• B. Biogas plant does not have an outlet
• C. The slurry is removed and may be used as a fertiliser
• D. The concrete tank is 10-15 feet deep

Answer 1

Answer:

B. Biogas plant does not have an outlet

• The biogas plant has a 10-15 feet deep concrete tank.

• A floating cover is placed over slurry which keeps on rising as the gas is produced in the tank due to the microbial activity.

• The biogas plant has an outlet, which is connected to a pipe to supply biogas to nearby houses.

• Also, the slurry can be removed and may be used as a fertiliser.
