Abstract:
Digesters are anaerobic bioreactors generally made up of closed tanks, airtight and thermally insulated from the outside in which different microorganisms chemically and biologically degrade organic waste and effluents to produce biogas. This research led to the realization and testing of a digester from a metal drum at Julius Nyéréré University in Kankan. The digester was loaded on January 10, 2020 with cow dung diluted with water. After 30 days of digestion, the produced biogas was tested for fuel by boiling water and roasting the eggs. During the digestion process, the variation in temperature and pressure revealed that it is necessary to thermally insulate the tank (digester) or to place it in an isothermal chamber favorable to the development of metagenesis bacteria. Monitoring of the change in pH showed three phases (acidification, alkanization and stabilization).
