A method for removing hydrocarbons and scale forming compounds from tap water, contaminated aqueous solutions, seawater, and saline brines, such as produce water, comprising the addition of carbonate ions by CO 2 sparging, or divalent cations, so as precipitate calcium and magnesium carbonates by adjusting pH to about 10.2, thus permanently sequestering CO 2 from the atmosphere, and then removing such precipitates sequentially for either sale of disposal. |
