Highly stable macroporous polystyrene matrix with uniform bead structure for consistent hydraulic performance.
Optimized for selective removal of heavy metal cations, including Cu²⁺, Ni²⁺, and Zn²⁺, even from low-concentration streams.
Excellent chemical resistance to oxidizing agents, acids, and alkalis, enabling robust operation in demanding industrial environments.
Fast kinetics and high exchange capacity due to engineered functionalization with iminodiacetic acid chelating groups.
Low pressure drop and high mechanical strength, supporting long service life and reduced operational downtime.
Electroplating rinse water treatment for heavy metal recovery and wastewater compliance.
Pharmaceutical process water polishing to meet stringent USP/EP conductivity and metal ion limits.
Electronic-grade ultrapure water (UPW) pretreatment for semiconductor manufacturing.
Hydrometallurgical leach solution purification in battery metal recycling operations.
Food and beverage ingredient water softening where trace metal control is critical for product stability.
