A carbonic water production apparatus equipped with a carbonic acid gas dissolving apparatus 3 and a circulation pump 1 wherein water in a bath 11 is circulated by the circulation pump 1, and a carbonic acid gas is fed into the carbonic acid gas dissolving apparatus 3 to dissolve the carbonic acid gas in the water, and wherein the circulation pump 1 is a positive-displacement metering pump having a self-priming ability; a carbonic water production method using this apparatus; a carbonic water production method comprising an early step for producing a carbonic water and a concentration maintaining step for the carbonic water; a carbonic water production apparatus equipped with a control for controlling the feeding pressure of carbonic water gas so that give an intended concentration of carbonic acid gas; a carbonic water production apparatus which automatically discharges out a drain; and a carbonic water production apparatus combined with a portable foot bath.
A carbonic water production method which comprises feeding a carbonic acid gas into a carbonic acid gas dissolving apparatus while flowing a raw water to dissolve the carbonic acid gas in the raw water, and which is characterized by comprising a step of previously recording a correlation data of the flow rate of raw water with the feeding pressure of carbonic acid gas and the concentration of carbonic acid gas in resulted carbonic water, and a step of detecting the flow rate of raw water and controlling the feeding pressure of carbonic acid gas according to the correlation data so that the resulted carbonic water has an intended concentration of carbonic acid gas at the time of producing the carbonic water.
A carbonic water production apparatus which feeds a carbonic acid gas into a carbonic acid gas dissolving apparatus thereof while flowing a raw water therein to dissolve the carbonic acid gas in the raw water, and which is characterized by being previously recorded a correlation data of the flow rate of raw water with the feeding pressure of carbonic acid gas and the concentration of carbonic acid gas in resulted carbonic water, and is equipped with a means for detecting the flow rate of raw water and controlling the feeding pressure of carbonic acid gas according to the correlation data so that the resulted carbonic water has an intended concentration of carbonic acid gas at the time of producing the carbonic water.
