The rate of reduction in of substrate sludge was estimated at
82.44% and the substrate of the landfill is 87.3%. The biogas
produced in the two substrates is flammable, especially since
the second day of the digestion of the substrate sludge.
Substrate for the landfill, the onset of methanogenesis is
detected on day 9. Phase methanogenesis was not inhibited
the pH decreased to 6.68 for the substrate of the discharge for
the substrate and 6.76 for sludge off waste water treatment.
This slight decrease in pH shows that the substrate used for
the two tests is readily biodegradable. Digestion temperature
remains between 35°C and 37°C. The anaerobic digestion
process offers the possibility of combining the treatment of
waste and the production of renewable energy is biogas rich in
methane CH4. The volume of biogas produced during the
digestion of sludge of waste water ( 5 000 mL)) is greater than
10 times compared with the digestion of organic matter in the
landfill waste (500 mL)in the time of digestion 30 days.
Methanogenesis and final phase is the specific step of
