“…To differentiate the types of DBP in everyday activity of Ufavodokanal-a water treatment station in Ufa (Russia)-the following integrated indices of water quality were developed and introduced into practice: technogenic organic carbon (TgOC), technogenic organic chlorine (TgOCl), technogenic organic bromine (TgOBr) and technogenic organic oxygen (TgOO) in semi-volatile organic compounds (SVOCs) with boiling points in the range of 150-500 • C, isolated from water by liquid-liquid extraction [58].…”

The main drawback of drinking water chlorination involves the formation of quite hazardous disinfection by-products (DBPs), represented mainly by halogenated species. Based on the authors’ monitoring data since 2002, the prevalence of chlorine over bromine in the composition of volatile DBPs was shown for the drinking water in Ufa (Russia). However, the situation was completely reversed in the case of semi-volatile DBPs. The principal goal of the present study involved rationalization of the results of the long-term monitoring. Gas chromatography–mass spectrometry (GC-MS) was used for the qualitative and quantitative analysis of volatile DBPs. Identification of semi-volatile compounds was carried out with GC-MS, while gas chromatography with an atomic emission detector (GC-AED) was used for their quantification. A significant contribution of oxygen to the composition of semi-volatile compounds proves the decisive role of the dissolved organic matter oxidative destructive processes. Statistical analysis revealed notable linear correlations for trihalomethane and haloacetic acid formation vs. chlorine dose. On the contrary, halogenated semi-volatile products do not demonstrate any correlations with the water quality parameters or chlorine dose. Principal component analysis (PCA) placed them into separate groups. The results allow for proposing that formation of the organohalogenated species involved the fast penetration of bromine into the humic matter molecules and, further, their oxidative destruction by active chlorine.

“…In order to find ways to manage water treatment technology, cluster analysis of different quality indicators of raw water of the Ufa river (prior to treatment) and potable water was conducted. The indicators analyzed were: turbidity, chromaticity, permanganate index, dissolved organic carbon (DOC) of raw water; specific ultraviolet absorbance at 254 nm (SUVA) of raw and potable water; and concentrations of byproducts of water chlorination, such as trihalomethanes (THM), haloacetic acids (HAA) and halogenated semi-volatile organic compounds (SVOC) [1,2]. The sample size was 200 measurements carried out in five years.…”
