Electrochemical treatment of an aqueous salt solution

Abstract

A device () for producing a biocidal solution has a sealed and replaceable reservoir () with a low volume capacity which contains pre-prepared aqueous salt solution () with a pre-determined concentration, an electrolytic cell () for electrochemically treating the salt solution (), a pump () for delivering a flow of accurately measured volumes of the salt solution () to the electrolytic cell (), a restrictor valve () for controlling further the flow rate of the salt solution () to a cathode chamber () of the electrolytic cell (), an electrical circuit () for connecting the pump () and the electrolytic cell () to a mains supply source () and including a power pack () for providing a substantially constant direct current of (7) to (12) amps to the electrolytic cell () and an operator-controlled switch () for completing the electrical circuit () when the switch () is operated to produce a biocidal solution () having a predetermined level of available free chlorine and pH.
