Doing so, it is important to use modeling tools that are capable of assessing variations of dissolved oxygen, dissolved sulfide and hydrogen sulfide gas concentrations for a wide range of environmental scenarios. Two such models were assessed: AEROSEPT, an empirical formulation, and WATS, a conceptual and more complex approach. The models were applied to evaluate the effects of transitions between pressure mains and gravity sewers in the air\u2013liquid mass transfer of hydrogen sulfide at the Ericeira sewer system in Portugal. This network is known to have odor and corrosion problems, especially during summer. Despite the unavoidable uncertainties due to the unsteady flow rate and the quantification of air velocity and turbulence, the simulation results obtained with both models have been shown to adequately predict the overall behavior of the system.<\/jats:p>","DOI":"10.2166\/wst.2017.595","type":"journal-article","created":{"date-parts":[[2017,11,24]],"date-time":"2017-11-24T01:10:46Z","timestamp":1511485846000},"page":"777-787","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":10,"title":["Release of hydrogen sulfide under intermittent flow conditions \u2013 the potential of simulation models"],"prefix":"10.2166","volume":"77","author":[{"given":"Nat\u00e9rcia","family":"Matias","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Architecture and Georesources (DECivil) & Civil Engineering Research and Innovation for Sustainability (CERIS), Instituto Superior T\u00e9cnico (IST), University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rita","family":"Matos","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Architecture and Georesources (DECivil) & Civil Engineering Research and Innovation for Sustainability (CERIS), Instituto Superior T\u00e9cnico (IST), University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filipa","family":"Ferreira","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Architecture and Georesources (DECivil) & Civil Engineering Research and Innovation for Sustainability (CERIS), Instituto Superior T\u00e9cnico (IST), University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jes","family":"Vollertsen","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Aalborg University, Sofiendalsvej 11, DK-9200 Aalborg SV, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Saldanha","family":"Matos","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Architecture and Georesources (DECivil) & Civil Engineering Research and Innovation for Sustainability (CERIS), Instituto Superior T\u00e9cnico (IST), University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","published-online":{"date-parts":[[2017,11,23]]},"reference":[{"key":"2020032810595058100_WST-EM171007R1C1","volume-title":"Sulfide in Wastewater Collection and Treatment Systems","author":"ASCE (American Society of Civil Engineers)","year":"1989"},{"key":"2020032810595058100_WST-EM171007R1C2","unstructured":"Engidro, HIDRA & Aquapor 2015 Master Plan for Sanitation and Drainage of the Metropolitan Area of Maputo - Analysis of the Existing Situation.
