A Rotary Vacuum Drum Filter (RVDF) is a continuous filtration device widely used in solid-liquid separation processes. It consists of a rotating drum partially submerged in slurry, with vacuum applied inside the drum to draw liquid through the filter medium, leaving the solids as a cake on the surface. The drum rotates slowly, and the filter cake is removed by various discharge mechanisms such as knife, scraper, or belt.
