Highly selective for nitrate (NO₃⁻) and perchlorate (ClO₄⁻) removal from drinking water and process streams.
Strong-base, Type I quaternary ammonium functional group provides excellent chemical stability in oxidizing environments.
Optimized bead uniformity and mechanical strength for low pressure drop and extended service life in fixed-bed systems.
Low soluble organic compound (SOC) leaching, meeting stringent regulatory requirements for potable water applications.
Regenerable with standard sodium chloride (NaCl) brine, enabling cost-effective cyclic operation.
Drinking water treatment for selective removal of nitrate and perchlorate contaminants.
Groundwater remediation in municipal and industrial settings affected by agricultural runoff or aerospace industry discharges.
Pretreatment for ultrapure water systems requiring low anionic impurity levels prior to polishing stages.
Wastewater polishing in semiconductor and pharmaceutical manufacturing facilities.
Recycling rinse water in metal finishing operations where chloride and sulfate control is critical.
