Felite™ FA124 is a highly porous, gel, Type I, strong base anion resin, supplied in the chloride form as moist, tough, uniform spherical beads, supplied in Cl form. It has greater porosity, and this provides superior regeneration efficiency, easier separation in regenerable mixed beds, and greater resistance to organic fouling. FA124-OH resins in combination with FC108-H (strong acid cation resin) give excellent performance in mixed beds.

Felite™ FA124 is intended for use in the hydroxide form for all types of deionizing systems as well as in the chloride form for removal of both strong and weak acid radicals such as sulfate, nitrate, arsenate, chromate, and silicate to extremely low concentration levels.

Principal Application:
