The main sources of methane detected by these authors were related to the sludge line units where anaerobic digestion is carried out: the primary sludge thickener, the centrifuge, the exhaust gas of the cogeneration plant, the buffer tank for the digested sludge, and the storage tank for the dewatered sludge.

By setting up mass balances over the different unit processes, it could be established that three quarters of the total methane emission originated from the anaerobic digestion of primary and secondary sludge. This amount exceeded the carbon dioxide emission that was avoided by utilizing the biogas.

Methane production by anaerobic digestion of wastewater and solid wastes T.Z.D. de Mes, A.J.M. Stams, J.H. Reith and G. Zeeman1 4 4.1 Introduction Anaerobic conversion of organic materials and pollutants is an established technology for envi-ronmental protection through the treatment of wastes and wastewater. The end product is biogas

Methane is emitted during the production and transport of coal, natural gas and oil. Emissions also are produced by the decay of organic matter in municipal solid waste landfills, some livestock manure storage systems, and certain agro-industrial and municipal wastewater treatment systems. Methane offers a unique opportunity

1. Introduction. During wastewater treatment, the greenhouse gases carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) can be emitted to the atmosphere (Hofman et al., 2011).Carbon dioxide is produced indirectly as a result of fossil fuel combustion to generate the energy required for the operation of the wastewater treatment plant, or it is produced directly during the respiration ...

Methane is produced during the anaerobic decomposition of organic material in livestock manure management systems. Liquid manure management systems, such as lagoons and holding tanks, can cause significant methane production and these systems are commonly used at larger swine and dairy operations.

Wastewater from domestic (municipal sewage) and industrial sources are treated in municipal sewage treatment facilities and private effluent treatment plants (ETPs). If the wastewater contains loads of organic constituents (with high Chemical Oxygen Demand- COD) then it is treated anaerobically. These treatment processes produce methane which is one of the potent Green House Gas.

Methane is generated from wastewater treatment and landfills through the anerobic decomposition of organic material.

Highlights Methane emission from a municipal WWTP was quantified in total and per unit process. The anaerobic digestion related unit processes caused three quarters of the emission. Dissolved methane was sampled with a method based on salting-out of dissolved gases. Better handling of ventilation air from sludge facilities can decrease methane emission. Dissolved methane was aerobically ...
