As an apparatus used for electrolysis, an existing apparatus can be used, but an apparatus (described later) which is particularly improved for producing the sterilized water of the present invention can also be used. The production may be either a batch type or a continuous type, but industrially a continuous type is preferable.
電極は、アノードについては、有害な金属イオンが溶出

It is also possible to use it as such, and even by such adjustment, if the residual chlorine concentration is in the range of 1.0 to 200 ppm, the bactericidal effect is maintained. Where the residual chlorine concentration and
As the alkaline water used for adjusting the pH, the NaOH-containing water obtained on the cathode side during the electrolysis of the saline solution is used, but of course, an aqueous NaOH solution may be added from outside the system.
