Vedclass · Answer

(B) During the secondary treatment of sewage,the sediment of the activated sludge is pumped into large tanks called anaerobic sludge digesters.In these tanks,other kinds of bacteria,which grow anaerobically,digest the bacteria and the fungi in the sludge.During this digestion,bacteria produce a mixture of gases such as methane $(CH_4)$,hydrogen sulfide $(H_2S)$,and carbon dioxide $(CO_2)$.These gases form biogas and can be used as a source of energy.
