In the airtight
container, animal manure will change into
digestive fluid and during that process
biogas will be generated. There are three
steps in this process. First step is the
decomposition (hydrolysis) of organic matter
contained in manure. Second step is synthesis
of acetic acid out of decomposed matter.
The final step is methane gas formation
from acetic acid through the action of microorganism
called methanogen.
Biogas contains carbon dioxide and a slight
amount of hydrosulfide as well as methane
gas. Hydrosulfide is an obstacle for utilization
of biogas, because it is corrosive. After
desulfurised through biological method,
biogas can be used for power generation. |
