Abstract
A method of simultaneously completely deoxygenating and partially carbonating a supply of water is disclosed. The method includes the steps of receiving and metering a flow of water, injecting at a positive pressure a first flow of carbon dioxide gas into the metered, flowing water, introducing the flow of metered, carbonated water into a vessel, maintaining the pressure within the vessel at less than one atmosphere, and drawing off the deoxygenated, carbonated flow of water. Equipment for performing this process is also disclosed. The equipment includes a metering device, deoxygenating column vessels, and devices for injecting the carbon dioxide gas into the water as the water flows from the metering device to the deoxygenating vessels.
