Abstract
A membrane filter press has a series of filter plates having an imperforate pipped membrane mounted on each side or one side thereof. Inlet ports are provided with a cantilevered retainer which support adjacent portions of the membrane when the membrane is expanded to effect a squeezing of filter cake deposited on filter media carried by pips on the membrane. The retainer may be circular in the case of a center inlet port or linear in the case of a corner inlet port. Corner outlet ports are provided in the filter plate, with the plate having a linear collection groove juxtaposed to an outer edge portion of the membrane so that filtrate flow from around the membrane pips to the collection groove and by passages only in the plate are conveyed to an outlet port. A beaded membrane rib enhances the connection of the membrane in a filter plate groove at a position adjacent to the plate seal face of adjoining filter plates.
