It was necessary to use an chlorine injection device that supplies the above-mentioned sodium hypochlorite as a medicine and supplies it regularly, or an electrolytic device for supplying the salt solution to electrolyze the salt solution in the field.

In this case, a metering pump was used to meter the salt solution into the electrolytic cell or to inject the resulting sodium hypochlorite. In the case of using a metering pump, the diaphragm of the metering pump is aged for a long time or salt is precipitated in the metering pump when used discontinuously, resulting in abnormal operation of the pump. As a result, the generation and concentration changes of sodium hypochlorite occur, and the pump operation for supplying the generated sodium hypochlorite to the tap water pipe is not smooth, and thus, the electrolytic disinfectant water of the required effect cannot be generated.
