The sequence of events occurring in a biogas plant are as follows: (i) The biogas plant tank is fed with a slurry of dung. (ii) A floating cover is placed over the slurry, which keeps on rising as the gas is produced in the tank due to the microbial activity. , (iii) Methanogens like Methanobacterium grows anaerobically on cellulosic plant material in cow dung to produce large amount of methane, C02 and H2. (iv) The plant has an outlet, which is connected by a pipe to supply biogas in nearby houses. (v) The spent slurry is removed through another outlet and used as biofertilisers. A-Sludge tank B-Gas holder C-Dung water
