Highly selective for multivalent cations including calcium, magnesium, and heavy metals.
Exceptional chemical and osmotic stability across broad pH range (1–14) and high salt concentrations.
Optimized macroporous structure ensures rapid kinetics and minimal pressure drop in service cycles.
Low fines generation and excellent mechanical strength for extended column life and reduced backwash requirements.
Regenerable with standard acid solutions (e.g., HCl or H₂SO₄), enabling cost-effective reuse in closed-loop systems.
Removal of hardness ions (Ca²⁺/Mg²⁺) in industrial boiler feedwater pretreatment.
Recovery and purification of transition metals (e.g., Ni²⁺, Cu²⁺, Co²⁺) from electroplating rinse streams.
Decontamination of process water in pharmaceutical manufacturing to meet USP/EP conductivity limits.
Pre-concentration of rare earth elements (REEs) from low-concentration leachates in hydrometallurgical operations.
Polishing step in ultrapure water (UPW) systems for semiconductor fabrication facilities.
