Sewer gas is a complex mixture of various gases and compounds, some of which are toxic to humans. The primary components of sewer gas include: hydrogen sulfide; methane; ammonia; carbon dioxide

sewage is nothing but waste water….which is obtained from domestic, industries etc…it consistes of some chemical and pathogenic bacteria that is harmful to d environment if its disposed in raw condition….that is why its also treated in almost a similar way like the drinking water….but involves much higher process….generally sewage is charcterized by its colour, content of suspended solids n most importantly based on amount of BOD(Biologically Oxygen Demand), COD(Chemical Oxygen ...

Sewer gas can contain methane and hydrogen sulfide, both highly flammable and potentially explosive substances. As such, ignition of the gas is possible with flame or sparks. The methane concentration in open sewers is lower (7 to 15 ppmv) than the closed drains (up to 300 ppmv) in samples collected 2 cm above the level of sewage.

Municipal wastewater treatment plants emit methane. Since methane is a potent greenhouse gas that contributes to climate change, the abatement of the emission is necessary to achieve a more sustainable urban water management. This requires thorough knowledge of the amount of methane that is emitted …

Sewage (containing dissolved methane) was sampled into freshly vacuumed BD vacutainer tubes using a hypodermic needle attached to a 5-mL plastic syringe that contained the sewage sample. The tubes were mixed overnight in a shaker to allow equilibration of gas and liquid phases.

Sewer gas is a generic name for the collection of gases and airborne agents that often accompany sewage and the natural processes and reactions associated with sewage processing and the decomposition of organic materials. The major components of sewer gas can include: nitrogen (N 2), hydrogen sulfide (H 2 S), carbon dioxide (CO 2), methane (CH 4

The wastewater treatment sector shows around 151 biogas and methane avoidance & utilization based projects registered under the CDM throughout the world. Average annual GHG emission reduction (Carbon Credits) are around 1,16,142 tCO 2 /year (Worth of Indian rupees 2,55,35,364 INR). Out of them, 11 CDM projects are from India.

Based on data from bench-scale experiments, a 1,000-TPD bioconversion facility could produce approximately 3-6 million cubic feet of methane per day based on a conservative value of 1.8 cubic feet of methane generated per pound of municipal solid waste and sewage sludge.
