A consortium of anaerobic bacteria has been formulated and adopted to work at temp as low as 5 degree C. This is the component which acts as inoculums (seed material) to the FRP Bio Digester Tank and converts the organic waste in to methane and carbon dioxide. The anaerobic process inactivates the pathogens responsible for water borne diseases. Bio Digester serves as reaction vessel for bio-methanation and provides the anaerobic conditions and required temperature for the bacteria. The optimum temp is maintained by microbial heat, insulation of the reactor and solar heating at places wherever required.

Whole FRP Bio Digester Tank System have few parts such as mentioned below :
