GA 11

Strong Base Anion Exchange Resin Type - I

DOSHION GA-11 resin is a GEL Type-1 Strong Base Anion Exchange resin with high capacity. It is based on polystyrene matrix with quaternary ammonium functional groups. DOSHION GA-11 is specially designed to give high throughput and economical operation in both water and non water applications. DOSHION GA-11 resin in combination with DOSHION CSA-9 resin, gives outstanding separation and performance in mixed beds.
The resin is supplied in hard moist bead forms and is suitable for both Co-current and Counter current operation. GA-11 is best suited for achieving lowest possible silica leakages in treated water.
