Aeration control - a review
Författare
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.
