Instrumentation, Control and Automation in Wastewater Systems


Book Description

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. Scientific & Technical Report No. 15







Instrumentation Control and Automation for Waste-Water Treatment Systems


Book Description

Progress in Water Technology, Volume 6: Instrumentation Control and Automation for Waste-Water Treatment Systems contains the proceedings of the International Association on Water Pollution Research Workshop on Instrumentation Control and Automation for Waste-water Treatment Systems, held in London in September 1973. Contributors review major advances that have been made in instrumentation control and automation of wastewater treatment. This volume consists of 70 chapters organized into six sections. The work of the Directorate General Water Engineering in the Department of the Environment in the UK and the Environmental Protection Agency in the United States with respect to promotion of instrumentation, control, and automation for wastewater treatment systems is first discussed. This discussion is followed by a chapter that describes the effects of water pollution legislation in The Netherlands on the selection of wastewater treatment plants and their consequences for consulting engineers regarding process, technical, and economical feasibility. A real-time water quality management system for a major river in Pennsylvania is also considered, along with effluent control and instrumentation in Europe. The chapters that follow focus on instrumentation and control problems in the design of a modern sewage works; installation of field equipment in automated process control systems; process control for biological treatment of organic industrial wastewaters; and the use of computers to control sewage treatment. This book will be of interest to authorities, planners, and policymakers involved in wastewater treatment and water pollution control.




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


Book Description

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.




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


Book Description

Instrumentation, Control and Automation of Water and Wastewater Treatment and Transport Systems 1993 comprises a selection of manuscripts on the development of control strategies and their applications and on the status and future directions of Instrumentation, Control, and Automation (ICA) in the water and wastewater industry. The book starts by providing an overview of the status, the constraints and the future prospects for ICA in water and wastewater treatment and transport based on the survey responses of experts from 16 different countries. The text continues by presenting the need for dynamic modeling and simulation software to assist operations staff in developing effective instrumentation control strategies and to provide a training environment for the evaluation of such strategies. The book also covers the critical variables in system success; the use of an enterprise-wide computing that emphasizes the importance of strategic planning, performance measures, and human factors associated with the suggested implementation of applied technology; and the use of part-time unmanned operation at a large wastewater treatment plant. A functional approach based on the utility's water and wastewater functional requirements; the collection system monitoring and control; water distribution and control systems; dynamic modeling and simulation; and process control strategy and development are also considered. This book will be beneficial to biochemists, wastewater technologists, and public health authorities.

Benchmarking of Control Strategies for Wastewater Treatment Plants


Book Description

Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously, meeting stricter and stricter regulations. Many control strategies have been proposed in the literature for improved and more efficient operation of wastewater treatment plants. Unfortunately, their evaluation and comparison – either practical or based on simulation – is difficult. This is partly due to the variability of the influent, to the complexity of the biological and biochemical phenomena and to the large range of time constants (from a few minutes to several days). The lack of standard evaluation criteria is also a tremendous disadvantage. To really enhance the acceptance of innovative control strategies, such an evaluation needs to be based on a rigorous methodology including a simulation model, plant layout, controllers, sensors, performance criteria and test procedures, i.e. a complete benchmarking protocol. This book is a Scientific and Technical Report produced by the IWA Task Group on Benchmarking of Control Strategies for Wastewater Treatment Plants. The goal of the Task Group includes developing models and simulation tools that encompass the most typical unit processes within a wastewater treatment system (primary treatment, activated sludge, sludge treatment, etc.), as well as tools that will enable the evaluation of long-term control strategies and monitoring tasks (i.e. automatic detection of sensor and process faults). Work on these extensions has been carried out by the Task Group during the past five years, and the main results are summarized in Benchmarking of Control Strategies for Wastewater Treatment Plants. Besides a description of the final version of the already well-known Benchmark Simulation Model no. 1 (BSM1), the book includes the Benchmark Simulation Model no. 1 Long-Term (BSM1_LT) – with focus on benchmarking of process monitoring tasks – and the plant-wide Benchmark Simulation Model no. 2 (BSM2).
