  • Membrane separation system and operation method for membrane separation system
    Patent number: 11369924
    Abstract: The present invention relates to a membrane separation system including a plurality of separation membrane elements connected to one another, each of the separation membrane elements including a plurality of separation membrane pairs, each separation membrane pair including separation membranes each having a feed-side surface and a permeate-side surface and disposed such that the feed-side surfaces face each other, in which the plurality of separation membrane elements include a first separation membrane element and a second separation membrane element, and at least one first separation membrane element serves as a stage preceding the second separation membrane element.
    Type: Grant
    Filed: December 25, 2018
    Date of Patent: June 28, 2022
    Assignee: Toray Industries, Inc.
    Inventors: Akshay Garg, Yoshiki Okamoto, Shinichiro Yoshidomi, Shigehisa Hanada, Norihiro Takeuchi
  • Separation membrane element
    Patent number: 11065580
    Abstract: According to the present invention, even when a high recovery ratio operation is performed, the influence of concentration of ingredients to be separated in the feed fluid can be reduced, the concentration polarization can be prevented by increasing the turbulence effect on the membrane surface, and the fluid permeation performance and the separation performance of the separation membrane element can be maintained.

  • SEPARATION MEMBRANE ELEMENT
    Publication number: 20190160435
    Abstract: The present invention relates to a separation membrane element for use in separation of ingredients contained in fluids such as liquid and gas. An object of the present invention is to provide a separation membrane element which, even when used in a high-recovery ratio operation, has high fresh-water production performance and high removal performance and is less apt to suffer scaling.
