Macroporous, Weak Base Anion Exchange Resin for Industrial Demineralization Applications

AmberLite HPR9700 Ion Exchange Resin is a high-quality resin for use in industrial demineralization applications when high performance and cost-effective operation is required. The chemical properties and particle size of the resin have been balanced to combine a good operating capacity with low pressure drop, while reducing chemical regenerant and water usage.

Weak base anion resins are well-suited for use with strong base anion resins to improve overall efficiency and throughput of a demineralization system. It effectively removes mineral acids and organics, reducing the ionic load on the strong base anion resin and
also protecting it from organic fouling. The weak base anion resin increases a system’s overall capacity to remove organics.

AmberLite HPR9700 has excellent physical and thermal stability. The macroporous structure allows for easy release of natural organic molecules providing excellent organic fouling resistance.
