A device 10 for producing a biocidal solution has a sealed and replaceable reservoir 16 with a low volume capacity which contains pre-prepared aqueous salt solution 18 with a pre-determined concentration, an electrolytic cell 20 for electrochemically treating the salt solution 18, a pump 28 for delivering a flow of accurately measured volumes of the salt solution 18 to the electrolytic cell 20, a restrictor valve 36 for controlling further the flow rate of the salt solution 18 to a cathode chamber (24, figure 3) of the electrolytic cell 20, an electrical circuit 46 for connecting the pump 28 and the electrolytic cell 20 to a mains supply source 48 and including a power pack 50 for providing a substantially constant direct current of 7 to 12 amps to the electrolytic cell 20 and an operator-controlled switch (52, figure 4) for completing the electrical circuit 46 when the switch 52 is operated to produce a biocidal solution 12 having a predetermined level of available free chlorine and pH. |
