AmberLite HPR8400 H

Summary

Product identification

Product Name: AmberLite™ HPR8400 H Ion Exchange Resin Product Type: Weak Acid Cation Exchange Resin Matrix: Macroporous Copolymer: Crosslinked acrylic Functional Group: Carboxylic acid Description: High-quality resin for industrial demineralization, softening, and dealkalization applications requiring high performance and cost-effective operation. Features high total capacity and larger particle size for excellent operating capacity with low pressure drop, reducing chemical regenerant and water usage.

Applications

• Demineralization, particularly for water with:
  • High oxidant level (among WAC resins)
  • Total hardness to alkalinity ratio > 0.8
• Industrial softening
• High-salinity softening (operated in the Na-form)
• Dealkalization
• Reverse osmosis pretreatment (protects membranes from hardness scaling, improves system recovery and reliability, potentially eliminates antiscalants or pH control chemicals)

System Designs

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