DRDO developed Biodigester technology is environmental friendly, maintenance free and efficient without depending on conventional energy sources. The effluent is odorless and gets rid-off most of the pathogens.


The biodigester technology has two components:
-anaerobic microbial consortium
-and specially designed fermentation tank.

The microbial consortium has been made by acclimatization, enrichment and bioaugmentation with the coldactive bacteria collected from Antarctica and low temperature areas. It is composed of four clusters of bacteria belonging to hydrolytic, acidogenic, acetogenic and methenogenic groups with high efficiency of biodegradation.

Fermentation tank is made of metal/ FRP and has the provision of immobilizing the bacteria in large numbers.


Special Features

-Anaerobic microbial inoculum

-Specially designed tank for efficient biodegradation

-Cold tolerant microbial consortium
