Abstract: A method and apparatus for generating a sterilizing solution, wherein there is generated a supply of softened water by passing water through an ion-exchange water softener, and a supply of saturated salt solution by mixing a first part of the supply of softened water with a supply of salt. A second part of the supply of softened water is mixed together with a first part of the supply of saturated salt solution in a predetermined ratio and passed through at an electrolytic cell having a working chamber and an auxiliary chamber separated by a porous membrane, one of the chambers including an anode and the other including a cathode, the output from the working chamber being the sterilizing solution. The ion-exchange water softener is regenerated with a second part of the supply of saturated salt solution.

Abstract: There is disclosed a method and apparatus for generating a sterilizing solution through the electrolytic treatment of an aqueous salt solution. An aqueous salt solution is passed, under pressure, into the working chamber of an electrolytic cell, which cell is divided into a working chamber and an auxiliary chamber by a permeable membrane. The solution is filtered through the membrane, and collected from an output of the auxiliary chamber. Gases, such as chlorine, liberated in the working chamber during electrolysis, are dissolved in a water supply, and this water supply is partially or fully mixed with the output of the auxiliary chamber so as to generate a sterilizing solution. The method and apparatus disclosed serves to generate a sterilizing solution with less expenditure of energy and raw materials than in the prior art.
