Abstract

The diagnosis of qualitative variables in certain types of batch processes requires time to measure the variables and obtain the final result of the released product. With principal component analysis (PCA) any abnormal behavior of the process can be detected. This study proposes a method that uses contribution plots as fault signatures (FS) on the different stages and variables of the process to diagnose the quality variables from the released product. Therefore, in a product resulting from the abnormal behavior of a process the qualitative variables that need to be measured could be obtained through the quantitative variables of the process by classifying the FS with a knowledge model from a fault signature database (FSD) extracted with a classification algorithm. The method is tested in a biological nutrient removal (BNR) sequencing batch reactor (SBR) for wastewater treatment to diagnose qualitative variables of the process: ammonium (NH+4 ), nitrates (NO−2 or NO−3) and phosphate (PO3−4).
