“…In the present work, significant concentrations of the compounds mentioned by Wilson et al [2] have been observed during the drying of sewage sludge. On the other hand, Webber et al [3] studied a higher number of compounds, twenty-six VOCs, and the results agree with the previous authors, obtaining total concentrations higher than 5 mg kg -1 , where toluene and xylenes predominated. Other authors have studied the emissions of VOCs during sludge dewatering processes by centrifuges and filter press.…”

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.

“…It has been widely used in cropped land especially in Europe, America and some parts of Asia. Its application to soils not only improves organic matter and essential nutrient contents, but also improves soil physical and microbial conditions (Parat et al 2005, Mohammad and Athamneh 2004and Webber et al 1996. However, it may cause a potential hazard, especially heavy metal pollution (Cd, Ni, Cu, Zn and other metals) to soil (Bozkurt andYarilgac 2003, Mohammad andAthamneh 2004).…”

Sewage sludge at the rate of 0, 40, 80, 120 and 240 t/ha showed that the number of filled grains per panicle, dry weight of grains and weight of 1000 grains of rice (Oryza sativa L.) were the significantly highest where 240 tons of sewage sludge per hectare was added. The contents of N, P, K, Ca, Mg, Fe, Cu, Zn and Pb in rice grains increased significantly with increasing rate of sewage sludge application, while that of Mn decreased significantly. Chromium, cadmium and nickel contents in the rice grain were below detection limit.
