1. An oxidant generator comprising:

  • a shell for containing a saline solution;

    a tubular member extending generally vertically within said shell and having a side wall dividing the shell into a first chamber within the tubular member and a second chamber at the outside of said tubular member;

    an anode in one of said chambers and a cathode in the other chamber to be energized by a power source for production of oxidant gases at the anode and sodium hydroxide at the cathode;

    said side wall of the tubular member having a portion which curves as it advances horizontally about said first chamber and which contains at least one aperture curving with the wall and through which said chambers are in communication with one another;

    an ion permeable membrane secured to said wall and bridging across said aperture and which curves essentially in correspondence with the wall and aperture and is adapted to pass sodium ions from said anode chamber to said cathode chamber while resisting movement of sodium hydroxide from the cathode chamber to the anode chamber; and

    an adhesive securing the periphery of said membrane to said curving portion of said side wall about said aperture.
