Good Rotary Drum Vacuum Filter 

The process cycle of the RDVF is continuous. Each revolution consist of cake formation, cake washing (if required), drying and cake discharge. As the drum rotates-partially submerged in the slurry-vacuum draws the liquid through the filter medium (cloth) on the drum surface which retains the solids. The vacuum pulls air (or gas) through the cake and continues to remove liquid as the drum rotates. If required, the cake can be washed prior to final drying ... and discharge. The filtrate and air flow through the internal filtrate pipes, through the rotary valve and into a vacuum receiver where the liquid is separated from the gas stream. Vacuum is normally developed by a liquid ring vacuum pump. The filtrate is usually removed from the receiver by a pump or barometric leg. Multiple receivers connected to the filter valve allow for the separation of mother liquor from the wash liquor, and…
