Patent ID: 7374694

Claim:
A method for remineralizing raw water comprising: separating an input flow of raw water into a first flow of raw water and a second flow of raw water, wherein the first flow is less than 50% of said input flow; directing the first flow of raw water into a remineralization tank; bypassing the remineralization tank with the second flow of raw water; remineralizing the water in the remineralization tank by injecting carbon dioxide and an inorganic base into the remineralization tank and contacting the water in the tank with the carbon dioxide and the inorganic base for a selected residency time to obtain a saturation index between −0.5 and +0.1; directing remineralized water from the remineralization tank; mixing the remineralized water with the second flow of raw water; and injecting an inorganic base into the remineralized water after the first and second flows have been mixed.
