202 Type II Strong Base Anion Exchange Resin
202 Type II Strong Base Anion Exchange Resin
202 is an industrial grade, polystyrenic, gel, type II strong base anion exchange resin normally supplied in the chloride form but also available in the regenerated hydroxide form as 202 OH. Its principal application is in water demineralization. Like all strong base anion resins, the resin swells between the exhausted and regenerated form. This must be taken into account in any design calculations.
Strong base type II anion resins have a higher operating capacity compared to other strong base anion resins. They can achieve very good silica removal and in co-flow regenerated plants they offer slightly higher silica leakage than type I resins. They do not have the same resistance to organic fouling offered by acrylic strong base resins or the temperature stability associated with polystyrenic strong base type I resins when operated in the hydroxide form. They are not so commonly employed in hot climates or other situations when warm water is encountered, e. g. where the raw water is preheated. 202 resin is therefore most widely found in anion units treating waters with a high TDS content. On exhaustion, the resin can be regenerated with a dilute solution of sodium hydroxide.
