Process for releasing carbonized drinking water via a tap comprises enriching the tap water with carbon dioxide according to requirement in a carbonizing device. The enrichment is controlled in the tap water stream from the carbonization device to the tap outlet by the pressure drop that occurs when the tap is opened and the pressure build up that occurs when the tap is closed. An Independent claim is also included for an apparatus for releasing carbonized drinking water via a tap comprising a feed line connected to a pressure switch and/or regulator via a pressure line. The regulator is connected to a carbon dioxide source on one side and the carbonization device on the other side. Preferred Features: The pressure in the tap water stream from the carbonization device to the tap outlet is further fed to a pressure switch via a pressure line, in which the regulator controls the supply of carbon dioxide to the carbonization device. The carbonization device is a static mixer filled with balls and containing a pipe having a diameter of 20-50, preferably 25-35 mm and a total effective length of 0.2-1.5, preferably 0.8-1.2 m. The balls have a diameter of 1-10, preferably 2-5 mm. |
