AmberLite IRA900 Cl

Summary

Product identification

• Product Name: AmberLite™ IRA900 Cl Ion Exchange Resin
• Product Type: Gaussian, Macroporous, Strong Base Anion Exchange Resin
• Manufacturer: DuPont™

Description

AmberLite™ IRA900 Cl is a general-purpose demineralization resin designed for reliable performance in industrial water treatment. Its macroporous structure offers good resistance to organic fouling and physical stresses, potentially leading to a longer operational life compared to gel Type I resins, especially in co-flow regenerated systems.

Applications

• Demineralization, particularly for water with:
  • High organic fouling potential
  • High percentage of silica
• Treatment goals:
  • Removal of strong and weak acids
  • Achieving low silica leakage
• Organic scavenging
