High-capacity calcium-selective chelating resin with optimized macroporous matrix for enhanced kinetics and fouling resistance.
Exceptional stability in acidic and oxidative environments, enabling robust performance in challenging process conditions.
Uniform spherical bead morphology ensures low pressure drop and consistent hydraulic flow distribution in fixed-bed systems.
Low soluble organic carbon (SOC) release, meeting stringent requirements for ultrapure water and pharmaceutical-grade applications.
Regenerable with standard acid solutions (e.g., HCl or H₂SO₄), supporting sustainable operation and reduced chemical consumption.
Removal of calcium and heavy metal ions from industrial process water and rinse streams.
Polishing step in ultrapure water (UPW) systems for semiconductor manufacturing.
Pre-treatment for reverse osmosis (RO) feedwater to prevent scaling and membrane fouling.
Recovery and purification of metal-bearing effluents in electroplating and metal finishing operations.
Calcium softening in high-purity boiler feedwater and steam generation systems.
