Highly selective for monovalent anions (e.g., chloride, nitrate) in the presence of sulfate and carbonate.
Optimized macroporous matrix ensures excellent kinetic performance and resistance to fouling in complex feedwaters.
Superior chemical and thermal stability, suitable for continuous operation across wide pH (0–14) and temperature ranges (up to 60 °C).
Low operating pressure drop and high bed integrity, enabling efficient column design and long service cycles.
Regenerable with standard NaCl brine, minimizing operational cost and waste stream burden.
Removal of nitrate from drinking water and municipal potable water supplies.
Chloride reduction in pharmaceutical process water and ultrapure water (UPW) pretreatment loops.
Selective anion polishing in food & beverage production, especially for low-sulfate beverage water.
Industrial wastewater treatment targeting regulated anions prior to discharge or reuse.
Pre-treatment for reverse osmosis (RO) systems to protect membranes from competitive anion scaling.
