Cyclic aeration has been practiced at several locations for nitrogen removal in activated sludge plants. Little data is available in the literature, however, to demonstrate the performance of actual systems compared to simulations based on process theory. In the current paper, the authors present data from field measurements of process parameters and compare these data to results derived from a computer simulation of the process. A series of control options were evaluated, using timers, oxidation-reduction potential (ORP), and dissolved oxygen (DO). It is concluded that a combined control strategy using all three—timers, ORP and DO—best satisfies the goals of reduced energy consumption and enhanced control of effluent quality.
