Employment of a Nonlinear Adaptive Control System for Improved Control of Dissolved Oxygen in Sequencing Batch Reactor

A proper control in a complex system, such as Wastewater Treatment Plant (WWTP) with each year is becoming increasingly important. High quality control can minimize an environmental impact as well as reduce operational costs of the WWTP. One of the core issues is providing adequate dissolved oxygen (DO) concetration for microorganisms used in a treatment process. An aeration process of the wastewater realised by an system consisting of blowers, pipelines and dif-fusers generates a large proportion of the costs. This paper presents an employ-ment of a nonlinear adaptive control algorithm Extremum Seeking Control for improved control of DO. For the control design process, models of the aeration system and the biological processes are implemented. The control results based on performed simulation tests are presented.
