    Abstract

    The use of sequencing batch bioreactors (SBR) for treating polluted wastewater is environmentally important. But the standard operation of SBRs is far from optimal when treating toxicants, because of the inhibition phenomena. The main technical problem is the lack of practical pollutant sensors. In this work an event-driven time optimal control (ED-TOC) is proposed to circumvent these problems. By measuring the dissolved oxygen and estimating some reaction rate events the ED-TOC maintains the pollutant concentration at optimal levels, and provides a robust, economical and an almost time-optimal operation mode.
