Highly selective for heavy metal ions including Cu²⁺, Ni²⁺, Zn²⁺, and Cd²⁺ in acidic to neutral pH ranges.
Exceptional chemical and physical stability in aggressive industrial effluents containing oxidants and moderate organic loadings.
Optimized macroporous polyacrylic matrix providing rapid kinetics and low pressure drop during service cycles.
Regenerable with dilute acid solutions (e.g., 2–5% H₂SO₄ or HCl), enabling sustainable closed-loop operation.
Low soluble organic leaching and minimal fines generation, ensuring long-term column integrity and effluent compliance.
Removal of toxic heavy metals from electroplating rinse waters and metal finishing wastewater.
Treatment of mining leachates and acid mine drainage prior to discharge or resource recovery.
Polishing step in hydrometallurgical processes for high-purity nickel, cobalt, and copper electrolyte streams.
Pre-treatment of process water in semiconductor manufacturing to meet ultra-low metal specifications.
Decentralized on-site treatment systems for small-to-medium industrial facilities with variable flow and composition.
