  • Method for desalinating sea water
    Patent number: 8070953
    Abstract: An object is to provide a fresh water generating method that is capable of efficiently producing purified water, such as fresh water, from unpurified water, such as sea water. Provided is a fresh water generating method for generating fresh water by way of reverse osmosis membrane filtration, which includes mixing sea water with low salt concentration water having a salt concentration lower than sea water to produce mixed water, and subjecting the mixed water prepared by the mixing to reverse osmosis membrane filtration, thereby generating fresh water.
    Type: Grant
    Filed: November 26, 2009
    Date of Patent: December 6, 2011
    Assignee: Kobelco Eco-Solutions Co., Ltd.
    Inventors: Yutaka Ito, Katsuhide Motojima, Kazuya Uematsu, Masanobu Noshita, Kazutaka Takata, Mitsushige Shimada, Megumi Manabe
