Abstract: The systems and methods disclosed herein process produced/flowback water, such as high total dissolved solids produced water, to generate high purity, high value products with little to no waste. The generated high purity, high value products include caustic soda, hydrochloric acid, and/or sodium hypochlorite. Further, the methods and systems disclosed herein generate high quality brine for electrolysis through the systematic removal of contaminants such as but not limited to suspended solids, iron, sulfides, barium, radium, strontium, calcium, magnesium, manganese, fluoride, heavy metals, organic carbon, recoverable hydrocarbons, silica, lithium, and/or nitrogen containing compounds. Further, some products generated by the systems and methods disclosed herein may be recovered and reutilized or sold for other uses, such as carbon dioxide, calcium oxide, chlorine, magnesium oxide, calcium carbonate, and/or barium sulfate.
