This paper discusses the next generation of process control strategies for drinking water treatment
plants and illustrates why utilities should consider implementing them in the operation of their
plants in the near future to help stay abreast of treatment regulations and to control costs of
operation. A review of advanced control techniques, equipment requirements, development of
process models using artificial neural networks (ANNs), and integration of models with plant
control systems is described. The paper also shows how utilities can begin implementing next
generation controls by leveraging their existing equipment and systems such as on-line analyzers,
conventional controls, the SCADA (Supervisory Control and Data Acquisition) system, and
historical plant performance data. The paper describes the concept of "plant-wide control", a
holistic 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 other
management objectives into a constraint-based decision making system. Finally, two case studies
of next generation controls implemented in water plants managed by EPCOR Water Services
(Edmonton, Alberta, Canada) are also presented. Includes 7 references, figures.
