  • Membrane module assembly
    Patent number: 5681438
    Abstract: A membrane module in which non-porous membranes are bonded to spacer elements, which elements are in turn bonded to each other to create a membrane support zone as a result of contact with the surface of the membrane opposite the surface to which the membrane is bonded. The membrane is restrained from peeling from the membrane bond by the support zone under opposing pressure as may be caused by fluid flowing past the membrane. The preferred use of such a membrane module is for continuous electrodeionization processes.

  • Manifold apparatus for tangential flow filtration apparatus
    Patent number: 5599447
    Abstract: A manifold segment is provided for tangential flow filtration apparatus. The manifold segment includes a fluid feed conduit, a retentate conduit, a filtrate inlet and a filtrate outlet. An adaptor manifold is provided which directs filtrate from the manifold segment into a tangential flow filtration module and directs filtrate from the module into the manifold segment. Filtrate introduced into the tangential flow filtrate module reduces pressure drop across a filter layer in the module.
