DOWEX™ Ion Exchange Resins

What is ion exchange?
Ion exchange is the reversible interchange of ions between a solid — the ion exchange resin — and a liquid. Ion exchange resins act as "chemical sponges" for effective removal of contaminants from liquids, such as water. In addition to water treatment applications, ion exchange resins can be used in many different specialized applications such as pharmaceuticals, fine chemicals, chemical processing, mining, catalysts, sweeteners processing, beverage and dairy processing, nuclear applications, bio-fuels and other demanding processes.
