Claim:
1. A water treatment system for a residential or commercial application comprising: an electrochemical water treatment device comprising a series of alternating cation and anion exchange membranes positioned between a cathode and an anode; a concentrate stream in fluid communication with at least one cation exchange membrane and at least one anion exchange membrane of the series of alternating cation and anion exchange membranes, the concentrate stream having an LSI that is less than about 1.0; and a dilution stream in fluid communication with at least one cation exchange membrane and at least one anion exchange membrane of the series of alternating cation and anion exchange membranes, wherein the cation and anion exchange membranes are 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, and the water treatment system is configured to operate such that it does not require a reverse polarity cycle.
