What is the primary purpose of screening in wastewater treatment?

The primary purpose of screening in wastewater treatment is to remove large solids and debris. This initial process is crucial because it protects downstream equipment and processes from damage or clogging. By eliminating oversized materials such as plastics, leaves, and other large objects, screening ensures that the treatment system operates efficiently. It helps maintain flow rates and reduces maintenance needs by preventing blockages in pumps and pipes.

Enhancing the biological treatment process involves further treatment steps that take place after screening. Monitoring water quality and providing odor control are important aspects of wastewater management, but they occur at different stages and are not the primary focus of the screening process itself. Screening is fundamentally about preparing the wastewater for subsequent treatment stages by ensuring that it is free from large unwanted materials.
