ABSTRACT:
Apparatus for selectively separating matter between a first fluid and a second fluid through semi-permeable membranes. The apparatus comprises a plurality of elongated frame assemblies, each of which define an elongated contact chamber for the second fluid. A plurality of tubular semi-permeable membrane for the first fluid are disposed in each of the contact chambers of the frame assemblies. The plurality of elongated frame assemblies are stacked together with the elongated contact chambers thereof being in side by side relationship. Fluid communication means are provided for the stacked frame assemblies for providing fluid communication between the contact chambers of the frame assemblies through which the second fluid is adapted to be conducted. Sealing means are provided for sealing the tubular semi-permeable membranes from the contact chambers so that there is no contact between the first and second fluids. Further, a pair of cover plates are provided for the stacked frame assemblies and a first and a second end fitting are provided for the ends of the stacked frame assemblies. At least one of the end fittings includes means for clamping the frame assemblies between the pair of cover plates to hold the frame assemblies together. Inlet and outlet means are provided for the first fluid for introducing the first fluid into the tubular semi-permeable membranes and for withdrawing the first fluid therefrom, and inlet and outlet means are provided for the second fluid for introducing the second fluid into at least one of the contact chambers and for withdrawing the second fluid therefrom after the second fluid has been conducted substantially throughout the contact chambers of the stacked frame assemblies around the tubular semi-permeable membranes to selectively separate the matter between the first and second fluids.
