Screening and Grit Removal - EPA

In smaller plants, grit chambers are often cleaned manually. Hydrocyclone. Hydrocyclone systems are typically used to separate grit from organics in grit slurries or to remove grit from primary sludge. Hydrocyclones are sometimes used to remove grit and suspended solids directly from wastewater flow by pumping at a head.
