Episode 43 : DESIGN of Rotary Vacuum Drum Filter. Rotary vacuum drum filter (RVDF) is one of the oldest filters used in the industrial liquid-solids separation .A rotary vacuum filter consists of a large rotating drum covered by a cloth. The drum is partially immersed in liquid/solids slurry with approximately up to (25-75) % of the screen area.

The Rotary Vacuum Filter is made up of a large drum with tiny holes rotating in a vat containing the final treated wastewater. It is often used to dewater and extract out the waste sludge so that a clear discharge can be obtained. What is different between this compared to other unit of operations is that vacuum is continuously applied to the system pushing the liquid through a filter media so ...
