Apparatus for selective separation of matter through semi-permeable membranes

摘要

Apparatus for selective separation of matter between a first fluid and a second fluid through semi-permeable membranes. The apparatus comprises a plurality of separate frame assemblies each of which defines a separate contact chamber for the second fluid. A plurality of tubular semi-permeable membranes for the first fluid are supported in each of the contact chambers of the separate frame assemblies so that the second fluid will substantially surround the tubular membranes as it passes through such contact chambers. The plurality of frame assemblies are clamped together in stacked relationship so that the contact chambers are arranged in side by side relationship. Sealing means are provided for sealing the tubular membranes from the contact chambers so that there is no contact between the first fluid and the second fluid. Further, each of the frame assemblies is provided with communication means for providing fluid communication for the second fluid between the contact chambers of each of the frame assemblies. A portion of the first fluid is adapted to be introduced into each of the tubular membranes through separate first inlet means and is adapted to be withdrawn therefrom through separate first outlet means. The second fluid is adapted to be introduced into at least one of the contact chambers through separate second inlet means and is adapted to be withdrawn from another of the contact chambers through separate second outlet means so that the second fluid is conducted substantially throughout the contact chambers in contact with the pluralities of tubular membranes to selectively separate the matter between the first and second fluids.
