Title
Real - time Control of Animal Wastewater Treatment System

Abstract
This research evaluated the usefulness of a newly invented real-time control technology in the treatment of piggery wastewater. The new unit treatment process composed of two reactors was operated under two different treatment strategies, real-time control and fixed-time control. Comparisons between the real-time control technology and the fixed-time strategy revealed that high treatment performance could always be obtained in the real-time control, despite variations in influent composition, but not in the fixed-time operation. The average removal efficiencies of pollutants were over 97% in the real-time control. However, the treatment efficiencies in the fixed-time control were relatively poor. Also, the obtained effluent quality was relatively constant in the real-time control, while the effluent quality in the fixed-time operation was seriously variable, depending on the influent characteristics. The results from this study indicate that the real-time control strategy has an ability to optimize simultaneously biological pollutant removal and energy consumption by terminating aeration when nutrient removal is complete.
