PURPOSE:To accurately alter the concentration of carbon dioxide in carbonated water within a short time without altering the partial pressure of carbon dioxide in a carbonator in the subject apparatus. CONSTITUTION:In an apparatus for preparing carbonated water from dehydrated and cooled treated water by a carbonator, the bypass pipe 21 branched from a connection pipe 19 sending treated water to the carbonator 16 is connected to the liquid feed pipe 20 from the carbonator 16 and flow rate control valves 24, 25 are provided to the liquid feed pipe 20 and the bypass pipe 21 to be controlled by the signal of the carbonated water concn. detector 23 provided to the liquid feed pipe on the downstream side of the confluent place of the bypass pipe 21. |
