Different control strategies are compared, in regard to issues associated to biomass inhibition when treating toxic wastewater, to operate sequencing batch bioreactors. in particular the problem of time optimal operation and also the problem of handling sudden unknown toxicant peak concentrations are addressed. Because of the application characteristics it is not feasible, nowadays, to measure all of the important variables, thus little information is available online for controlling the process. One of the alternatives presented, the Event-Driven Time Optimal Control, offers to solve all problems, using only the practically available variables, even if uncertainties are present in the mathematical model of the bioreactor.
