Strong base anion resin type I as a single resin is particularly recommended for treating low FMA (Free Mineral Acid) water with high silica and where low silica leakage is required (-20 ppb in counter-current operation). The resin can be regenerated up to 50°C (122°F) for more effective silica removal. DOWEX™ MARATHON™ A A resin is designed for general demineralization and for UPCORE™ system plants, the resins are DOWEX UPCORE Mono A-500 or DOWEX UPCORE Mono A-625 resin.
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 an ideal choice for the UPCORE system.
