DuPont™ AmberLite™ HPR4700 OH

AmberLite™ HPR4700 OH Ion Exchange Resin is a Uniform Particle Size, Gel, Strong Base Anion Exchange Resin for Condensate Polishing for the Power Industry and Industrial Demineralization Applications. It is specifically designed for use in condensate polishing beds at fossil-fired electric generating stations and industrial demineralization applications when a balance of operating performance, simple operation, long resin life, and cost-effective operation is required. A faster startup can be achieved with a strong base anion exchange resin delivered in the OH-form by providing higher water quality combined with lower TOC throw from startup, compared to the Cl-form. This resin provides good bead integrity and rapid exchange kinetics due to its small average particle size, making it ideally suited to the high flowrate demands commonly encountered in power plant condensate polishing systems. The bead size uniformity and a distinguishable light color is tailored to complement the larger, denser, cationic, gel AmberLite™ HPR1300 H Ion Exchange Resin, offering exceptional separation in mixed beds. The color distinction between this pair of resins allows easy visual confirmation of separation following backwash. For post-RO mixed bed polishing with a strict silica specification and/or the need to maximize silica removal capacity, AmberLite HRP4700 OH is an ideal choice. AmberLite HPR4700 OH can also be used in single-bed demineralization applications when organic loading is not a limiting factor.
