We are Ion Water Machineries AN 9001:2015 certified water treatment company engaged in manufacturing and supplying of water softening plant on sodium based cation exchanger. 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 resin beads usually made from polystyrene are charged with a sodium ion, the resin beads are anion, meaning they have a negative charge, 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 s 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. In case raw water iron contains is more than 0.3ppm as Fe, an iron removal filter must be installed before a softener. This is to avoid iron fouling of Ion Exchange resin in softener. Capacity 50 to 50000 gallon per hour and above.
