Lewatit®

LEWATIT® DW 630

Lewatit® DW 630 is a macroporous, monodisperse, polystyrene-based strongly basic anion exchange resin (type I). The resin has been thoroughly washed with sulfuric acid and water to assure potable water purity grade.

Lewatit® DW 630 will not significantly exchange any major water constituents (Cl-, HCO3 -, NO3 -) because it is loaded with sulphate, which has the highest selectivity among these anions. Therefore the water composition will not be changed except the removal of target impurities.

On account of its fast kinetics, high total capacity, good chemical stability, osmotic properties and porosity Lewatit® DW 630 is especially suitable for:

  • removal of natural sulfate and carbonate complexes of uranium from potable water safely below rest concentrations below 10 ppb
  • removal of natural organic matter (NOM) such as humic acids, fulvic acids, organic building blocks, carboxylic acids from potable water

Potable water approval certifications are country specific and available as manufacturer's declaration upon request.

In case Lewatit® DW 630 is used for potable water treatment a special start-up procedure has to be applied. This information is available upon request.
