Abstract: A carbonate spring producing system includes a gas-liquid separator which is connected on the downstream side of a carbonic acid gas dissolver which connects to a carbonic acid gas supply means and hot water supply. A liquid lead-out pipe is connected to the gas-liquid separator. Preferably an un-dissolved carbonic acid gas lead-out pipe is connected on the upstream sides of the gas-liquid separator and the carbonic acid gas dissolver. The un-dissolved carbonic acid gas lead-out pipe includes a control valve, a compressor, and a liquid level detection means. The control valve controls a flow rate of un-dissolved carbonic acid gas from the gas-liquid separator. An amount of un-dissolved carbonic acid gas in the gas-liquid separator is monitored, so that the un-dissolved carbonic acid gas in the hot water can be separated and removed by the gas-liquid separator. The separated and removed un-dissolved carbonic acid gas can be re-dissolved.

Abstract: Hot water is pumped by a suction pump and introduced into a carbon dioxide (CO2) gas dissolver through solution flow rate adjusting means and then poured into a bath. The CO2 is introduced into the CO2 gas dissolver through gas flow rate adjusting means, and the quantity of bubbles in an artificial carbonated spring in a take-out pipe is measured. The solution and gas flow rate adjusting means are controlled via a control device using a relationship expression between a preliminarily set quantity of bubbles and carbon dioxide concentration to obtain a desired concentration of carbon dioxide gas in the carbonated spring. Since the carbon dioxide gas flow control means is provided between the carbon dioxide gas dissolver and a carbon dioxide gas supply source, a high concentration carbonated spring can always be manufactured, even if the pressure of supplied carbon dioxide gas changes or membrane permeation changes.

Abstract: This invention concerns an apparatus and a method for producing carbonated water capable of obtaining high concentration carbonated water effectively. Carbon dioxide gas is passed through a first carbon dioxide gas dissolver composed of a membrane module to be dissolved in water and the carbonated water passing through the first carbon dioxide gas dissolver is passed through a static mixer, which is a second carbon dioxide gas dissolver. Consequently, a high concentration carbonated water can be obtained remarkably, effectively and easily with a simpler structure than conventionally.
