Question:
Composition of biogas produced during sewage treatment is
Composition of biogas produced during sewage treatment is
Show Hint
Biogas = CH$_4$ + CO$_2$ + H$_2$S — no oxygen or nitrogen involved in anaerobic generation.

methane, oxygen, hydrogen sulphide.
- hydrogen sulphide, methane, oxygen.
- hydrogen sulphide, nitrogen, methane.
- methane, hydrogen sulphide, carbondioxide.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Biogas primarily consists of methane (CH$_4$), along with carbon dioxide (CO$_2$) and traces of hydrogen sulphide (H$_2$S). Oxygen and nitrogen are not typical components of biogas generated via anaerobic digestion in sewage treatment.
