Abstract
An assembly for removing grit from a fluid comprising a tank with a fluid inlet into the tank and a discharge from the tank. A flow directing assembly is positioned in the tank adjacent the fluid inlet and includes a substantially U-shaped surface opposite the fluid inlet such that fluid entering the tank through the inlet is caused to have a reversed flow in a direction more than 90 degrees from an inlet flow direction. At least one embodiment of the assembly further comprises a baffle positioned proximate the tank discharge to control flow adjacent the discharge. Yet a further embodiment of the assembly includes a screw conveyor positioned in a trough of the tank and a baffle is positioned proximate the trough to minimize fluid flow velocity adjacent to the screw conveyor.
