“…12,14,15 Therefore, WWTPs operators prefer to prevent from damaging the microbial consortium, which is not adapted to the different substrates, what might interrupt or even stop the process. 16,17 To face this limitation, Garcia-Gen et al (2015) 18 developed a robust control system based on linear programming 19 with control principles. Despite this system was developed for an hybrid Upflow Anaerobic Sludge Blanket-Anaerobic Filter reactor to treat liquid wastes, it can be useful for other reactor configurations and solid co-substrates.…”
