Bio Gas Plant

Biogas Plant:

A biogas plant has a digester in which the biomass is decomposed, a mixing tank for mixing the biomass with water, an outflow tank and a means of collecting gas. The biomass, e.g., cattle dung, is mixed with water in the mixing tank to form slurry. The slurry from this tank flows into the digester, which is a sealed chamber. The biomass decomposes here and expands, and the gas produced presses down the slurry. This causes the spent slurry to overflow into the outflow tank. The spent slurry is used as manure. The upper part of the digester has an outlet for gas.
