At present, softening generally refers to the removal of calcium and magnesium ions from water by sodium ion exchange resin.

The principle of softening water treatment is ion exchange. Calcium and magnesium ions, which form the degree of hard seawater desalination equipment, are replaced by sodium ions by ion exchange resins of water-using equipment in the electronics industry. The water produced is softened water.

Effect on water quality: Ca and Mg ions in raw water are replaced by Na ions.

The treated water, of course, contains salt, and the softening is displacement rather than removal. There was no significant change in salt content before and after treatment.

The content of sodium ion in treated water increased. Making general household water can reduce scaling.
