Original Abstract Submitted
Methods for forming a treated water may comprise: obtaining a produced water comprising at least a divalent metal ion from a subterranean formation; introducing an accelerator into the produced water; wherein the accelerator comprises a zwitterionic compound; introducing a carbon dioxide gas into the produced water; allowing the carbon dioxide gas to react with the divalent metal ion in the presence of the accelerator to form a carbonate salt of the divalent metal ion; and removing the carbonate salt of the divalent metal ion from the produced water to form a treated water having a lower divalent metal ion concentration than the produced water.
