A Drum Filter is a type of mechanical filter used for liquid-solid separation in various industries, such as wastewater treatment, mining, food and beverage processing, and chemical manufacturing. It consists of a rotating drum, typically made of stainless steel or plastic, which is covered with a filter medium, such as cloth, mesh, or perforated plates. The Drum Filter is immersed in the liquid to be filtered, and as it rotates, the filter medium captures solid particles while allowing the liquid to pass through.
