AWB 7030D

Weak Base Anion Exchange Resin

DOSHION AWB 7030D resin is a macroporous weak base anion exchange resin with high capacity. It is based on a Styrene-divinylbenzene co-polymer matrix. It is specifically designed to give high throughput and economical operation in both water and non water applications. This resin is designed to give maximum efficiency and reversible removal of the organic fraction that is soluble at the operating pH values. The high reversibility of organics leads to an excellent resistance to fouling and gives protection to the strong base anion resin typically used downstream. The characteristics of AWB 7030D: • Exceptional physical and thermal stability under varied influent conditions. • Excellent resin kinetics leading to higher throughput. • The Macroporous matrix structure ensures effective adsorption of organics and there removal, hence making it suitable for organic removal/ scavenging. • Ideal for thoroughfare and normal regeneration mode.
