All
surface and ground waters include natural organic matter (NOM). During the
disinfection NOM reacts with chlorine and forms various types of halogenated
disinfection by-products (DBPs). There are lots of study in the literature
about these possible carcinogenic effects on human. Trihalomethanes (THMs) and
haloacetic acids (HAAs) are the most widely known and most produced DBPs. But
there lots of different types of DBPs occurred after the disinfection and
sometimes absorbable organic halogens (AOX) measurement can be used for
determining the total amount of DBPs. In this study raw water samples were
taken from Büyükçekmece (BC) and Ömerli (OM) surface water sources in the
seasonal basis. At the first stage water quality parameters were analysed and
then samples were chlorinated. After 7 days reaction period THMs, HAAs,
haloasetonitrilles (HANs), chloral hydrate (CH), chloropicrin (CP) and AOX
measurements were conducted and according to these results undefined DBPs
percentage of AOX was calculated. In terms of OM and BC raw water undefined
portion of AOX was averagely calculated as 59.4% and 58% respectively.
