AmberLite HPR7000

Summary

Product identification

• Product Name: AmberLite™ HPR7000 Ion Exchange Resin
• Type: Weak Base Anion Exchange Resin
• Matrix: Gel
• Copolymer: Crosslinked acrylic
• Functional Group: Tertiary amine
• Physical Form: White, translucent, spherical beads
• Historical Reference: Previously sold as AmberLite™ IRA70RF Ion Exchange Resin.

Applications

• Industrial demineralization requiring high performance and cost-effective operation.
• Ideal for treating water with:
  • High organic fouling potential
  • High percentage of mineral acidity (FMA)
  • Relatively high remaining carbon dioxide content
  • System layouts without a degasifier
• Co-removal of mineral acids, carbon dioxide, and organics.
• Can be used with strong base anion resins to improve system efficiency and throughput.
• Offers increased system capacity for organic removal.
• Exceptional physical stability and organic fouling resistance.
• Suitable for continuous high load of natural organic compounds when temperatures do not consistently exceed 35°C (95°F).

System Designs

• Co-current
• Counter-current / Hold-down
• Packed beds
