| Lewatit® UltraPure 1231 MD is a highly crosslinked, macroporous, medium basic anion exchange resin (MBA, with tertiary and quaternary amine groups) with a monodispersed bead (uniform particle) size distribution based on a styrene-divinylbenzene copolymer for the use in WS/VWS system for the production of ultra pure water. The monodisperse beads (uniformity coefficient: max 1.1) are chemically and osmotically highly stable. The optimized kinetics lead to an increased operating capacity and the very low content of fines also results in a low pressure drop compared to ion exchange resins with heterodisperse bead size distribution. For the production of ultra pure water, leaching of organics from Lewatit UltraPure 1231 MD into the treated water is reduced to a level less than 50 ppb. Hence, Lewatit UltraPure 1231 MD is specially recommended fro the demineralization of water to generate ultra pure quality.Information provided by Lanxess. |
