Document Type and Number:
Japanese Patent JP2007007502
Kind Code:
A
Abstract:
To provide a manufacturing method of low sodium chloride electrolytic water including hypochlorous acid and a manufacturing device thereof, capable of lowering the concentration of sodium chloride although using an electrolytic method of sodium chloride capable of suppressing the included bromic acid to the regulation value or less.
In the manufacturing method of low sodium chloride electrolytic water, a sodium chloride aqueous solution is electrolyzed, pH of produced electrolytic water is adjusted to be acidic, and the aqueous electrolyte whose pH is adjusted is electrically dialyzed to separate and remove sodium ions and chloride ions in the electrolytic water.
