Highly stable macroporous strong base anion exchange resin with Type I functionalization.
Exceptional chemical and osmotic stability, suitable for demanding regeneration cycles and high chloride environments.
Optimized for superior sulfate and nitrate selectivity in low-sulfate feed waters.
Low total organic carbon (TOC) extractables, minimizing post-treatment contamination risks.
Uniform spherical bead morphology ensuring consistent hydraulic performance and reduced pressure drop.
Pharmaceutical-grade water polishing in purified water (PW) and water for injection (WFI) systems.
Removal of trace anions (e.g., silica, sulfate, nitrate) from ultrapure water (UPW) in semiconductor manufacturing.
Final polishing step in power plant boiler feedwater treatment to meet ASTM D1193 Type I specifications.
Pre-treatment for reverse osmosis (RO) and electrodeionization (EDI) systems requiring low-anion feed.
