Cation Exchange Resin Lewatit S-1467
Lewatit® S 1467 is a strongly acidic cation exchange resin with beads of uniform size (monodisperse) based on a styrene-divinylbenzene copolymer. The monodisperse beads are chemically and osmotically very stable. The optimized kinetics lead to an increased operating capacity compared to ion exchange resins with heterodisperse bead size distribution.
Lewatit® S 1467 is especially applicable for:
» softening of industrial water
» softening of drinking water
Lewatit® S 1467 is adding special features to the resin bed:
» high exchange flow rates during regeneration and loading
» good utilization of the total capacity
» low rinse water demand
» homogeneous throughput of regenerants, water and solutions; therefore a homogeneous working
» nearly linear pressure drop gradient for the whole bed depth; therefore operation with higher bed
Lewatit® S 1467 complies with current German legislation on food and food-contact uses and is chemically
in compliance with the FDA regulations 21 CFR 173.25 (a).
Lewatit® S 1467 is in compliance with the European Resolution ResAP (2004)3 (superseding the former
Resolution AP (97)1) with regard to Total Organic Carbon (TOC) release according the AFNOR test T
When using Lewatit® S 1467 to treat potable water and the aqueous solutions listed above, special care
should be given to the initial cycles of the new resin. Please refer to recommended start-up conditions
