In sewer systems where anaerobic conditions are present, sulfate-reducing bacteria reduce
sulfate to hydrogen sulfide (H 2 S), leading to sewer corrosion and odor emission. Various …

Concrete corrosion is one of the most significant problems affecting valuable sewer
infrastructure on a global scale. This problem occurs in the aerobic zone of the sewer, where …

Natural Ventilation (NV) contributes to the energy performance and Indoor Air Quality (IAQ)
of existing buildings and Nearly Zero Energy Buildings (NZEB). To predict and validate the …

Sewers are known as longitudinal reactors where gases such as methane, nitrous oxide and
hydrogen sulphide can be produced. However, gaseous emissions have been mainly …

Understanding hydrogen sulfide (H 2 S) emission into sewer air space and the rate of
ventilation to the atmosphere is important in preventing/mitigating odor and corrosion …

Quantifying greenhouse gas (GHG) emissions from the conveyance of wastewater is an
essential part of emissions reduction as it can identify areas of high emissions that can be …

Modeling air movement in sewer systems is important because of its importance in
addressing sewer odor issues and pipe corrosion. In this study, a steady-state model was …

An extensive measuring campaign targeted on sewer odor problems was undertaken in San
Francisco. It was assessed whether a conceptual sewer process model could reproduce the …

Current designs of sanitary collection systems normally only consider the transport of
wastewater without attention on the air movement in the sewer airspaces. Under anaerobic …

Hydrogen sulfide (H 2 S) is one of the sewer gases commonly found in wastewater
collection systems. This anaerobic degradation product causes issues, ranging from odor …
