Strong Base Anion Exchange Resin Type - ||

DESCRIPTION: DOSHION ASB-171 is an Isoporous Type-|| Strong Anion Exchange Resin with high is based on cross-linked polystyrene matrix. DOSHION ASB-171 is specially desingend to give high throughput with economical operation cost. Trimethyl amine is used to prepare Type-| resin and dimethyl ethanolamine is used to prepare Type-|| resin. Thus the basicity of the Type-|| resin is lower then that of the Type-| resin and hydrophillcity of the Type-|| resin is higher then that of the Type-| resin.thus the resln is more sutable for higher removal efficlency of Chlorides and Sulphates from feed water. DOSHION ASB-171 is recommended for demineralisation oxygen removal and nitrate removal. The resin is supplied in hard moist bead form and is suitable for co-courrent and counter-current applications in demineralisation system.
