Discuss the steps involve in design of biogas plant with suitable parameters and working diagram.
Answers
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.
Explanation:
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.
