Rotary drum screens, also called drum filters or rotary screens, have two types: internal and external feed. They separate solid particles from liquids, widely used in industries for solid-liquid separation and wastewater treatment.

As the drum rotates, liquid passes through the screen, retaining solid particles. A cleaning device ensures continuous equipment operation by removing accumulated solids. Filtration efficiency depends on the screen surface aperture. Rotary drum filters offer efficient solid-liquid separation, continuous operation, and self-cleaning, making them ideal for various industries.

These filters are used in municipal and industrial wastewater treatment, process water filtration, food and beverage processing, and the pulp and paper industry. With features like high flow capacity, adjustable filtration precision, and easy maintenance, rotary drum filters play a vital role in improving efficiency, reducing costs, and ensuring reliable filtration performance.
