The purpose of the Preliminary Treatment is to remove most of the non-soluble solids physically to reduce the pollutant loads and to protect all the subsequent steps in the treatment plant and also to protect raw water recovery and more generally to remove anything that could hamper subsequent treatment processes. Depending on the quality of the water to be treated, several processes could be required. Screens are used to retain large solids that may be present in wastewater so as to prevent them from entering moving devices (e.g., pumps) and wastewater treatment units.
