A rotary drum screen filter is a mechanical filtration device designed to remove coarse and fine solids from wastewater. It consists of a rotating cylindrical drum constructed from either wedge wire or perforated steel, through which water flows while solid particles are captured on the outer surface. This screening process allows for continuous operation, where solids are collected and discharged while filtered water passes through to the next treatment stage. The system is equipped with automatic self-cleaning mechanisms that reduce the need for manual maintenance and prevent clogging. Why Rotary Drum Screens Are Used in Wastewater Treatment Plants Rotary drum screens serve as the first line of defense in wastewater treatment. Their main function is to separate non-biodegradable solids, such as plastics, rags, hair, and sludge particles before the water enters biological or chemical treatment zones. This pre-treatment screening significantly reduces the load on aeration tanks, cla...
