dc.description.abstract | Laboratory studies using ozone oxidation were conducted on samples of groundwater. The effects of ozonation on natural organic matter (NOM), color, and trihalomethane formation potential (THMFP) were examined. The fourteen groundwater samples had dissolved organic carbon (DOC) concentrations between 0.9 and 14.4 mg/L and color levels between 13 and 210 pcu. Small doses of ozone appeared to result in an oxidative polymerization phenomenon whereby the apparent molecular weight (AMW) of the organics increased. Higher doses of ozone led to lower AMW organic matter. Ozonation was successful at destroying color and ultraviolet absorbance at 254 nm. Ozonation showed limited ability to remove THMFP. Ozone treatment prior to chlorination resulted in increased brominated THMs. | |
