Highly selective for divalent cations including Ca²⁺, Mg²⁺, and heavy metals in complex water matrices.
Optimized macroporous acrylic matrix providing excellent chemical and osmotic stability across wide pH and temperature ranges.
Low pressure drop and high hydraulic throughput due to uniform spherical bead morphology and narrow particle size distribution.
Regenerable with standard acid solutions (e.g., HCl or H₂SO₄), enabling cost-effective cyclic operation.
Complies with global food-contact and potable water standards including FDA 21 CFR §173.25 and EU Regulation (EC) No 1935/2004.
Removal of hardness ions and trace heavy metals from municipal and industrial process water.
Pretreatment for reverse osmosis and electrodeionization systems in high-purity water production.
Recovery and concentration of valuable metal ions (e.g., Ni²⁺, Co²⁺, Cu²⁺) in hydrometallurgical effluents.
Polishing step in pharmaceutical-grade purified water (PW) and water-for-injection (WFI) systems.
Decolorization and organic load reduction in sugar refinery and beverage industry wastewater streams.
