ABSTRACT:
A filtration or diffusion cell, consisting of adjacent facing support plates and cut diaphragm sections of a semi-permeable diaphragm, for the treating fluids. The support plates are sealed by stringlike or bandlike sealing elements for the separate flow conduction of the fluids. Support plates are provided with channel grooves, for holding the sealing elements. The channel grooves are open toward the plate plane and are provided with perforations through which a sealing material inserted in a flowable state and solidified in the grooves. Several support plates are connected by the sealing material to form a plate holder-like unit, and form seals for separate flow conduction. The support plates are square-shaped, and the front side and the back side of the cut diaphragm sections are subjected to crosswise flow of the fluid. The cut diaphragm sections are supported by grooves and groove crests extending in flow direction of the support plates. The grooves are provided with longitudinally spaced passages leading to the opposite side of the support plates. Flow barriers crossing the grooves under an angle of about 45.degree. bring about a uniform overflowing of the diaphragm surfaces and prevent shortcuts.
