Improve Biogas Production By Using Bacteria

Biogas is one of the sources of renewable energy because it works to get rid of animal and agricultural waste and turn it into an important source of energy, especially in remote areas. To produce this gas, laboratory units of 2 liter capacity were created from a process called anaerobic digestion. Also, two models (outside and inside the farms) were used to produce the biogas for each of cow manure and chicken droppings at 35, 45, and 55 °C temperatures. The amount of biogas produced from the animal waste collected from outside the farms is larger than the amount of gas produced from the animal waste collected from inside the farms. Also, the biogas production of the cow manure model for 60 days was 325 liter/ kg at 55 °C, 215 liter at 45 °C, and 189.5 liter / kg at 35 °C. While the biogas production of the chicken droppings model for 60 days was 465.5 liter / kg at 55 °C, 370 kg / liter at 45 °C, and 225 liter / kg at 35 °C. The results also showed that the analysis of this gas produced from the anaerobic digestion of cow manure and chicken pellets was highest at 55 °C and for 60 days. The percentage of methane gas which accounted was 79% for the biogas produced from treated cow manure at 55 °C, but it was 67% for the biogas produced from the treated chicken droppings. While the stabilization stage of the aggregates and the percentage of gas methane is more than 90% at the end of the operating phase.
