We Ion Water Machineries manufacturer and supplier of water softening plant for domestic and industrial water treatment purpose. 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 thy 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 minerals ions and remove them from the water. When the bead seizes the mineral ion, the sodium ion is released. The columns of resin of resin strips all the hardness out of the water as it passes through the mineral tank and softened water flows out into your home and industries.
