METHOD AND APPARATUS FOR PRODUCING A STERILISING SOLUTION

摘要

A method and apparatus for generating a sterilising solution, wherein there is generated a supply of softened water by passing water through an ion-exchange water softener (4, 5), 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 (32) 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 sterilising solution. The ion-exchange water softener (4, 5) is regenerated with a second part of the supply of saturated salt solution.
