Full Description

The objective of this study was first to evaluate the efficiency of several adsorbents (MIEX,DOWEX-11, DOWEX-MSA, IRA-938, IRA-958 and AMBERSORB) for theirapplication in drinking water treatment of high dissolved organic carbon (DOC) content surface waters (DOC 6 mg/L).In a parallel study, the impact on mineral ion content was studied with all theresins. The main part of the study focused on MIEX performance. The efficiency of themagnetic anion exchange resin MIEX for natural organic matter (NOM) removal (UV absorbance at 254 nm, DOC,fluorescence emission, HPLC/SEC/UV) was thus tested on raw water, raw water treated bycoagulation-flocculation (ferric chloride with controlled pH and Aqualenc) and ozonatedwater. In the parallel study, the impact on mineral ion content was also studied withall the resins. Finally, the effect of MIEX treatment on membrane fouling was investigatedduring ultrafiltration (100 kDa). Includes 3 references, table, figures.
