Hydro International recently exhibited the Hydro GritCleanse fluidized-bed grit washing system at WEFTEC — a system which significantly reduces volatile solids content to produce cleaner and drier grit. Cutting volatile solids grit reduces weight, volume and water content, significantly reducing odors and saving money on landfill costs.
The system retains 95 percent of grit 106 microns and larger and discharges washed grit with less than 5 percent volatile solids, according to the company.
Flow is introduced tangentially into a conical clarifier, forcing the grit to contact the vessel walls, creating drag forces and establishing a rotary flow pattern. Incoming
