant. At end flows over static screen separates useable process product from solid refuse. The passing through into settling tank containing plates arranged three ascending stages, uppermost stage being angularly adjustable. As rises inside tank, allow suspended solids to settle eventually accumulate on bottom for periodic removal, including as an alternative by venturi pump. clarified exits spillway at top tank.
