Modelling of methane production in a sewer network
نویسندگان
چکیده
An online methane sensor was employed to monitor methane level in the sewage at the end of a rising main for a period of 3 weeks during both winter and summer periods. Based on the sewer information and the pump station operation data, a model was setup for the sewer system. The SeweX model, capable of predicting methane generation in a sewer, was employed for this purpose. The model was calibrated and validated using the measured methane concentrations in summer and winter, respectively. The model was able to reproduce the variation in methane concentration reasonably well suggesting that the model can therefore be used as a tool for greenhouse gas accounting for the wastewater collection system.

Methane formation in sewer systems.
Methane formation and emission in sewer systems has not received as much attention as hydrogen sulphide formation. Through field measurements from two rising mains, with an average sewage temperature of 28.4 and 26.6 degrees C, respectively, at the time of sampling, this study shows that a significant amount of methane can be produced in sewer systems, and that this production is positively cor...
متن کاملAdvanced assessment of Sulfide and Methane emissions from sewers of Mediterranean cities
Production and build-up of sulfide and methane in wastewater collections systems cause several detrimental effects including odour nuisance, health hazards due to its toxicity and corrosion of pipes and inlet structures of sewage treatment plants. On the other hand methane is a greenhouse gas significantly contributing to global warming. Despite these major impacts, sewer-produced sulfide and m...
متن کاملOn-line monitoring of methane in sewer air
Methane is a highly potent greenhouse gas and contributes significantly to climate change. Recent studies have shown significant methane production in sewers. The studies conducted so far have relied on manual sampling followed by off-line laboratory-based chromatography analysis. These methods are labor-intensive when measuring methane emissions from a large number of sewers, and do not captur...

Anaerobic digestion (AD) of biowastes is one of the most common ways to produce methane-rich biogas, which has considerable potential to replace the fossil fuel used in multiple applications, such as vehicular transportation, internal combustion engines, cogeneration of heat and power systems and many other systems. Many companies are involved in the design and construction of anaerobic digesti...
