title: Trihalomethane determination and removals from the main discharge channel of Konya City (Turkey).
abstract: Konya Main Discharge Channel is a very important environmental problem due to carrying the domestic waste water of Konya city centre as well as industrial waste water. Lowest flow rate of the channel was observed in October about 2 10(4) m3d(-1). In this period, channel water is not only waste water but includes more rain water coming from Gölyazi region. Discharge channel water can only reach to Tuz Lake for three months in a year. At other times of the year, water cannot reach the lake because of high evaporation, infiltration and usage of the water for irrigation. The land irrigated with the waste water tends to lose its productivity. In this study, water samples were collected and analysed from one hourly period for 2 days (24 x 2 = 48), daily period for 3 weeks (7 x 3 = 21) and monthly samples for a year (9 months). The samples were analysed as to whether these contained trihalomethanes or not, also results were compared with disinfection method that is used for drinking water, and samples were collected from ten different points on the channel. Pollution level of the channel water was controlled in accordance with the Turkish Water Pollution Control Law. In addition to trihalomethanes analysis, the effect of aeration on trihalomethanes was investigated. Collected samples (given above) were analysed for trihalomethanes compounds, and the relationship between disinfection type and dosage method on trihalomethanes formation was compared in this study.
