Integrated fault detection and isolation: Application to a winery's wastewater treatment plant

In this paper, an integrated object-oriented fuzzy logic fault detection an d isolation (FDI) module for a biological wastewater treatment process is p resented. The defined FDI strategy and the software implementation are deta iled. Using experimental results obtained with a one cubic meter fixed bed reactor for the anaerobic digestion of industrial wine distillery vinasses, examples of material and biological failures are presented together with t he corresponding fault signals generated by the FDI module.
