Aeration control - a review

På svenska

Author

Summary, in English

This review covers automatic control of continuous aeration systems in municipal wastewater

treatment plants. The review focuses on published research in the 21st century and describes

research into various methods to decide and control the dissolved oxygen (DO) concentration and to

control the aerobic volume with special focus on plants with nitrogen removal. Important aspects of

control system implementation and success are discussed, together with a critical review of

published research on the topic. With respect to DO control and determination, the strategies used

for control span from modifications and developments of conventional control methods which have

been explored since the 1970s, to advanced control such as model-based predictive and optimal

controllers. The review is supplemented with a summary of comparisons between control strategies

evaluated in full-scale, pilot-scale and in simulations.
