The Water Softening Plants are designed to produce treated Water to suit for various applications. Treated Water is of consistency quality with low residual hardness throughout the service cycle. The high synthetic resin is used to exchange Sodium ion with hardness forming Calcium and Magnesium ions.Home water softeners, also called ion exchange units, are appliances that remove calcium, magnesium, and other minerals from drinking water. Resin beads inside the softener trap the calcium and magnesium and exchange them for sodium or potassium.A Water Softener is a filtration system that works to remove high concentrations of calcium and magnesium that cause hard water. When water flows through a Water Softener, the system filters out these hard water minerals and the softened water then leaves the water softening system to flow through plumbing.
