We Ion Water Machineries most trusted name in manufacturer and supplier of Water Softening Plant for domestic and industrial uses since 1967. Water softener work through a process called ion-exchange which eliminates Calcium and Magnesium from the 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 bead 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 colons of resin strips all the hardness out of the water as it passes through the mineral tank and softened water flows out into your use purpose. Capacity 50 to 50000 gallon per hour and above.
