Abstract

The presence of sulfur in sewage sludge from the Barueri Sewage Treatment Plant (STP) seems to be related to the presence of surfactants and feces, both present in domestic wastewater. The results obtained demonstrate a possible correlation with combustion of fossil fuels, that show by isotopic sulfur analyses and results in sewage sludge samples. Fertilizers are also present in the soils due to transport by fluvial and pluvial waters. The reducing environment at anaerobic treatment may have favored the formation of elemental sulfur identified in this study. Its presence was indicated using X-ray diffraction patterns, and point analyses of crystals present in the sewage sludge confirmed its presence by energy dispersive system (EDS) analysis using a scanning electron microscopy (SEM).
