Instrumentation, Control and Automation of Water and Wastewater Treatment and Transport Systems 1993

About this book

Advances in sensor development and computer technology, accompanied by decreasing hardware costs, have enabled considerable energy savings and the upgrading of existing water treatment/transport systems by identifying and correcting design and operational deficiencies. These technological advances have also provided the tools to optimise the design and operation of new facilities. These facts constituted the focus of the sixth in a highly successful series of international workshops. The 57 invited and selected articles cover: the management of ICA implementation; collection systems monitoring and control; water distribution control systems dynamic modelling and simulation; process control strategies; fuzzy control; respirometry-based process control; instrumentation applications and maintenance; control strategies application. The volume also includes a summary paper, drawing on 16 national status reports, which sets out the driving forces and constraints governing the application of ICA technologies around the world now and for the next 4 years. The result is an authoritative assessment of the present status and future directions of instrumentation, control and automation, which will be an essential reference for all interested in the use of these powerful technologies in the water and wastewater industry.
