Highly stable macroporous polystyrene-divinylbenzene matrix engineered for superior mechanical and osmotic shock resistance.
Optimized uniform bead size distribution ensures low pressure drop and consistent hydraulic performance in fixed-bed systems.
Exceptional chemical stability across wide pH range (0–14), enabling reliable operation in aggressive regeneration environments.
Low fines generation and high attrition resistance prolong column service life and reduce operational downtime.
Designed for efficient removal of multivalent anions including sulfate, nitrate, chromate, and arsenate from process streams.
Removal of sulfate and nitrate from industrial wastewater prior to discharge or reuse.
Polishing step in pharmaceutical water systems (PW/WFI) for trace anion control.
Treatment of flue gas desulfurization (FGD) blowdown to meet stringent sulfate discharge limits.
Pre-treatment for reverse osmosis systems to prevent scaling by multivalent anions.
Recovery and separation of valuable anions (e.g., molybdate, tungstate) in hydrometallurgical processes.
