Abstract

PURPOSE:To permit a desired pH value to be obtained by dissolving a specific amt. of salt (NaCl) in an aq. solution of hydrochloric acid (HCl). CONSTITUTION:Since an aq. HCl solution and NaCl are intermixed in one liq. solution, by the neutral action of HCl, the pH of the resulting bactericidal solution can be lowered to a value of 3-7 with less power consumption. An additive chemical solution is prepared in such a mixing ratio that the NaCl concn. is 10-30% and the HCl concn. is 1/6-1/3 the NaCl concn. and the original water with this additive solution added thereto is electrolyzed, whereby the pH of the total amt. of the electrolytic solution resulting from a diaphragm-free electrolysis retained at value of 3-7 and whereby the pH of the total mixture of the electrolytic solution on the anode side and that on the cathode side resulting from the diaphragm electrolysis conducted with the electrodes separated by the diaphragm is retained at a value of 3-7. In this way a desired pH value can be obtained.

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an additive chemical solution suitable for producing hypochlorous acid-containing sterilized water by electrolysis.

However, in the pH range of 3 to 7, it is maintained in the form of HCl0,
It is known that the bactericidal power increases dramatically (see Figure 2). Therefore, hypochlorous acid water with a pH of 3 to 7 has a residual chlorine concentration of pH 8 even if the residual chlorine concentration is as low as 30 to 60 ppm. The same sterilizing effect as sterilizing water of about 200 ppm can be obtained. Therefore, as a method for obtaining this type of sterilized water, a sodium chloride aqueous solution is electrolyzed to obtain hypochlorous acid water having a pH of 3 to 7 on the anode chamber side.

In addition, in the raw water of sodium chloride aqueous solution, calcium is mainly present in the form of calcium bicarbonate, Ca (HCO3) y.
Since Ca is dissolved in the aqueous solution, Ca precipitates during the electrolytic treatment of the aqueous sodium chloride solution, and this adheres to the cathode, causing problems such as an increase in the electrolytic voltage and a difficulty in the flow of electrolytic current. Due to similar reasons, water flow resistance increases and the amount of water supplied decreases, making it impossible to operate continuously, especially in electrolyzers that electrolyze water by continuously passing water through it.

However, in the method of the above-mentioned patent application, aqueous solutions of sodium chloride (NaCl) and hydrochloric acid (HCI) at predetermined concentrations were separately added to raw water.
