Instrumentation, control and automation (ICA) in wastewater treatment systems is now an established and recognised area of technology in the profession. There are obvious incentives for ICA, not the least from an economic point of view. Plants are also becoming increasingly complex which necessitates automation and control. Instrumentation, Control and Automation in Wastewater Systems summarizes the state-of-the-art of ICA and its application in wastewater treatment systems and focuses on how leading-edge technology is used for better operation. The book is written for: The practising process engineer and the operator, who wishes to get an updated picture of what is possible to implement in terms of ICA; The process designer, who needs to consider the couplings between design and operation; The researcher or the student, who wishes to get the latest technological overview of an increasingly complex field. There is a clear aim to present a practical ICA approach, based on a technical and economic platform. The economic benefit of different control and operation possibilities is quantified.The more qualitative benefits, such as better process understanding and more challenging work for the operator are also described.Several full-scale experiences of how ICA has improved economy, ease of operation and robustness of plant operation are presented. The book emphasizes both unit process control and plant wide operation.

About the author (2005)

Gustaf Olsson, Professor Em. in Industrial Automation, Lund University, Sweden Since 2006 Gustaf is professor emeritus at Lund University, Sweden. Gustaf has devoted his research to control and automation in water systems, electrical power systems and process industries. From 2006 to 2008 he was part time professor in electrical power systems at Chalmers University of Technology, Sweden. Since 2006 he has been guest professor at the Technical University of Malaysia (UTM) and at the Tsinghua University in Beijing, China; about one month per year at each university. He is an honorary faculty member of the Exeter University in UK. Gustaf has served in various positions within IWA, the International Water Association. Between 2005 and 2010 he was the editor-in-chief of the journals Water Science and Technology and Water Science and Technology/Water Supply. From 2007 to 2010 he has been a member of the IWA Board of Directors. Gustaf has guided 23 PhDs and a few hundred MSc students to their exams. He has received the Lund University pedagogical award for distinguished achievements in the education." The Lund University engineering students have elected him as the teacher of the year. In 2010 he received the IWA Publication Award. Except in China and Malaysia he has spent extended periods as a guest professor and visiting researcher at universities and companies in the USA, Australia and Japan and has been invited as a guest lecturer in 19 countries outside Sweden. He has authored six books some of them published in English, Russian, German and Chinese and about 160 scientific publications.
