Reactivation Of Ion Exchange Resins For Water Treatment Application

Ion exchange resin or IX resin is a synthetic polymeric ion exchanger that has been extensively used in water purification process to remove soluble ionized contaminant in water such as hardness ions (E.g., Ca, Mg). In water purification process, SAC (H-form) and SBA (OH-form) IX resins are common...
