Drum-type screens, also known as micro-strainers, are purification devices that achieve solid-liquid separation by intercepting solid particles in wastewater. They use microporous screens with 80-200 meshes per square inch fixed on a drum-type filtration equipment. Drum screens are used for the primary filtration of raw water to remove large particles of sediment, suspended algae, and other particulates, or for the initial coarse filtration stage in closed-loop purification systems.
