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.

Apparatus for producing carbonated water and method for producing carbonated water using the same

A carbonic water production apparatus equipped with a carbonic acid gas dissolving apparatus and a circulation pump, wherein water in a bath is circulated by the circulation pump, and carbonic acid gas is fed into the carbonic acid gas dissolving apparatus to dissolve the carbonic acid gas in the water, and wherein the circulation pump is a positive-displacement metering pump having a self-priming ability; a carbonic water production method using this apparatus; a carbonic water production method including 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 device for controlling the feeding pressure of carbonic water gas so as to 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.
