Question

In anaerobic sludge digestion during secondary treatment of sewage, biogas is produced, which is a mixture of (A) methane H2S and H2S  (B) methane and CO2  (C) methane, H2S,CO2 and CO (D) methane, H2S,CO2 , CO and ethane

Tardigrade Admin · Accepted Answer

Archaebacteria and methanogens are evolved in production of biogas or gobar gas. Some other bacteria involved in degradation process are Bacillus clostridium, Bacterium, etc. Biogas is produced during second treatment of sewage by anaerobic degradation of sludge by microbe, which is a mixture of CH 4(50-70 %), CO 2 (25-35 %) H 2 (1-5 %) N 2 (2-7 %) and O 2 (0.0-1 %) and rarely H 2 S.
