DESCRIPTION |
Purolite A300E is a Type II strong base anion exchange resin with a gel polystyrene-divinylbenzene matrix. It features a high operating capacity and is specifically designed for efficient removal of strongly ionized acids and silica from water in demineralization systems, offering excellent regeneration efficiency.
Water Demineralization: Primary application in multi-bed or mixed-bed deionization systems for industrial water treatment.
Silica Removal: Effectively removes silica and other weakly ionized acids from process water.
Industrial Process Water: Used in various industries including power generation, chemical processing, and manufacturing.
Condensate Polishing: Applied in power plant condensate treatment systems for high-purity water requirements.
Chemical Processing: Suitable for acid removal and purification in various chemical manufacturing processes.
Manufacturer: Purolite
