Lewatit® MonoPlus TP 208 is a weakly acidic, macroporous cation exchange resin with chelating iminodiacetic acid groups designed for the selective removal of alkaline earth cations.

The monodisperse, uniform sized beads of Lewatit® MonoPlus TP 208 are mechanically and osmotically more stable than ion exchange resin beds 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® MonoPlus TP 208 is standardly 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 Fei" ions

Aside from its major application in brine purification Lewatit® MonoPlus TP 208 is used for the removal and recovery of heavy metals out of process, waste and potable water streams.

Those metal cations are removed from neutralized waters in following order (decreasing affinity):

Copper > Vanadium (V02') > Uranium (U0221 > Lead > Nickel > Zinc > Cadmium > Cobalt > Iron (II) > Beryllium > Manganese » Calcium > Magnesium > Strontium > Barium >>> Sodium.
