ABSTRACT:
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 in the passageway provide controlled mixing of the slurry with the flocculant. At the end of the passageway the slurry flows over a static screen that separates the useable process product from solid refuse. The slurry passing through the screen flows into a settling tank containing sloped plates arranged in three ascending stages, with the plates in the uppermost stage being angularly adjustable. As the slurry rises inside the tank, the sloped plates allow the suspended solids in the slurry to settle and eventually accumulate on the tank bottom for periodic removal, including as an alternative by a venturi pump. The clarified water exits a spillway at the top of the tank.
