Screens play a crucial role in the wastewater treatment process by removing coarse, medium, and fine solids from water and wastewater treatment facilities. They prevent damage and clogging of downstream equipment, piping, and appurtenances. The types of screens used include coarse screens for large solids and fine screens for smaller materials that may cause
operation and maintenance problems. Proper screening ensures the efficient separation of suspended solids and contributes to the overall quality of the treated water.
