  • Performance of sanitary sewer collection system odour control devices operating in diverse conditions

    Controlling odours from sanitary sewer systems is challenging as a result of the expansive nature of these systems. Addition of oxidizing chemicals is often practiced as a mitigation strategy. One alternative is to remove odorous compounds in the gases vented from manholes using adsorptive media. In this study, odour control devices located at manholes were observed to determine the ability of ...

  • Hydrogen sulfide gas emission under turbulent conditions – an experimental approach for free-fall drops

    Odor nuisance and sulfide corrosion in sewers carrying septic wastewater are accelerated at points of turbulence such as drops in manholes, but accurate methods or empirical expressions to evaluate the gas stripping rate at those particular sites are still missing. With the aim of improving the current knowledge on the influence of free-fall drops on the release of hydrogen sulfide gas, an ...

  • Aerobic and Anaerobic Transformations of Sulfide in a Sewer System – Field Study and Model Simulations

    ABSTRACTThe formation and fate of sulfide in a force main and a downstream-located gravity sewer were investigated in an extensive field study. Sulfide formation during approximately 4 hours of anaerobic transport in the force main was significant. The following gravity sewer was aerobic and a fast reduction of the sulfide concentration was observed due to sulfide oxidation and emission of ...
