Abstract

The use of sequencing batch bioreactors (SBRs) for treating polluted waste water is environmentally important. The standard batch operation mode of SBRs is far from optimal for treating toxicants. Besides, if a toxicant peak concentration is fed to the SBR, this inhibits or even kills it. The main technical problem is the lack of practical pollutant sensors. In this talk, an event-driven control is presented, that circumvents this problem by measuring the dissolved oxygen and estimating some reaction rate events. Moreover, it maintains the pollutant concentration at optimal levels, and provides a robust, economical and sub-optimal operation mode for SBRs. Experimental results at a labor reactor demonstrate the advantadges of the proposed control.

Biographical Information

Jaime Moreno received his PhD degree in Automatic Control from the Universität der Bundeswehr-Hamburg, in 1995, and the Diplom-Degree from the Universität zu Karlsruhe, in 1990. Since 1995 is Professor at the Automation and Control Department at the Institute of Engineering, National University of Mexico (UNAM) in Mexico City. His current research interests include robust and non-linear control with application to biochemical processes (wastewater treatment processes), and design of nonlinear observers for nonlinear systems.
