  • Spiral wound membrane module and method of manufacture and use
    Patent number: 4792401
    Abstract: A spirally wound, high flux membrane module which comprises a feed inlet, a concentration outlet and two permeate outlets and one or more membrane leaves wrapped about a central permeate flow tube to define a permeate flow path in one or more of the membrane leaves and wherein the improvement comprises one or more of the membrane leaves containing two or more separate permeate flow compartments within the membrane leaf to provide for the separate permeate flow of the permeate within the separator compartments to the permeate outlet thereby reducing the area of the permeate back pressure and reducing membrane wrinkling and membrane failure particularly during the membrane cleaning cycles.
