Water Softening Salt

Water softening is the removal of calcium, magnesium and certain other metal cations in hard water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually achieved using or ion-exchange resins. Conventional water-softening appliances intended for household use depend on an ion-exchange resin in which “hardness ions” – mainly Ca2+ and Mg2+ – are exchanged for sodium (SALT) ions.[4] As described by NSF?ANSI Standard 44,[5] ion exchange devices reduce the hardness by replacing magnesium and calcium (Mg2+ and Ca2+) with sodium or potassium ions (Na+ and K+). We at Chicago Salt Company Inc. supply water softening salt year round to our customers. We provide transportation with dump trucks or pneumatic semi trucks that will blow the salt into your system.

Ion-exchange resins, in the form of beads, are a functional component of domestic water softening units.

If hard water is left un-treated lime scale built up will occur causing lower water volume in pipes.
