    • Water Purification Technologies Ion exchange

      The ion exchange filtration is one of the most common water filtration methods. Ion exchange process percolates water through bead like spherical resin materials (ion exchange resins). Ions in the water are exchanged for other ions fixed to the beads. The two most common ion exchange methods are softening and deionization.
