ABSTRACT:
Apparatus for selectively separating matter between a first fluid and a second fluid through semi-permeable membranes. The apparatus comprises frame means defining first and second contact zones, each of which is in turn comprised of first and second contact chambers. A plurality of tubular semi-permeable membranes are disposed in each of the contact chambers. Each of the tubular membranes has an inlet end and an outlet end, and is adapted to conduct a least a portion of a first fluid from the inlet end to the outlet end. Barrier means are provided between the first contact zone and the second contact zone for preventing fluid communication therebetween. Fluid communication means are provided in each of the contact zones for providing fluid communication between the first contact chamber and the second contact chamber of each of the contact zones so that fluid in each of the contact zones flows substantially throughout both the first and second contact chambers thereof around a plurality of tubular membranes. Inlet means are provided for the second fluid for distributing the second fluid between the first and second contact zones and for introducing a portion of the second fluid into each of the contact zones. Outlet means are provided for withdrawing the second fluid from each of the contact zones after the second fluid is conducted substantially throughout the first and second contact chambers. Sealing means are provided for sealing the plurality of tubular membranes from the contact chambers so that there is no contact between the first fluid and the second fluid.
