Abstract (en)

[origin: WO9842625A1] There is disclosed a method and apparatus for the electrolytic treatment of water and aqueous salt solutions. A relatively concentrated aqueous salt solution (A) is passed, under pressure, into the working chamber (1) of an electrolytic cell, which cell is divided into a working chamber (1) and an auxiliary chamber (4) by a permeable membrane (3). A first proportion of the solution (A) passes through the membrane (3) into the auxiliary chamber (4), while a second proportion of the solution (A) is passed out of the working chamber (1) and directly recirculated thereto by way of a pipe (12). Gases, such as chlorine, liberated in the working chamber during electrolysis, are dissolved in a water supply (C) so as to generate a supply of water with oxidising properties.
