摘要：

This report deals with the detection and diagnosis of faults when they develop in different parts of a wastewater plant, situated in Manresa, Spain. When a fault occurs, estimates of the parameters in a non-linear mathematical model of the plant change. In this paper, three methods for detecting and tracking changes in different physical parameters are compared and assessed by using real data from experiments on the wastewater treatment plant.
