Highly selective chelating resin with iminodiacetate functional groups for preferential binding of heavy metal ions.
Exceptional chemical and osmotic stability across broad pH range (1–12), enabling robust performance in aggressive regeneration environments.
Optimized bead uniformity and mechanical strength to minimize pressure drop and resist attrition in continuous industrial service.
Low sodium leakage and high regeneration efficiency, reducing rinse water consumption and operational costs.
Compliant with FDA 21 CFR §173.25 for indirect food contact applications when properly regenerated and rinsed.
Removal of copper, nickel, zinc, cobalt, and cadmium from electroplating rinse waters and metal finishing effluents.
Recovery of valuable metals from hydrometallurgical leachates and spent catalyst solutions.
Pretreatment of boiler feedwater and ultrapure water systems to eliminate trace transition metals that catalyze corrosion.
Polishing step in pharmaceutical water systems (PW, WFI) to meet stringent USP <731> and EP 2.2.48 metal limits.
Decolorization and metal ion stabilization in sugar refining and organic acid production streams.
