Summary: Industrial and domestic wastewater treatment plants (WWTPs) are associated with environmental
impacts to air quality in neighborhood communities. WWTPs are important sources of odorous
gasesto the atmosphere as nitrogen, sulfur, and volatile organic compounds (VOC). These odorous
gases may cause adverse effects on human health, annoyance which can turn into complaints to
authorities and price depreciation of properties. WWTPs are characterized by large areas
representing fugitive sources of odorous gases (BOCKREIS; STEINBERG, 2005; CAPELLI et
al., 2013; LUCERNONI; CAPELLI; SIRONI, 2017). WWTPs units with passive liquid surface,
for instance, primary and secondary settlement tanks, non-aerated sequencing batch reactors,
equalization tanks, aerated biological filters and stabilization ponds, are potential sources of odour
emissions due to volatilization of dissolved odorants in the liquid phase driven by the interaction
between the liquid-phase and the sweeping wind.
