AmberLite™ HPR8400 H Ion Exchange Resin is an Acrylic, Macroporous, Weak Acid Cation Exchange Resin for Industrial Demineralization, Softening, and Dealkalization Applications. It is a high-quality resin for use in industrial demineralization and softening applications when high performance and cost-effective operation is required. The exceptionally high total capacity and the larger particle size of the resin help yield excellent operating capacity with low pressure drop, while reducing chemical regenerant and water usage. When AmberLite HPR8400 H is operated in the Na form, it will remove total hardness even in high salinity waters. 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 HPR8400 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 HPR8400 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 HPR8400 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.
