(57) [Summary] (Modified) [Purpose] When sterilizing water to be treated, such as drinking water, by electrochemically sterilizing it, increase the sterilization efficiency or use a smaller amount of sterilizing agent Achieve sterilization efficiency, or prevent scale from adhering to pipes and prevent corrosion at the same time as sterilization. [Structure] Water to be treated in which at least one agent of scale adhesion preventing agent, anticorrosive agent and sterilizing agent is previously dissolved is supplied to an electrolytic cell, particularly an electrolytic cell containing a carbon electrode, and the water to be treated is supplied to the electrode. The sterilization efficiency is increased or the amount of the sterilizing agent to be used is greatly reduced by sterilizing the sterilizing agent by contacting it with the sterilizing agent and protecting the pipe with the scale adhesion preventing agent or the anticorrosive agent. |
