| الوصف: | 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. |
