Macroporous structure ensures high mechanical strength and excellent resistance to osmotic shock during repeated regeneration cycles.
Weak base functional groups (tertiary amine) provide superior selectivity for strong acid anions (e.g., Cl⁻, SO₄²⁻) with efficient regeneration using mild alkali solutions.
Low water content and high porosity enable rapid mass transfer and enhanced kinetics in dynamic column operations.
Chemically stable in acidic environments (pH 0–14), making it suitable for pretreatment of highly acidic process streams.
Low pressure drop characteristics support high-flow-rate applications without channeling or bed compaction.
Decolorization and dechlorination of sugar syrups and sweeteners in the food & beverage industry.
Removal of nitrate and sulfate from industrial wastewater prior to discharge or reuse.
Pretreatment of feedwater for mixed-bed demineralizers in power plant boiler make-up systems.
Recovery of valuable acids (e.g., HCl, H₂SO₄) from metal finishing rinse waters.
Polishing step in pharmaceutical water purification systems to reduce total organic carbon (TOC) and ionic impurities.
