AmberLite IRA67

Summary

Product Identification

• Product Name: AmberLite™ IRA67 Ion Exchange Resin
• Product Type: Gaussian, Acrylic, Gel, Weak Base Anion Exchange Resin
• Manufacturer: DuPont™

Description

AmberLite™ IRA67 is a general-purpose demineralization resin designed for industrial water treatment. It is characterized by high capacity, good stability, and resistance to organic fouling. This weak base anion resin is suitable for co-flow regenerated systems and is effective in removing mineral acids, carbon dioxide, and organic contaminants, thereby reducing the load on strong base anion resins and protecting them from fouling. Its hydrophilic acrylic structure allows operation under continuous high organic loads when temperatures do not exceed 35°C (95°F).

Applications

• Demineralization, particularly for water with:
  • High organic fouling potential
  • High percentage of mineral acidity
  • Relatively high remaining carbon dioxide content
  • System layouts without a degasifier

System Designs

• Co-current
