    摘要： The disclosed techniques involve electrical separation systems that allow recovery of species from feedstreams, typically aqueous solutions. The disclosed techniques can also provide electrical separation systems having reduced tendency to form scale especially when water is being purified to reduce the concentration of hardness-causing species.

    摘要： Systems and methods for process stream treatment. The treatment system may generally include an oxidation unit coupled to a downstream demineralization unit. The oxidation unit may oxidize organic and reduced sulfur contaminants in the process stream to facilitate downstream treatment. The demineralization unit may convert a product of the oxidation unit to generate a mineral stream. In some examples, the process stream may be a spent caustic stream from an industrial operation, such as an ethylene production facility or a petroleum refinery. A fresh caustic stream, such as a sodium hydroxide stream, may be isolated in the demineralization step and returned to the industrial operation for use.
