Highly selective for nitrate (NO₃⁻) removal, even in the presence of competing anions such as sulfate and chloride.
Functionalized with type I strong base quaternary ammonium groups for stable performance across a wide pH range (0–14).
Optimized bead structure ensures low pressure drop and excellent hydraulic stability during continuous operation.
Regenerable with common brine solutions (e.g., NaCl), enabling cost-effective long-term use.
Complies with global potable water standards including NSF/ANSI 61 and EU Drinking Water Directive requirements.
Drinking water treatment for targeted nitrate reduction in municipal and decentralized systems.
Groundwater remediation where agricultural runoff causes elevated nitrate contamination.
Pre-treatment for reverse osmosis and electrodialysis units to protect membranes from nitrate fouling.
Pharmaceutical process water polishing requiring ultra-low nitrate levels.
Food & beverage production water conditioning, especially for infant formula and sensitive product lines.
