Ion exchange is the reversible interchange of ions between a solid (the ion exchange resin) and a liquid. Since they act as “chemical sponges”, ion exchange resins are ideally suited for effective removal of contaminants from water and other liquids. This technology offers a number of advantages in industrial water demineralization and softening, wastewater recycling and other water treatment processes-including high water recovery, low volume of waste and operational flexibility. Ion exchange resins are also used in a variety of specialized applications such as chemical processing, pharmaceuticals, mining, and food and beverage processing. AMBERLITE™ and AMBERJET™ resins (formerly brand of Rohm & Haas) are among the world’s leading brands of ion exchange resin technology.
