INTRODUCTION TO BIOGAS

INTRODUCTION TO BIOGAS

Biogas technology is the transformation of organic materials through anaerobic digestion process under controlled conditions of temperature, pH, C/N ratio etc, to obtain a combustible gas, called biogas and a value-added fertilizer (sludge). Biogas usually contains from 45 to 70% Methane and from 30 to 45 % Carbon dioxide.

Anaerobic digestion is the degradation of organic wastes through microbial actions in the absence of oxygen to produce reducing gases (biogas) which mainly composed of methane, carbon dioxide and contains trace components which is hydrogen sulfide, acids and thiols. Degradation rate depends at large on feedstock type, hydraulic retention time (HRT) and process temperature.
