1. 1. Fault detection in water resource recovery facilities

   Författare :Oscar Samuelsson; Bengt Carlsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Reliable sensor values are important for resource-efficient control and operations of wastewater treatment processes. Automatic fault detection methods are necessary to monitor the increasing amount of data produced in any modern water resource recovery facility (WRRF). LÄS MER

3. 2. Sensor Fault Detection and Process Monitoring in Water Resource Recovery Facilities

   Författare :Oscar Samuelsson; Bengt Carlsson; Elling W. Jacobsen; Uppsala universitet; []
   Nyckelord :Aeration efficiency; anomaly detection; ammonium feedback control; change detection; covariance matrix; diffuser fouling; experimental design; Gaussian process regression; novelty detection; wastewater treatment;

   Sammanfattning : Water resource recovery facilities (WRRFs) operate 24/7 to reduce the environmental impact from wastewater on receiving waters. Inaccurate measurements hinder the improvement of operations, limits the performance of automatic control, and deteriorate data quality for decision support and other purposes. LÄS MER
