WASTEWATER TREATMENT PLANTS: DESIGN AND …
The first unit operation generally encountered in wastewater treatment plants is screening. Screening removes larger materials and coarse solids from raw wastewater metals to prevent damage and clogging of downstream equipment, piping, and appurtenances. Two types of screening processes: • Manual. • Automated.
