GA 12
Demineralization Resin
Strong Base Anion (Gel)
DOSHION GA 12 is a GEL Type -II Strong Base Anion Exchange Resin with high capacity. It is based on cross-linked polystyrene matrix. DOSHION GA 12 is specially designed to give high throughput and economical operation. The basicity of this Type – II resin is lower than that of the Type – I resin and the hydrophilicity of the Type- II resin is higher than that of the Type – I resin
DOSHION GA 12 is recommended for demineralisation, oxygen removal and nitrate removal. The resins are highly resistant to osmotic shocks and attrition losses and are adaptable for both counter-current and co-current operations.
