Ion Exchange Resins Supplier - Water Treatment

Ion exchange resins are synthetic polymers used in water treatment to remove undesirable ions and replace them with desirable ones. They are commonly employed for softening hard water by exchanging calcium and magnesium ions with sodium ions. These resins are also used for demineralization, removing contaminants like heavy metals and nitrates from water.
