The automatic filter presses with greater than 678 cubic feet of volume and 10,764 square feet of filtration area are being applied in varied minerals and other applications. The filters can operate up to 15 bar filtration pressure and are available with both recessed and membrane filter chambers. The large single filter capacity is advantageous in minerals tailings dewatering applications where multiple filters are required to dewater large volumes of solids. Utilizing this pressure filtration technology, the filters maximize the recovery of water for re-use in the process. The resulting cake can be dry stacked reducing the need for tailings ponds and promoting ongoing reclamation.
