Abstract
Systems and methods for treating water are provided. The systems and methods may utilize an electrochemical water treatment device comprising ion exchange membranes. In certain systems and methods, a concentrate stream and a dilution stream may be in fluid communication with ion exchange membranes. The ion exchange membranes may be configured to provide a ratio of a pH of the concentrate stream and a pH of the dilution stream to be less than about 1.0. In some instances, the LSI of the concentrate stream may be less than or about 1.0. In certain instances, the electrochemical water treatment device does not require a reverse polarity cycle.
