FA301 Weak Base Anion Macroporous


FA301 is an extremely durable high capacity, shock resistant, tertiary amine macroporous weak base anion exchange resin with very good
rinse characteristics that can be efficiently regenerated with a variety of alkaline chemicals, or with waste caustic left over from
regeneration of strong base anion resin.
FA301 is intended for use in multibed demineralizers. It can also be used in resource recovery systems and for selective ion removal.
