  • 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.

  • Patent number: 10583398
    Abstract: According to the present invention, since a pretreatment mechanism can be operated while inhibiting the pretreated water from fluctuating in pressure, a fresh-water production apparatus is obtained in which the desalting mechanism can be stably operated. Furthermore, the period of water supply or flushing in the step of washing the pretreatment mechanism can be shortened, and the load on the lines where washing is not being performed is hence reduced. Consequently, a fresh-water production apparatus is obtained in which the pretreatment mechanism can be operated while inhibiting the pretreatment membranes from being fouled.

  • Publication number: 20140131281
    Abstract: A membrane filtration method and membrane filtration device including a pre-treatment membrane module that filters raw water with a filtration membrane and obtains pre-treated water; a reverse osmosis membrane module that filters the pre-treated water obtained from the pre-treatment membrane module with a reverse osmosis membrane and obtains permeate and retentate; a communicating tube channel that directly joins the pre-treated water outlet of the pre-treatment membrane module and the pre-treated water inlet of the reverse osmosis membrane module; and a branch tube channel that branches from the communicating tube channel and diverts a portion of the pre-treated water flowing in the communicating tube channel from the communicating tube channel. The filtration membrane of the pre-treatment membrane module is backwashed using the pre-treated water that has been diverted by the branch tube channel.
