In this paper. development of a cODlIol system for the activated sludge plant of Quest International Naarden BV is presented. The control system is based on on-line measurements of the actual respiration rate in the carrousel. From model sim ulations we conclude that overloading can be prevented by manipulating the wastewater flow rate. Energy can be saved. A day/night control of the aerators will result in energy cost savings between 11 and 21 %.
