Two-Level Multivariable Control System of Dissolved Oxygen Tracking and Aeration System for Activated Sludge Processes

Abstrakt

The problem of tracking dissolved oxygen is one of the most complex and fundamental issues related to biological processes. The dissolved oxygen level in aerobic tanks has significant influence on behaviour and activity of microorganism inhabiting the plant. Aerated tanks are supplied with air from an aeration system (blowers, pipes, throttling valves, diffusers). It is a complex dynamic system governed by nonlinear hybrid dynamics. Control of the aeration system is also very difficult in terms of control the dissolved oxygen. This paper extends newly developed two-level multivariable control system for tracking dissolved oxygen and control an aeration system. A nonlinear model predictive control algorithm was applied to design controllers for each level. This overall hierarchical control system was validated by simulation based on real data records provided by a wastewater treatment plant located in Kartuzy, Northern Poland. The impact of control system parameters and disturbances were also investigated.
