  • Patent number: 4261829
    Abstract: 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.

  • Patent number: 4250141
    Abstract: A column for removing poisons and/or other undesired substances from a liquid mixture. The column has a mixture of inactive filler particles and active granules positioned therein, with said filler particles being substantially larger than said active granules, (which are selected from adsorbing material and ion-exchanging material). The filler particles are in fixed contact relationship with each other and the active granules completely fill the spaces between the filler particles.

  • Patent number: 4231879
    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.

  • Patent number: 4225439
    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.
