High-capacity calcium-selective chelating resin with optimized macroporous matrix for superior kinetics and fouling resistance.
Exceptional chemical and thermal stability in acidic, alkaline, and oxidizing environments up to 80 °C.
Low operating pressure drop and high mechanical strength, ensuring long service life in fixed-bed and moving-bed systems.
Consistent particle size distribution (0.45–1.25 mm) for uniform flow dynamics and minimized channeling.
Regenerable with dilute mineral acids or calcium chloride solutions, enabling cost-effective cyclic operation.
Removal of heavy metals (e.g., Ni²⁺, Cu²⁺, Zn²⁺, Cd²⁺) from industrial wastewater streams.
Calcium and magnesium softening in pre-treatment for reverse osmosis and boiler feedwater systems.
Recovery and concentration of valuable metal ions in hydrometallurgical leachate purification.
Polishing of process water in pharmaceutical and electronics manufacturing where ultra-low ionic contamination is required.
Selective separation of transition metals in catalyst regeneration and battery recycling effluents.
