Ion Water Machineries manufacturer and seller of water softening plant since 1967 in all over Kolkata for domestic and industrial uses. 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 high polystyrene are changed 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 ahold of the mineral ions and remove them from the water. When the bead seizes the mineral ion the sodium ion is released. The coluns of resin strips all the hardness out of the water as it passes through the mineral tank and softened water flows out. Water Softening Plant capacity 50 to 50000 gallon per hour and above.
