Abstract: Methods and systems for treating brackish desalination brine for the recovery of fresh water are disclosed. The method includes treating a source of brackish desalination brine with an ultraviolet-driven persulfate photolysis oxidation pre-treatment; treating the source of brackish desalination brine treated with the ultraviolet-driven persulfate photolysis oxidation pre-treatment to a chemical demineralization process; treating the source of brackish desalination brine treated with the ultraviolet-driven persulfate photolysis oxidation pre-treatment and with the chemical demineralization process to a microfiltration process; and treating the source of brackish desalination brine treated to the ultraviolet-driven persulfate photolysis oxidation pre-treatment, the chemical demineralization process, and the microfiltration process to a reverse osmosis treatment.
