Description
This paper discusses the next generation of process control strategies for drinking water treatmentplants and illustrates why utilities should consider implementing them in the operation of theirplants in the near future to help stay abreast of treatment regulations and to control costs ofoperation. A review of advanced control techniques, equipment requirements, development ofprocess models using artificial neural networks (ANNs), and integration of models with plantcontrol systems is described. The paper also shows how utilities can begin implementing nextgeneration controls by leveraging their existing equipment and systems such as on-line analyzers,conventional controls, the SCADA (Supervisory Control and Data Acquisition) system, andhistorical plant performance data. The paper describes the concept of “plant-wide control”, aholistic approach at plant optimization that links and integrates various models (e.g. process,demands, production, and energy), overall cost of operation, final effluent water quality and othermanagement objectives into a constraint-based decision making system. Finally, two case studiesof next generation controls implemented in water plants managed by EPCOR Water Services(Edmonton, Alberta, Canada) are also presented. Includes 7 references, figures.
