In the wastewater treatment process, rotary drum screens are used as a pre-treatment method to separate solids, including debris, grit, algae, and sludge, from liquids. When wastewater enters the drum, the waste passes through a screen mesh, which captures and retains the solids while the rest of the water flows through the screen.

A rotating drum is employed by the Internally Fed Drum Screens for Wastewater Treatment for providing effective fine screening for a varied range of materials with a simple and reliable design. A cylindrical screen is employed by the construction with perforated metal, wedge wire, or filter cloth along with a system.
The rotating drum continuously filters water, allowing smaller particles to pass through while retaining larger solids on the drum surface. Rotary drum screens play a crucial role in wastewater treatment plants by removing debris, solids, and other pollutants from the water before it is discharged or further treated. Rotary drum screens Advantages
The drum screen's internal hopper receives screenings that are flushed out by an end-pipe wash water nozzle to external troughing, providing an unimpeded flow out of the screen for dewatering.
