The primary objectives of this study were to determine the relative effectiveness of the MIEX®,coagulation and enhanced coagulation treatment processes for the removal of dissolved organiccarbon (DOC) from the water, and their effects on the biological stability, chlorine demand andtrihalomethane formation potential (THMFP) of the treated water. The proportions of varioussub-fractions of DOC (i.e., assimilable organic carbon (AOC) and UV<sub>254</sub>-active DOC) that wereremoved at each step of the treatment process were determined. The change in the molecularweight distribution of the UV<sub>254</sub>-active DOC at each step during the treatment process wasdetermined using high performance size exclusion chromatography (HPSEC). Includes 10 references, figures.
