Disclosed is an improved method for the remineralization of process water in a desalination system. The method sequesters carbon dioxide gas (CO 2 ) from seawater or concentrate (brine) of desalination process via a gas transfer membrane. The sequestered carbon dioxide gas (CO 2 ) is thereafter used in the production of soluble calcium bicarbonate (Ca(HCO 3 ) 2 ). The calcium bicarbonate (Ca(HCO 3 ) 2 ) adds hardness and alkalinity to the resulting process water. |
