PROCEDIMENTO ED APPARECCHIO DI SEPARAZIONE LIQUIDO-SOLIDI

摘要

A flow of liquid containing suspended solid particles enters a top inlet of a setting tank of a liquid-solid separator. The tank is of such dimensions that the liquid flows in a nonturbulent flow path under a lengthwise partition in the tank and through an outlet weir opening formed in the tank on a side opposite the inlet. From the outlet the liquid may be returned for further use in a process. Under the influence of gravity, a substantial portion of the solids in the flow slowly settles downward and collects to form a cake on a movable collection means serving as part of a bottom of the tank. Periodically the movable collection means is advanced toward a discharge point located exterior to the tank for convenient disposal of the solids collected on the movable surface.
