LEWATIT® MDS TP 208

Lewatit® MDS TP 208 is a weakly acidic, macroporous cation exchange resin with chelating iminodiacetic acid groups designed for the selective removal of alkaline earth cations. lt is a small bead variant of Lewatit® MonoPlus TP 208 with excellent kinetic performance.
The monodisperse, uniform sized beads of Lewatit® MDS TP 208 are mechanically and osmotically more stable than ion exchange resin beads with heterodisperse bead size distribution. Additionally they offer superior kinetic behavior which leads to faster uptake of cations and a better utilization of capacity. Due to its modified polymer structure and substitution grade it is particular suitable for the adsorption of alkaline earth and heavy metal cations from diluted and concentrated brine solutions. Therefore Lewatit® MDS TP 208 is commonly used for following application:

• Fine polishing of brine fed to chloralkali membrane cells, e.g. by removal of Ca², Mg², Sr²; also in the presence of Fe³⁺ ions
