Patent ID: 8448925

Claim:
A method for carbonation of deionized water comprising: supplying deionized water to a contactor; supplying carbon dioxide gas to the contactor; measuring, with at least one sensor, flow rate of the deionized water and temperature of the deionized water, wherein the at least one sensor is positioned at an inlet of the contactor or an outlet of the contactor; determining an amount of carbon dioxide gas to supply to the contactor such that a specific conductivity of carbonated deionized water is generated by the contactor in communication with the at least one sensor and the supply of carbon dioxide gas, wherein the determination is based on the measured flow rate and temperature; supplying the determined amount of carbon dioxide to the contactor via one or more flow restrictors and one or more valves that are in fluid communication with the supply of carbon dioxide gas and the contactor; and flowing the carbonated deionized water of a specific conductivity from the contactor.
