Biogas Plant
A Biogas plant is a facility that converts organic waste materials, such as manure or food scraps, into Biogas. Biogas is a mixture of methane, carbon dioxide, and trace amounts of other gasses. This process of converting organic waste into biogas is called anaerobic digestion.
Biogas is an environmentally friendly and sustainable source of energy.Biogas plants can also help to reduce the amount of organic waste that ends up in landfills.

Biogas Plant Diagram- Fixed Dome Type
Fixed dome type biogas plant converts organic waste into useful products such as biogas and fertilizer.In this type of biogas plant Anaerobic digestion takes place in a sealed, airtight container. It has a fixed dome on top to collect the biogas with various outlets for the slurry and scum. The control panel and heating system are used to maintain optimal conditions for the anaerobic digestion process.
Description of Fixed Dome Type Biogas Plant Diagram labels is as follows
- Inlet
In Inlet organic waste is fed into the biogas plant. The waste can be in the form of kitchen scraps, animal manure, or agricultural waste.
- Digester tank
In Digester the anaerobic digestion process takes place. The digester is a sealed ,air tight container which is made of concrete or plastic. In Digester the organic waste is broken down by microorganisms in the absence of oxygen.
- Gas Holder/ Dome
Gas holder is a dome-shaped airtight structure that is placed on top of the digester tank. It is used to store the biogas that is produced during the anaerobic digestion process. The gas holder dome is designed to expand and contract as the biogas is produced and consumed. It also Prevents the biogas from escaping into atmosphere
- Gas outlet
Biogas which is produced during the anaerobic digestion process is collected in Gas Holder/ Dome and is released through the gas outlet. This biogas can be used as a fuel source for heating, cooking or generating electricity.
- Slurry outlet
The slurry which is produced during the anaerobic digestion process is collected in the digester tank and then it is released through the slurry outlet. Slurry is a type of Liquid fertilizer and can be used to enrich soil to improve plant growth.
- Scum outlet
Scum outlet is to remove any solid waste that accumulates on the surface of the digester tank. This solid waste can be composted or used as animal feed.
- Scraper
Scraper is used to remove the sludge from the bottom of the digester.
- Control panel
Control panel is used to monitor and control or adjust the various components like temperature, pH, and pressure in the digester tank. It Also monitors the biogas production and consumption.
Control panel is important for maintaining optimal conditions for the anaerobic digestion process.
- Stirrer /Mixer
The stirrer /Mixer is used to mix the organic waste in the digester tank . It ensures that the materials are evenly distributed throughout the digester which promotes efficient digestion and the microorganisms have access to all of the organic material.
- Heating system
The heating system is used to maintain the optimal temperature for the anaerobic digestion process. This can be done through the use of insulation or a heating element.
Biogas Plant Diagram- Floating Gas Holder type
Floating gas holder type biogas plant uses Anaerobic digestion to convert Feedstock into biogas. Biogas is stored in a floating gas holder in this type of Biogas plant.The biogas can be used for a variety of applications like electricity generation and heating.The Byproducts of the process are used as fertilizers.
Description of Floating gas holder type biogas plant Diagram labels is as follows-
- Inlet
Inlet from where organic material, such as food waste or agricultural waste, is added to the digester tank.
- Digester
Digester is a sealed tank where the Organic waste like slurry of cattle dung or agricultural waste is broken down by microorganisms in an anaerobic process. It produces biogas which is mainly composed of methane and carbon dioxide.
- Gas holder
The gas holder is a large, floating, airtight container that is placed on top of the digester. It is used to store the biogas produced by the digester of the biogas plant.
- Sludge
The solid material that is left over after the anaerobic digestion process is called ast the sludge. It can be used as a fertilizer.
- Effluent outlet
Effluent Outlet from where the remaining liquid from the digester is removed and can be used as a fertilizer.
- Control system
Control System monitors and regulates the temperature, pH, and other factors in the digester which optimize biogas production.
