HFR (High Flow Rate) Grit Washer

The high performance of the HFR Grit Washer is achieved by immediately redirecting the inlet stream to create predictable flow patterns which promote rapid separation and settling of solids. The heavy inorganic grit is forced to settle and in turn be conveyed by the screw discharge while lighter organics are carried over the front discharge weir to be returned to the treatment process flow. Dual adjustable weirs are standard.

The heart of the grit washer system is the specially designed interior baffle assembly. The compact flow redirecting inlet distribution assembly, diffusion and discharge plates make up the baffle assembly and are fully removable from the unit for ease of maintenance and access to the screw.
