BIO GAS
Biogas generated from DEWATS
Biogas is a product of the anaerobic d i g e s t i o n or f e r mentation of biodegradable materials such as manure, sewage. The methane in biogas gives it the ability to be used as a fuel.


The combustion of methane in biogas releases energy and can be used as a lowcost fuel for cooking and lighting. However if biogas being released is minimal or if it is not likely to be used, it should be released in the air by safe ventilation .


 
 
Gas Collection and Storage


The biogas is produced within wastewater and sludge, from where it rises in bubbles to the surface. The gasmust be collected above the surface and stored until it is ready for use. Gas bubbles cause turbulence which leads to explosive release of gas in a chain reaction. As a result of this, gas production fluctuates by plus/ minus 25 % from one day to the other. The volume of gas storage must provide for this fluctuation.

There are several models of bio gas plant available in India:
1. Floating Dome
a. KVIC
b. Pragati
c. Ganesh

2. FixedDome
a. JanataBiogas Plant
b. Deenbandhu Biogas plant
c. Ferrocement biogas plant
