FROM THE PREFACE Dynamic modeling, computer simulation, and modern control systems are valuable tools for use in both the design and operation of dynamic systems. From the "tools" point of view, this book is designed to show practicing engineers how to develop models capable of describing dynamic behavior and how to "solve" these models using computer simulation. The basic principles of process control are also presented so that the effects of different control systems on dynamic behavior can be established by computer simulation.

Instrumentation, Control and Automation of Water and Wastewater Treatment and Transport Systems documents the proceedings of the 5th IAWPRC Workshop held in Yokohama and Kyoto, Japan, 26 July-3 August 1990. The papers presented at this Workshop have emphasized the following aspects: • new sensor technology based on developments in electrochemistry, fiber optics, and electro-optics; • research into materials such as those needed to produce membranes of the required selectivity, for immobilization of reactive species, and for addition of reagents and standards; • the use of inferential measurements coupled with expert system technology; • the ever-increasing power of microprocessors and the continuing reduction in their unit costs; • better communications capability; • improved mathematical modeling; • an increased awareness of the improved management that results from the timely availability of relevant data to the appropriate levels in the management hierarchy. This book, together with the proceedings of previous workshops, provides what is probably the most comprehensive account of the state of the art and recent developments in instrumentation, control, and automation as applied to the water and water-using industries, and as such will be invaluable to the practitioner, the researcher, and the student community.
