AMBERLITE™ IRA67RF

Industrial Grade Weak Base Anion Exchanger

Introduction

    AMBERLITE IRA67RF resin is a weak base anion exchange resin with a gel type acrylic matrix. It has a high capacity, excellent physical stability, fast kinetics, outstanding resistance to organic fouling and basicity higher than that of polystyrenic weak base resins. The flexible acrylic structure of AMBERLITE IRA67RF resin allows for effective adsorption and desorption of naturally occurring organic molecules, such as humic and fulvic acids, that are present in many water supplies. The particle size distribution of AMBERLITE IRA67RF resin has been specifically selected to give optimum performance in packed bed and floating bed applications.

Hydraulic Characteristics

    AMBERLITE IRA67RF resin gives a pressure drop of about 10 kPa/m bed depth per 10 m/h at 15 °C. A backwash flow rate of 6.5 m/h gives a bed expansion of about 65 % at 15 °C.
