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.
