Title: | Effects of water matrix and ozonation on natural organic matter fractionation and corresponding disinfection by-products formation | Authors: | Agbaba Jasmina Molnar Jazić Jelena Tubić Aleksandra Watson Malcolm Maletić Snežana Dalmacija Božo |
Issue Date: | 2015 | Journal: | Water Science and Technology: Water Supply | Abstract: | © 2015 IWA Publishing. In this study the influence of water matrix and oxidation treatment by ozone on natural organic matter (NOM) fractionation and corresponding disinfection by-products formation was investigated. Three water types were selected, based on their different NOM contents (5.16-9.85 mg/L dissolved organic carbon (DOC)) and structures (42-79% proportion of hydrophobic NOM fraction). It was determined that increasing the ozone dose (0.2-0.8 mg O3/mg DOC) generally led to reductions in DOC (2-26%) and trihalomethane formation potential values (4-58%). Results of NOM fractionation showed that the reactivity of all the individual NOM fractions towards trihalomethane formation decreased after ozone oxidation (0.8 mg O3/mg DOC) by 47-69%, relative to the raw waters. | URI: | https://open.uns.ac.rs/handle/123456789/30421 | ISSN: | 1606-9749 | DOI: | 10.2166/ws.2014.086 |
