Cheetham Salt Limited produces the large, high purity salt crystals that are needed for water softening, Crown HG or Diamond Watersoftener Salt has long been recognised as the best available salt for water softeners. Naturally occurring salt water and solar evaporation are the basic ingredients of Crown HG or Diamond Watersoftener Salt, from the clear waters of the Southern Ocean feeding the salt fields of South Australia to the vast Pacific Ocean feeding the fields of Queensland.

An ion exchange water softener contains polymer or resin charged with sodium ions. As the hard water passes through the resin unit the calcium and magnesium ions in the water are displaced by the more soluble sodium ions thus negating the symptoms of hardness.

This exchange of soft ions for hard will eventually exhaust the sodium ions of the resin, however it is easily overcome by passing a concentrated salt solution over the resin. Called regeneration, the calcium and magnesium is displaced by sodium and the resin reactivated. Regeneration is usually automatic, the only input needed is to ensure salt is always available for the system to regenerate.
