Anaerobic Digestion of Waste Organic Matter and Biogas Production

Abstract—We are interested in carrying out the process called anaerobic digestion of two different substrates: the biodegradable waste from landfill and sludge from the wastewater treatment plant by natural lagoon. The experiment is performed in a digester with a capacity one liter, sealed. To optimize the degradation of organic matter, we followed the evolution of the degradation of organic matter by measuring the CDO, the volume of biogas formed during the digestion, the temperature and the pH of the process. We found that the sludge off the wastewater treatment plant by natural lagoon is very rich in fermentable and biodegradable organic material than the proportion of fermentable material of the landfill. The biogas formed is flammable, so very rich in methane. The volume of biogas produced during the digestion of sludge is greater than 10 times compared with the digestion of organic matter in the landfill. Knowing beforehand that the volume of biogas produced is always a function of the residence time of digestion and the concentration of organic matter.

Index Terms—Methanogenesis, organic matter, anaerobic digestion, biogas, sludge.
