Abstract: The clarifier of the present invention includes a tank, an influent pier, and a FEDWA. The tank that includes a bottom and a wall. The influent pier projects upwardly from the bottom of the tank along an axis. The influent pier includes ports that direct flow of the solution outwardly from the influent pier. The FEDWA separates the flow of the solution that is discharged by the ports and that flows into the tank. The separated flow of the solution includes a first flow portion that is directed in a first direction that is generally tangential with respect to the axis of the influent pier, a second flow portion that is directed in a second direction that is opposite to the first direction of the first flow portion, and a third flow portion that is directed in a third direction toward the axis.

Abstract: The present invention is directed to a sludge collector for use with a circular clarifier. The circular clarifier includes a tank that has a bottom and a wall that extends upwardly from the bottom of the tank. The tank is configured to contain a solution and allow sludge to settle from the solution to the bottom of the tank. The sludge collector includes a withdrawal manifold, a scraper assembly, and an entrapment plate. The withdrawal manifold is located at the bottom of the tank. The scraper assembly extends from the withdrawal manifold toward the wall of the tank and moves the settled sludge toward the withdrawal manifold. The entrapment plate extends between the withdrawal manifold and the scraper assembly to trap sludge between the withdrawal manifold and the scraper assembly and funnels the trapped sludge into the withdrawal manifold.
