Drinking Water-grade Resin for Selective Nitrate Removal
DuPont AmberLite PWA5 Ion Exchange Resin is a strongly basic anion exchange resin developed for selective nitrate removal from drinking water. AmberLite PWA5 removes nitrate preferentially to sulfate and, therefore, can yield operating capacity higher than conventional resins. These characteristics make AmberLite PWA5 the perfect choice for a simple, regenerable, nitrate removal process for municipal water
treatment.
