Methodology Statement of Bio Gas Plant
BARC has developed NISARGRUNA Bio Gas Technology for the treatment of organic waste. The bio gas plant works on principle of Biomethanation where thermophilic microorganisms treat the organic waste to generate methane gas and organic manure.
The biogas plant consists of following units.
- Mixer / Crusher: Segregated organic waste (frees of plastic, paper, metal, clothe and glass) is charged into mixer along with water. It is crushed here to obtain uniform slurry.
- Primary Digester: The organic waste slurry mixed with hot water is charged into primary digester. The primary digester serves mainly as hydrolysis cum acidification tank for treatment of suspended solids. Compressed air is used which helps in increasing aeration. The primary digester is designed in such a way that after the system reaches equilibrium in initial 4-5 days the fresh slurry entering the tank will displace the equal amount of digested matter from top into main digester tank.
- Main Digester: Main digester serves as methane fermentation tank and BOD reduction takes place here. The bio gas is collected in a dome (gas holder). It fits like a cap on the mouth of digester and it is submerged in the water. The bio gas produced from slurry is collected in dome and being lighter than air it rises upward. 1” / 2 “ MS /GI piping is provided to transfer the biogas.
- Sludge drying bed: The treated overflow of main digester is connected to sludge drying beds or manure pits. Natural drying of slurry results into high quality organic manure.

Salient features of BARC NISARGRUNA TECHNOLOGY
- Technology developed by BARC
- Two stage Aerobic and Anaerobic process
- Air Circulation in Primary Digester.
- Methane Recirculation in Secondary Digester.
- Use of hot water and air Compressor.
- Easy to operate, no complex mechanism.
Advantages of Bio gas Plant
- A very convenient way to treat biodegradable waste.
- Clean, hygienic and pollution free environment.
- Airtight top covers of the system hence no odor or smell.
- No flies, mosquitoes or rats and rodents problem.
- Electric consumption and water consumption are very low.
- Saving on transportation of waste.
- Smoke free fuel can be used for cooking, in boilers or for electricity generation.
- Compact size and Organic manure as a by product
Gas Utilization System
- Gas can be used directly for cooking by installing special type of burners.
- For Hot Water Generation.
- Gas can be supplied to bio generator / micro turbine and Electricity can be generated to be used for street lights at surrounding areas. Diesel not required.
- Gas can be fed to boiler and steam can be generated. Dual burners can be developed which can run on gas and FO/ LDO.
