AWB 7020D

Weak Base Anion Exchange Resin

DOSHION AWB-7020D resin is a Macroporous Weak Base Anion Exchange Resin with very high capacity. It is based on a styrene-divinylbenzene co-polymer matrix. DOSHION AWB-7020D resin is specifically designed to give high throughput and economical operation in both water and non water applications. DOSHION AWB-7020D resin is designed to give maximum efficiency and reversible removal of that organic fraction that is soluble at the operation pH values. The high reversibility to organics leads to an excellent resistance to fouling and gives protection to the strong base anion resin typically used downstream. The Characteristics of AWB-7020D: • Exceptional physical and thermal stability under varied influent conditions. • Excellent resin kinetics leading to higher throughput. • The macroprous matrix structure ensures effective adsorption of organic and their removal, hence making it suitable for organic removal/scavenging. • Ideal for thoroughfare and stand alone regeneration mode.
