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.

Abstract: A process for cutting a moving strip to form a series of plates, such as battery plates, includes the initial step of transporting the strip past a rotary divider including a cutter having radial blades configured to cut the strip into the plates. The cutter further has a set of blades for cutting individual pieces from the strip, which pieces are not part of the plates. As the cutter blades cut the strip to form the plates and pieces, a vacuum system applies suction to draw the pieces cut from the strip inwardly into the cutter through holes in the cutter, and then out of the cutter. The holes are each located adjacent each one of the corresponding blades and are shaped and positioned to permit the cut-away piece to pass through. In a preferred embodiment, the vacuum system includes a pair of vacuum manifolds that apply suction at opposite ends of the cylindrical cutter. An apparatus for carrying out the foregoing process accordingly includes a rotary divider as described above provided with a vacuum system.
