Anaerobic Co-digestion of Giant Reed for Biogas Recovery

2. Production of Biogas by Anaerobic Digestion

Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands, and in the digestive tract of ruminants. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an an...

Pretreatment Methods in Anaerobic Digestion for Biogas Generation: A Review

Biogas energy has got importance in the field of energy engineering because of its attractive features. Biogas is produced from different types of waste materials by the process of Anaerobic Digestion. This paper gives the insight of Anaerobic Digestion process and different pretreatment methods used in various experimental research works. Flower waste is also a potential source of biogas energ...

Biogas production by anaerobic co-digestion of cattle slurry and cheese whey.

Biogas yield of mixtures of cattle slurry and cheese whey, rates of production of methane, removal efficiencies of chemical oxygen demand (COD) and biological oxygen demand (BOD) were investigated at 35 °C. Stable biogas production of 621 l/kg volatile solids at a hydraulic retention time of 42 days in a mixture containing 50% slurry and whey was obtained. The concentration of methane in the bi...

[Article] Biogas production by anaerobic co-digestion of cattle slurry and cheese whey

Biogas yield of mixtures of cattle slurry and cheese whey, rates of production of methane, removal efficiencies of chemical oxygen demand (COD) and biological oxygen demand (BOD) from the mixtures were investigated at 35°C. Four feed regimens (by volume) were studied. Stable biogas production of 621 l/kg Volatile Solids at an Hydraulic Retention Time of 42 days in a mixture containing 50% slurr...
