Overview

Efficient acid uptake with lower regenerant demand.

Low-regenerant anion exchange for removing strong mineral acids and reducing load before polishing stages.

  • Macroporous
  • Strong mineral acid removal
  • Caustic regeneration

Selection guidance

Where this family fits best.

Best for

  • Strong mineral acid removal
  • Organic fouling resistance
  • Lead beds before SBA polishing

Review carefully for

  • Silica-critical high-purity trains needing SBA
  • Streams needing broad weak-acid anion removal

Applications

Relevant use cases for WBA.
