Water Softening Chemical

Softening is the ion exchange process, it is done through resin, the most common and probably the easiest method of removing hardness (that is calcium and magnesium)from water and suitable for utility purpose. As the name implies ion exchange is a process which undesirable ions are exchanged for more desirable ions.The softening process consists of passing raw water containing hardness through a bed of cation resin in sodium form.The hardness ions Ca & Mg are taken up by resin and in exchange,the sodium ions are relinquished from the resin.This is called the service cycle, where the hard water is being softened.
