In this paper, natural organic matter (NOM) fraction removal by different anion exchange (IEX) resins was
studied, as well as the effect of NOM removal on the performance of activated carbon filtration. Surface
water from the Weesperkarspel treatment plant (WPK) was used for batch experiments. Samples taken
before and after treatment with resin and granular activated carbon (GAC) were analyzed by measuring
dissolved organic carbon (DOC) and ultraviolet (UV) absorbance at 254 nm (UVA254). In addition, NOM
characterization was done by fluorescence excitation emission matrix (EEM) and liquid chromatography
with organic carbon detection (LC-OCD). By determining Freundlich isotherms, predictions of running
times of IEX and GAC filters were made. Lewatit VP OC 1071 and MIEX DOC resin were the best
performing resins. By first removing NOM with those resins, the life times of GAC filters will
increase by a factor of 10, for DOC removal. Includes 15 references, tables, figures.
