Improving the amount of biogas production from cow manure by adding chicken manure via anaerobic digestion

Abstract EN

This research studies the possibility of producing biogas from a mixture of cow and Chicken manure with different solid materials concentration ratios with the constant temperature at (35oC), a constant ratio of water (1:1.5) and the constant pH 7 with a retention time of 10 days.

In addition, the solid materials concentration ratio is (100% Cow manure, 90% Cow with 10% Chicken manure, 80% Cow with 20% Chicken manure, and 70% Cow with 30% Chicken manure).

The results of the accumulated biogas yield at the end of the digestion for CM70%, CM80%, CM90%, and CM100%.

was 460 ml, 385 ml, 315 ml, and 205 ml respectively.
