Detecting Anomalous Air Flow-ammonia Load Ratios, Using Gaussian Process Regression
2015 (English)In: Proc. 9th IWA Symposium on Systems Analysis and Integrated Assessment, 2015Conference paper, Presentation (Other academic)
In this paper we propose a method to detect abnormal air flow-ammonia load ratios in active sludge basins. The purpose is to detect faulty sensors and process disturbances affecting the air flow-ammonia load ratio. The method is based on Gaussian process regression, and is evaluated on plant data. Results indicate that drift in an ammonia on-line sensor, over flow during storm events and changed sludge properties can be detected by the proposed method.
