Highly selective for potassium (K⁺) and ammonium (NH₄⁺) ions in complex aqueous matrices.
Stable macroporous polystyrene-divinylbenzene matrix ensures excellent mechanical strength and pressure resistance.
Optimized particle size distribution (0.3–1.2 mm) enables low-pressure-drop operation in fixed-bed and column systems.
Chemically resistant to oxidants, acids, and bases within standard pH range (0–14), supporting robust regeneration cycles.
Low fines generation and high attrition resistance prolong service life and reduce system fouling.
Ammonium removal from municipal and industrial wastewater prior to discharge or reuse.
Potassium recovery and concentration in food processing effluents and fermentation broths.
Softening and selective ion removal in pharmaceutical water purification systems (PW/WW).
Nutrient recovery (K⁺/NH₄⁺) in agricultural runoff and anaerobic digester liquors.
Pre-treatment for reverse osmosis (RO) and electrodialysis reversal (EDR) to prevent scaling and membrane fouling.
