Advanced Oxidation Processes to Reduce Odor Emissions from Municipal Wastewater—Comprehensive Studies and Technological Concepts

Municipal facilities can generate odors caused by substances such as fatty acids, organosulfur compounds, aldehydes, and inorganic gases, especially H2S. Identifying an effective cost-efficient solution to the problem is a priority for communities in areas at risk of exposure odors. The aim this study was evaluate effect advanced oxidation processes (AOPs) involving Fenton’s reagents (Fe2+/H2O2, Fe3+/H2O2) on wastewater profiles their capacity reduce putrescibility, H2S emissions, odor concentration air. Fe2+/H2O2 system proved be most efficient terms inhibiting process redox conditions development, removing organic matter wastewater, formation, reducing emissions. generation raw triggered early day 2 anaerobic retention, with levels 5.6 ppm 64 ppm. After introduction 0.1 g Fe2+/dm3 2.0 H2O2/dm3, no detected gas 8 days.
