“…Toluene is a compound that often occurs in municipal and industrial effluents in the range from at detectable levels to ~86 μg/L ( Bell et al, 1988 ; Namkung and Rittman, 1987 ) and higher to ~115 μg/L, for example in raw wastewater at a treatment plant in Skoczow, Poland ( Suschka et al, 1996 ). Toluene, like other volatile organic compounds (VOCs), which include benzene, ethyl benzene, and xylene, in the process of biological treatment are partly biodegraded, or stripped to the atmosphere during aeration ( Zu et al, 1999 ).…”

“…Investigations and measurements of VOCs, particularly BTEX compounds at several municipal wastewater treatment plants (WWTPs), have also shown relatively high concentrations of toluene in the anaerobic digested sludge supernatant. The concentrations of toluene varied over a wide range from 50 to 1760 μg/L ( Suschka et al, 1996 ). The concentration of benzene, ethylobenzene, and xylenes were detected at the lower range 0 to 152 μg/L.…”

“…The concentration of benzene, ethylobenzene, and xylenes were detected at the lower range 0 to 152 μg/L. Also, high concentrations of toluene (15 to 202 μg/m 3 ) have been measured in the ambient air over the open digester tanks at the treatment plant Skoczow, Poland ( Suschka et al, 1996 ). Two open digester tanks are used for the anaerobic digestion processes of wastewater sludge from the primary sedimentation tank and surplus activated sludge at the treatment plant.…”

The formation of toluene in municipal anaerobic primary and secondary sludge digestion processes was investigated. Experiments were carried out in a large laboratory‐scale reactor using sludge from a primary settling tank of a municipal treatment plant. It was found that toluene was produced in the supernatant in relatively large concentrations for almost all cases tested. The concentration of toluene varied and was found to depend on the stage of the anaerobic process. During the acidity phase, which is the first stage of anaerobic digestion, an increase of toluene concentration was observed, while in the transition period, from the acidity phase to methanogenesis, the toluene concentration decreased. It was concluded that biosynthesis of toluene occurs in the acidogenic phase, while biodegradation was prevalent in the methanogenic stage. Depending on the type of experiments, an increase of toluene from a base value of approximately 200 μg/L up to 20 000 and 42 000 μg/L was measured in the first stage of anaerobic digestion. In the subsequent methane‐production stage of digestion, the estimated rate of toluene decrease (biodegradation) varied from 400 to 900 μg/L‐d.

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.

Thermal drying of sewage sludge is a treatment to obtain a material that can be used as co-fuel for some chemical industries, but some volatile organic compounds (VOCs) can be emitted and consequently must be considered. In this work the emissions of these VOCs were studied. The sewage sludge produced by a domestic water treatment plant was dried in a simple laboratory scale distillation/evaporation apparatus at different temperatures (80, 90, 100 and 120 ºC). The sludge was heated and a flow of air released water and volatile compounds. The water was condensed and separated, and the VOCs were analysed in the resultant gas fraction. More than forty compounds were identified and the total yield ranged from 545 to 591 mg kg -1 dry weight, without significant differences for the temperatures used. The compounds with the highest yields were dimethyl disulfide, toluene, dimethyl trisulfide and 1,2,4-trimethylbenzene, with great differences in yields from the rest of the compounds found. Between the compounds identified, several types were found: aliphatic hydrocarbons, aromatic hydrocarbons, halogenated or not, and compounds with sulphur. Since most of the identified VOCs are carcinogenic, toxic or harmful by inhalation, there is a need to control the emitted gases from thermal drying.
