ion exchange based water softening is a proven way of reducing excessive hardness content in water and is a time-tested method used globally.  synthetic polystyrene material in the form of very small spherical-shaped beads called cationic resins are used in this method to facilitate the exchange process. 

in this water softening process, the salts that induce hardness in the water (ca / mg) are substituted by a soft salt (sodium-na) in a process termed as ion exchange.  the crosslink structure of the resins contains negatively charged ‘exchange sites’ that can hold the ions.

when the raw water containing hard salts is passed through a bed of cationic resins supersaturated with sodium, these resins act as an exchange point where calcium and magnesium ions in the feed water stick to the ‘exchange sites’ on the resin surface and the sodium ions are knocked off.  calcium and magnesium both being divalent easily displace the monovalent sodium ions and get attached to the resin.  feed water will continue to get softened until the resins get saturated with hard salts
