Abstract: Hydrogen sulfide (H2S) is a primary cause of odor and corrosion in sewer systems. In drop structures, falling wastewater impinges the surface of bottom water pool as a jet or numerous drops, triggering a high level of ...

Abstract: In urban drainage systems, falling sewage in drop structures expedites the mass transfer of hydrogen sulfide (H2S) and oxygen (O2). This process is important for sewer odor and corrosion control; however, direct experiments ...

Abstract: Hydrogen sulfide (H2S) is the primary cause of odor and corrosion in sewer systems. When wastewater breaks up into small droplets in drop structures, the emission of H2S is expected to be significantly enhanced relative ...

Abstract: Fieldwork was carried out in the western area of Edmonton, Alberta, Canada to assess the H2S contribution of a long force main and to investigate the source of H2S generation in a complex sewer network. The study sewer ...
