Why can ion exchange softeners save salt consumption?
By removing dissolved salts from the water as precipitated carbonates, they are no longer present as ions in solution. This means that the volume of water which a given size of softener will treat between regenerations can be extended. Savings on salt usage would mean that a large hotel can save ,000’s per year and also reduce contamination of ground water as well as water consumption. In some areas of U.S.A., salt based water softeners are already being banned due to the salt fouling potable water reserves.
