We Ion Water Machineries specialist on manufacturer and supplier of water softening plant in West Bengal since 1967. Water softener work through a process called Ion Exchange which eliminates Calcium and Magnesium from the raw water. When the hard water enters into the mineral tank, it flows through a bed of spherical resin beads. These plastic beads usually made from polystyrene, are charged with a sodium ion, the resin beads are anions, meaning they have a negative charges, the Calcium and Magnesium minerals have a positive charge, making them Cations, since opposite charge attract the negative charge of the minerals is attracted to the positive charge of the resin beads. As the hard water passes through the resin the beads grab a hold of the mineral ions and remove them from the water, when the bead seizes the mineral ion the sodium ion is released. The colums of resin strips all the hardness out of the water as it passes through the mineral tank and softened water flows out into your surrounding area. Capacity 50 to 50000 gallon per hour and above.
