- W187620497 abstract "In the Laboratory of Water and Environmental Engineering at Tampere University of Technology there has been an ongoing project to study automation in the control of the activated sludge process (ASP). As part of the project, an expert system was developed for the operation and control of the ASP and the practical adaptation of the system was studied. The study began with the monitoring of a pilot-scale reactor of 250 1 capacity and its control using conventional control loops (PID) for DO and flow rates. The reactor was fed with synthetic wastewater (wheat flour and milk powder mixture consisting of approximately 600 mg of COD/1). Besides classical DO, MLSS, pH and flow rates, the three main parameters which were measured for use in the expert system were sludge volume index (SVI), sludge age (SA) and oxygen uptake rate (OUR). On the basis of these measurements, plus a certain amount of visual inspections and microscope studies, research started with the creation of rules for the operation and control of the pilot system. The expert system is continuously being tested, not only in the pilot system, but also in a full scale treatment plant in the city of Tampere, where the incoming load is normally about 20000 cubic metres per day and the incoming COD about 200- 300 mg/1." @default.
