Strong Base Anion Resin, Type II

Strong base anion resin type II is well suited for small plants, owing to its excellent regeneration efficiencies for water compositions where CO₂ and SiO₂ are <30% of the total feed anions. Type II anions have a much better operating capacity and regeneration efficiency compared to Type I, but are limited to lower temperature operation (<35°C/95°F caustic treatment) and have a higher SiO₂ leakage (~50 ppb in counter-current operation.) DOWEX™ MARATHON™ A2 resin is the resin of choice for general demineralization and DOWEX UPCORE™ Mono A2-500 resin is ideal for the UPCORE system.
