Modelado y simulación de una planta de tratamiento de aguas residuales empleando modelos ASM

Abstract

Water pollution is one of the biggest problems in the environment. The treatment of wastewater, resulting from human activities, is essential to maintain a healthy balance in ecosystems. For this research, the ASM1 model was applied in WTP of the EMRAQ-EP, with the help of GPS-X software. The physical, chemical and biological characterization of the wastewater generated by the work of the Metropolitan Camal of Quito was performed. Based on the parameters set in the ASM1 activated sludge model, the input data was obtained to generate a model close to reality to perform the simulation, achieving the validation of the research. Based on pre-sampling, two campaigns were concluded for the characterization of the influent and the model's fractions were determined, for which characterization protocols were applied. The entries in the GPS-X software were determined from the results obtained in the campaign and the calculations made later. The Influent Advisor program was used to determine initial conditions and model the bioreactor. The simulations were performed in a dynamic state, with the fractions calculated and calibrated, to estimate the behavior of the PTAR. R2 was calculated to determine the validity of the results obtained.
