Lanxess LEWATIT® DW 630 Anion Exchange Resin
Categories:	Polymer; Thermoset
Material Notes:	Lewatit® DW 630 is a strongly basic macroporous anion exchange resin (type I) with beads of uniform size (monodisperse) based on polystyrene. 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 sulfate, 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 applicable for: Removal of natural sulfate and carbonate complexes of uranium from potable-water to rest concentrations safely below 10 ppb Removal of natural organic matter (NOM) such as humic acids, fulvic acids, building blocks, carboxylic acids from potable water.
