Water Softener is a water hardness removal process. Conventional application for household use depends on an ion-exchange resin in which those hardness ions, i.e. calcium and magnesium, are substituted by sodium ions that are electrostatically bounded.

Resins are also able to remove carbonate, bi-carbonate and sulfate ions which are absorbed and hydroxyl ions released from the resin. Both types of resin may be provided in a single water softener.

TOP RICH softener equipments are the application of activated carbon and ion-exchange resin column. These were designed to purify water as a drinkable quality. Activated Carbon removes odors, colors, turbidity, heavy metals, organic compounds  and chlorines. Moreover, resin removes total hardness together with calcium carbonates which cause nephrolithiasis and kidney disease.
