Highly selective for monovalent anions, especially chloride and nitrate, enabling precise removal in complex matrices.
Optimized macroporous polystyrene-divinylbenzene matrix ensures excellent chemical and osmotic stability across wide pH and temperature ranges.
Low pressure drop and high hydraulic throughput due to uniform spherical bead morphology (0.4–1.2 mm) and narrow particle size distribution.
USP Class VI and FDA-compliant for use in pharmaceutical water purification and food-grade process streams.
Regenerable with standard sodium chloride solutions, supporting sustainable operation and reduced waste generation.
Pharmaceutical-grade purified water (PW) and water for injection (WFI) polishing in GMP-compliant facilities.
Nitrate and sulfate removal from municipal and industrial drinking water supplies.
Pre-treatment for reverse osmosis (RO) systems to protect membranes from anionic fouling.
Electronics industry ultrapure water (UPW) final polishing for semiconductor manufacturing.
Food and beverage process water dechlorination and residual anion control.
