Trevor Sparks, George Chase, in Filters and Filtration Handbook (Sixth Edition), 2016. 2.8.2 Stacked disc filters. Stacked disc filters are similar to the edge filter in appearance, in that they have an array of disc-shaped components held on a central core. The stacked disc filters differ however in that the discs are actually hollow, with filter media over the faces of the disc.

A Rotary Vacuum Filter Drum consists of a drum rotating in a tub of liquid to be filtered.. The technique is well suited to slurries, and liquids with a high solid content, which could clog other forms of filter.The drum is pre-coated with a filter aid, typically of diatomaceous earth (DE) or Perlite.After pre-coat has been applied, the liquid to be filtered is sent to the tub below the drum.

Structure and Principle. Horizontal belt filter is unique vacuum filter which is specialized in cake washing performance. Effective cake washing is realized because the filter can replace uniformly mother liquor in wet cake by cake washing liquid. As uniform cake layer are formed continuously, uneven washing can be prevented.
