Estudio cinético de la digestión anaerobia de mezclas de desechos de fruta

摘要

To design, build and operate biogas plants in optimal conditions it is required to start a kinetic study of the anaerobic digestion. This thesis project involves an in depth study of the degradation rate of fruit waste with respect to a series of parameters such as the concentration of organic material expressed as the chemical oxygen demand, temperature, residence time and pH. The degradation rate is expressed as the production of biogas under different scenarios. A nitrogen-rich fertilizer can be obtained from the anaerobic digestion of fruit waste and cow manure, which is used as an organic fertilizer to deliver a better crop production. Biogas, a methane-rich gas is also produced in this process. Therefore the anaerobic digestion can be used as an alternate energy source and represent a partial solution to the lack of fuel.
