Felite™ FA225 is a gel-type strong base anion exchange resin containing Type II quaternary ammonium groups. It has high capacity, high chemical efficiency and good resistance to fouling, and is intended for use in the chloride form for removal of contaminants such as nitrate, arsenate, chromate, uranium, etc., as well as in the hydroxide form for all types of deionizing systems.

Felite™ FA225 in the hydroxide form is especially well suited for use for systems where amine odors might be objectionable.
