Scaling a Biodigester Ascendant Flow for Biogas Production via Sewer and Solid Waste

Abstract

The residues originating from sewer pipes and urbane garbage need treatment before being discarded in the environment to avoid the contamination of grounds, water sheets and dissemination of diseases. Besides the bad smell and of being forts contaminants, these residues are still collaborators of the greenhouse effect due to the composition of the gases that comes from his decomposition. The high methane concentration in the composition of these gases favors the production of biogas, what can be converted in electric or thermal energy. The objective of this study is to conduct a case study of the implementation of a biodigester in a residential condominium, aiming for the treatment of the residues and use of a produced biogas, minimizing damage to the environment.
