AmberLite HPR9100 Cl

Summary

Product identification

AmberLite™ HPR9100 Cl Ion Exchange Resin is a uniform particle size, macroporous, strong base anion (Type II) exchange resin designed for industrial demineralization applications.

Description

This resin is optimized for a balance of operating performance and simple, cost-effective operation. Its macroporous structure offers resistance to organic fouling and physical stress, potentially leading to a longer operational lifespan compared to gel Type II resins. Type II resins can provide greater operating capacity than Type I resins due to more complete regeneration.

AmberLite™ HPR9100 Cl is best suited for treating water where silica and carbon dioxide do not exceed 30% of the total anions and where service and caustic regeneration temperatures do not consistently exceed 35°C (95°F). For applications requiring low effluent silica or higher operating temperatures, Type I strong base anion resins like AmberLite™ HPR9200 Cl or AmberLite™ HPR9000 OH or SO₄ are recommended.

Applications

• Demineralization, particularly with:
  • High organic fouling potential

Hydraulic Characteristics

Figures are provided in the original document for estimated bed expansion during backwash and estimated pressure drop during the service cycle as a function of flowrate and temperature.

• Backwash Expansion: Figure 1 in the document shows estimated bed expansion.
• Pressure Drop: Figure 2 in the document shows estimated pressure drop for clean water at the start of the service run.

Note: Hydraulic characteristic figures are valid for temperatures between 10 – 60°C (50 – 140°F).
