  • Computer-readable recording medium on which clogging location specification program for separation membrane module is recorded, water production system, and water production method
    Patent number: 11141701
    Abstract: The present invention relates to a computer-readable recording medium having recorded thereon a clogging location determination program for a separation membrane module, in which, in order to determine a clogging location of a separation membrane module in a fresh water generation system for obtaining treated water by filtrating water to be treated by a separation membrane module having a separation membrane, a computer is caused to function as a clogging location determination means for determining a clogging location of the separation membrane module from a resistance in a lower part of the separation membrane module, a filtration resistance of a hollow-fiber membrane, and a resistance in an upper part of the separation membrane module.
    Type: Grant

  • METHOD FOR OPERATING CLARIFYING-FILM MODULE
    Publication number: 20170043298
    Abstract: In a method for operating a clarification membrane module the invention, either following steps is conducted after the position of the closed ends in the clarification membrane module is made above the position of the open ends therein: (a) closed-end high-position cleaning step A in which the outer side of the clarification membranes within the clarification membrane module is filled with liquid and air scrubbing is then performed by supplying a gas; (b) closed-end high-position cleaning step B in which air scrubbing is conducted by supplying a gas, while supplying liquid to the outer side of the clarification membranes within the clarification membrane module.
