The internally fed drum screen filter is an advanced filtration device designed for efficient separation of solids from liquids. The system consists of a cylindrical drum, typically constructed from stainless steel, equipped with a continuous mesh screen. This drum is partially submerged in the liquid being filtered.

As the liquid enters the drum, it flows through an inlet at the centre, pushing the incoming material against the mesh screen. Solid particles are trapped on the screen's surface while cleaner liquid passes through, moving outward. The rotation of the drum is carefully controlled and often integrated with a scrapping mechanism, allowing accumulated solids to be removed continuously.

This separation process is highly effective due to the large surface area of the drum and the design that facilitates gravitational settling. Applications for internally fed drum screens are diverse, ranging from wastewater treatment to process water filtration, where they help maintain optimal system performance. The innovation behind this filter ensures minimal maintenance and efficient operation, appealing to various industries seeking reliable and sustainable solutions for solid-liquid separation.
