WATER ELECTROLYSIS TREATMENT DEVICE

WIPO Patent Application WO/2012/050131

A1

Provided is a water electrolysis treatment device that is not readily contaminated or damaged, is capable of stably producing high-purity water, is easy to handle, can be readily dismantled or exchanged, and can be inexpensively manufactured and maintained. The water electrolysis treatment device comprises: a treatment tank; an anion tube having a cylindrical anion-permeable membrane inside the treatment tank; a cation tube having a cylindrical cation-permeable membrane inside the treatment tank; a positive electrode provided in the axial direction of the cylindrical shape of the anion-permeable membrane on the inside of the cylindrical shape; and a negative electrode provided in the axial direction of the cylindrical shape of the cation-permeable membrane on the inside of the cylindrical shape. A configuration is adopted in which water to be treated, which is stored in the treatment tank, can flow in the axial direction of the cylindrical shape of the anion and cation tubes inside the treatment tank, producing ion-concentrated water with concentrated ions in the anion and cation tubes, and purified water in the tank to be treated.
