Rotary Vacuum Drum Filter

The process cycle of RVDF is continuous, As the drum rotates partially submerged in the slurry, vacuum draws liquid through the filter medium on the drum surface which retains the solids. The vacuum pulls air or gas through the cake and continuous to remove liquid as the drum rotates, different discharge methods can be selected. Should the filtered cake be washed, wash liquors will be introduced with spray pipes or suspended wash belts. The wash liquor can be separated from the mother liquor.
