Weak Base High Porous Anion(EA-WM)
Ecologix Systems' US Resin A-WM (free-base or OH form) resin is a high capacity, organic-fouling resistant porous gel Type I weak base anion exchange resin.
It can be used in the preparation of pure water, especially for water source with higher salt and organic content. It is also used in treating electroplating wastewater to recover chromium.
Typical Physical, Chemical & Operating Characteristics
Chemical and Thermal Stability
Ecologix Systems' EA-WM resin is insoluble in dilute or moderately concentrated acids, alkalies, and in all common solvents. However, exposure to significant amounts of free chlorine, “hypochlorite” ions, or other strong oxidizing agents over long periods of time will eventually break down the crosslinking. This will tend to increase the moisture retention of the resin, decreasing its mechanical strength, as well as generating small amounts of extractable breakdown products. It is thermally stable to 100oC (210 oF). The OH form resin is recommended for application temperature lower than 65oC (150 oF).
