To provide a method for manufacturing a carbonate spring which is capable of easily and inexpensively manufacturing a carbonate spring containing carbon dioxide with high concentration, and to provide a manufacturing apparatus thereof.
The manufacturing apparatus of the carbonate spring is provided with a means 1 for manufacturing an alkaline aqueous solution containing bicarbonate ion to manufacture the alkaline aqueous solution containing the bicarbonate ion and an acid transferring means 2 for acidifying the alkaline aqueous solution containing the produced carbonate ion. The means 1 for manufacturing the alkaline aqueous solution containing the bicarbonate ion is provided with a means 3 for manufacturing alkaline water by electrolyzing water, and a means 4 containing the bicarbonate ion to make the alkaline water contain the bicarbonate ion by blowing carbon dioxide to the produced alkaline water. The carbonate spring containing carbon dioxide with high concentration can be easily and inexpensively manufactured by acidifying the alkaline aqueous solution because carbon dioxide can be dissolved in the acid aqueous solution.
