AmberLite™ Ion Exchange Resins


DuPont™ AmberLite™ IRC83 H


AmberLite™ IRC83 H Ion Exchange Resin is a Gaussian, Acrylic, Macroporous, Weak Acid Cation Exchange Resin for Industrial Demineralization, Softening, and Dealkalization Applications. It is a general-purpose dealkalization and softening resin with a long-established track record of reliable performance in the industry. This industry-staple resin is designed for co-flow regenerated systems in variety of industrial water treatment applications. When AmberLite™ IRC83 H is operated in the Na-form, it will remove total hardness even in high salinity waters such as those in oilfield SAGD systems. When operated in the H-form, it will remove only the hardness associated with alkalinity—a weak acid cation resin operated in the H-form is well-suited for use with strong acid cation resins to improve overall efficiency and throughput of a demineralization system by reducing the hardness exposure on the strong acid cation resin. In Na-form softening operation, AmberLite™ IRC83 H enables improved operating capacity for total hardness versus other weak acid cation resins currently available, which allows more competitive vessel design or extended production capacity when installed in existing systems. In dealkalization, AmberLite™ IRC83 H has demonstrated improved operating capacity versus other weak acid cation resins currently available, which allows users to simultaneously minimize operating costs and environmental impacts while also preserving precious raw water resources under the right conditions. In reverse osmosis pretreatment, AmberLite™ IRC83 H can protect the membrane from hardness scaling, which can improve system recovery and operational reliability and can eliminate the use of chemicals such as antiscalants or acids for RO feedwater pH control. The resin’s ability to soften high-salinity feedwaters enables the RO to reliably operate under extremely variable and/or harsh conditions, such as with wastewater reuse or minimal liquid discharge.
