Weak Base Anion (WBA) Macroporous Products

Macroporous weak base anion ion exchange resins from Purolite have excellent mechanical, osmotic, and chemical stability, combined with the capability of very fast rates of ion exchange, making them particularly suitable for the removal of high molecular weight organic materials from aqeous solutions. The particle size range can also be specially designed to suit continuous process operation, or for operation at higher than average flow rates.

Typical applications for WBA macroporous resins:

  • Acid removal
  • Boron removal
  • Citric acid production
  • Decolorization - sugar solutions
  • Demineralization - high TDS waters
  • Demineralization - sugar solutions
  • Enzyme immobilization
  • Mineral acid removal
  • Organic matter removal
  • Sweetener deashing
