Abstract

A system for removing minerals from a brine using electrodialysis. One system includes a gypsum removal system configured to receive a feed stream having a first amount of gypsum, to extract at least a portion of the gypsum from the feed stream, and to produce a first output having a second amount of the gypsum less than the first amount of the gypsum. The system also includes an electrodialysis (ED) system fluidly coupled to the gypsum removal system and configured to receive the first output from the gypsum removal system, to produce a second output having a substantially sulfate hardness free sodium sulfate solution, to produce a third output having a sodium chloride solution, and to produce a fourth output having a mineral solution.
