Description:

Filter presses in principal are pressure filters, wherein a pack comprising of a series of plates and frames (Polypropylene, Cast Iron or Aluminum) or chamber plates (1) (Recessed plates) is compressed between a fixed head (4) on one end and one movable bulk head (3) on the other end, that the movable bulk head is contacted to a hydraulic jack (8).
Filter pack is supported on two parallel tie bars (2)

which are stretched between the fixed end (4) and the free end (3).

The filter press also consists of a skeleton to support the filter plates and a closure mechanism (7) to provide the necessary force on the sealing faces of the plates to counteract the applied force of filtration.

Filter presses are loaded with slurry before completing a filtering cycle and producing a batch of solid filtered material, called the filter “cake” (5). The solid is removed, the press re-loaded with slurry and the filtering cycle repeated. A filter press uses increased pressure to maximize the rate of filtration and produce a final filter cake with a low water content.
