A pair of membrane ultrafiltration cells are mounted one on each of the front and back surfaces of a central bidirectional manifold having an exit and an entrance conduit connector on the same side wall of the manifold. The manifold takes fluid to be filtered from a source through a conduit connector for full flow delivery to each filter cell and collects filtered fluid from each cell to be dispensed through a further connector. Plural manifolds may be connected to each other in a filter system for greatly increased filtering capacity.

Bidirectional ultrafiltration apparatus

A filtration apparatus including a filtration module having an axially stacked plurality of filter membrane sheets with the module defining a stack of fluid flow chambers having multi-edged perimeters and disposed on opposite sides of and substantially coextensive with each membrane sheet. Also defined by the module are a plurality of feed passages communicating with alternating ones of the chambers adjacent first axially aligned edges thereof, a plurality of retentate passages communicating with the alternating chambers adjacent to second axially aligned edges thereof opposite to the first edges, and a plurality of filtrate passage means communicating with other ones of the chambers between the alternating ones thereof and with the filtrate passage means entering the other chambers adjacent to either the first or second aligned edges. Also included in the apparatus are a base frame and a pair of parallel plates supported by the frame and movable thereon relative to each other in directions normal thereto. The module is retained between the parallel plates with the direction of movement thereof aligned with the axis of the membrane sheets and one of the plates defines a first channel substantially parallel to and axially aligned with the first edges, a second channel substantially parallel to and axially aligned with the second edges, and a third channel means including one portion substantially parallel to either of the first and second edges and another portion transverse thereto and extending a distance therebetween.

Ultrafiltration apparatus

A filter device including a unitary cell for receiving a fluid to be filtered and comprising a receptacle portion with an open end; a base portion defining an outlet and bonded to and closing an opposite end of the receptacle portion; and a filter membrane portion disposed between the open end and the outlet, the membrane portion being supported by the base portion and bonded between the base and receptacle portions. Also included are a cover removably engageable with the receptacle portion to close the open end; a seal disposed between the cover and the receptacle portion; a latch mechanism for producing a hermetic seal between the cover, the receptacle portion and the seal; an inlet providing for the receptacle portion an inlet for pressurized fluid; and a stirrer disposed within the receptacle portion and activatable to stir the fluid content thereof.
