| description | The Membrane Bioreactor (MBR) has recently emerged as an important technology product for the treatment of wastewater containing estrogens and contaminants and is capable of transforming a residual water in a high quality effluent. Because of the recalcitrant nature of both natural and synthetic estrogens, one of the parameters that has been determined as influential to the removal of these substances is the Solids Retention Time (SRT), as this allows more time spent in the biomass in the reactor. The influence of the SRT in estrogen removal was simulated in the MATLAB Fuzzy Logic Toolbox using fuzzy control. For this purpose, the values measured or obtained by experts in laboratory scale experiments were fuzzified, and on the basis of previously designed inference rules, the inference process was performed, and finally the output is again desfuzzified for crisp value. The designed fuzzy control system produced very good results, with very small percentages of error for most cases, except for the removal of EE2 in the reactor with long SRT. The performance of the simulation allows us to conclude that the Fuzzy Logic Toolbox is a good tool to get close to the results obtained by an actual experimental system. |

El Biorreactor de Membranas (BRM) emergió recientemente como un importante producto tecnológico para el tratamiento de aguas residuales que contienen contaminantes de tipo estrogénico, obteniendo efluentes de alta calidad. Debido a la naturaleza recalcitrante de los estrógenos, uno de los parámetros que se ha determinado como influyente en la remoción de estas sustancias es el Tiempo de Retención de Sólidos (TRS), ya que este permite un mayor tiempo de permanencia de la biomasa en el reactor. Se simuló en el Fuzzy Logic Toolbox de MATLAB la influencia del TRS en la remoción de estrógenos mediante control borroso; se borrosificaron los valores obtenidos por expertos en experimentos a escala de laboratorio, y sobre la base de las reglas de inferencia previamente diseñadas se realizó el proceso de inferencia borrosa, y finalmente se desborrosificó la salida para obtener de nuevo un valor nítido. El sistema de control borroso diseñado produjo muy buenos resultados, con porcentajes de error muy pequeños para la mayoría de los casos, excepto para la remoción de EE2 en el reactor con largo TRS. La simulación permite concluir que el Fuzzy Logic Toolbox es una buena herramienta para obtener resultados cercanos a los obtenidos mediante un sistema experimental real.
