Modelling and dynamical analysis of unitank biological wastewater

Abstract

By applying modern model based control theory to biotechnological systems such as wastewater treatment plants important process improvements can be expected. Mathematical (low complexity) models, useful for dynamical optimization of systems and for the design of on-line model based controllers have been developed. A new technique, based on equilibrium lines in the state space domain, is introduced to analyze the dynamic behavior of such systems. The use of sensitivity studies as a tool to discriminate between different model structures is clearly illustrated

Keywords:

• cyclically operated wastewater treatment systems
• sensitivity analysis
• state space analysis
