Propuesta metodológica para dimensionar un reactor anaerobio apto a bajas temperatura en el tratamiento del agua residual doméstica en Colombia

Abstract

The present document seeks to evaluate the implementation of anaerobic reactors in places whose altitude is equal to or greater than 2000m above sea level and the Ambient temperature of the place does not exceed 20 ° C in Colombia. For this the author mentioned the theoretical elements, under an extensive bibliographic review within the national and international context, describing and comparing the physicochemical and biological characteristics of various anaerobic reactors of the upflow type (UASB), plug flow (PRF), and completely mixed. (CSTR) among other less common anaerobic units. The applied methodology is deductive, to propose a methodology for design a type of anaerobic reactor capable of taking advantage of highly energetic materials such as biomass and biogas present in domestic wastewater. Proposing in this way an alternative to the optimization of resources in the existing domestic wastewater treatment systems in Colombia, dependent on the elimination of contaminants, mainly colloids (pathogenic organisms) and organic matter present and integrated in such a way to the generation of biomass-type renewable energy, through the bioconversion of methane and volatile acids. Which considers anaerobic reactors within an advanced group in the treatment of domestic wastewater, since it reduces atmospheric emissions and presents a good percentage of pollutant removal in effluents with low oxygen saturation, favorable conditions for this case study.
