  • System and method for using carbon dioxide sequestered from seawater in the remineralization of process water
    Patent number: 7771599
    Abstract: Disclosed is an improved method for the remineralization of process water in a desalination system. The method sequesters carbon dioxide gas (CO2) from seawater or concentrate (brine) of desalination process via a gas transfer membrane. The sequestered carbon dioxide gas (CO2) is thereafter used in the production of soluble calcium bicarbonate (Ca(HCO3)2). The calcium bicarbonate (Ca(HCO3)2) adds hardness and alkalinity to the resulting process water.
