Application of the roediger mathematical model for the prediction of performance in the anaerobic digestion of coffee wastewater

Abstract

The objective of the research that gave rise to this article was to establish an objective measurement mechanism for the prediction of methane yield in the anaerobic digestion of coffee wastewater. From a quantitative approach, the Roediger model, solution method, error analysis, optimization criteria and comparison between experimental and predicted values are used, arriving at the following conclusions: The adjustment methods applied in the present investigation generate similar results. each other, which are related to the experimental performances of the anaerobic digestion of coffee wastewater. It can be seen graphically that the isotherms follow the same trend and it can be corroborated through the analysis of variance (ANOVA) that the significance between the average of the statisticians used to evaluate the prediction of the Roediger model is relatively high. Therefore, the Roediger model constitutes a mathematical tool that can predict the methane yield of coffee wastewater in a statistically significant range, under the experimental conditions and requirements detailed in this work. Through the ANOVA analysis of variance, it was shown that the variables that make up the Roediger model, such as the maximum methane yield and kinetic constant, do not have a statistically significant relationship, since the probability value is greater than 0.05. The present study contributes to the scientific community and establishes a basis to carry out studies that evaluate other mathematical models with variables that characterize the development, inhibition and productivity of this biochemical process.
