ABSTRACT:
A filter press utilizes a continuous loop tube having at least one longitudinal segment made of filter media and an insert frame encapsulated within the tube. The tube is driven by a roller chain/link chain combination such that the tube is repeatedly inverted and drawn through the frame. A liquid/solid slurry is introduced at one end of the tube and passes through the frame therewith wherein hydrostatic and hydraulic forces urge the liquid outwardly through the filter media which retain the solids until they have passed through the restricted volume of the frame. No lateral seals are required in as much as the tube completely encircles the slurry.
