Question

Explain the biogas plants with a labeled diagram.

Answer 1

Hint: Production of fossil fuel from plant and animal waste by the means of geological process under aerobic conditions.

Complete answer:
Biogas is a mixture of gases produced by the breakdown of organic matter in the absence of oxygen. It mainly consists of carbon dioxide and methane.
Biogas can be produced from raw materials like agricultural waste, manure, plant material, etc. It is a renewable source of energy, also known as “Gobar Gas”.

Working of Biogas plant-
1) Biogas is made in a digester which is a tank filled with bacteria that eat organic waste and give flammable gas (biogas).
2) The bacteria in the tank should be taken care of well and proper food is to be given.
3) The bacteria convert organic matter into methane gas through anaerobic respiration.
4) The operator of the biogas system feeds the digester with household by-products like kitchen waste, manure, etc.
5) The methane gas produced can be used for cooking, lighting, etc.
6) The waste which is fully digested will form an organic fertilizer.
7) Its main part consists of:
a. Mixing tank
b. Inlet chamber
c. Digester
d. Outlet chamber
e. Overflow tank
8) This is also called anaerobic digester, biodigester, or a bioreactor.

Note: Bioenergy is renewable energy made from biological sources. It is a synonym to biofuel, which is a fuel derived from biological sources. It was used first in Assyria to heat water baths but was first recorded in modern times by Jan Baptita Helmont.
