Abstract

The desalinization system (S) in the first present invention which converts seawater and wastewater to fresh water is provided with a heat exchanger (6) that exchanges heat between wastewater or treated wastewater and seawater. The desalinization system (S) in the second present invention which also converts seawater and wastewater to fresh water is provided with the following: a membrane separation activated sludge treatment device (1) that treats wastewater using a membrane separation activated sludge method; a first RO membrane (2) that removes salt from the output (s5a) of the membrane separation activated sludge treatment device (1) by transferring said salt to first concentrated water (s6) thereby producing industrial use water (s1); a UF membrane (3) that seawater passes through and that removes particulates from said seawater; a second RO membrane (5) to which treated water (s5b) that has passed through the UF membrane (3) is sent whereby salt is removed from said treated water (s5b) and transferred to second concentrated water (s7) thereby producing drinking water (s2); and a heat exchanger (6) that exchanges heat between the wastewater or treated wastewater (s5a s6 s1) and seawater.
