Abstract

A report is presented on a collaborative study of dynamic modelling and control of the activated sludge process in wastewater treatment. The report divides into four major parts, the first of which presents and discusses the time-series of field data from the Norwich Sewage Works in England. The second part of the paper is concerned with the identification of a model for nitrification in the activated sludge process from the given field data; the technique used for this purpose is an extended Kalman filtering algorithm. A third section deals with the construction of a detailed simulation model which has been used for control system design and evaluation. The final major part of the report introduces some basic ideas of fuzzy control, suggests why conventional control schemes may be of limited value in wastewater treatment systems, and proceeds to define a fuzzy controller developed from the empirical experience of the Norwich Treatment Plant manager. The paper also offers some thoughts on future perspectives for the study and for the use of mathematical models as aids to the operational control of wastewater treatment.
