This book was released on 2016-06-06 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Spellman s Standard Handbook for Wastewater Operators written by Frank R. Spellman and published by CRC Press. This book was released on 1999-04-28 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spellman's Standard Handbook for Wastewater Operators Volume 1 Fundamental-Level provides information and unit process trouble-shooting guidance required on a daily basis, not only by the plant manager, plant superintendent, chief operator, lab technician, maintenance operator, but more importantly by and for the plant operator, and those in preparation for taking the entry-level Class IV/Class III or Grade I/II operator examinations. This handbook was prepared to help operators obtain licensing and to operate wastewater treatment plants properly. It can be used as a textbook in technical training courses in technical schools and at the junior college level. Spellman's Standard Handbook for Wastewater Operators is the first volume of a new study guide and readily accessible source of information for review in preparing wastewater personnel for operator certification and licensure. These handbooks are resource manuals and troubleshooting guides that contain wastewater treatment information, data, operational material, process control procedures and problem solving, safety and health information, new trends in wastewater treatment administration and technology, and numerous sample problem-solving practice sets, many based on actual tests. The Handbooks' goal is to enhance the understanding, awareness and abilities of practicing operators and those who want to become operators. The three volumes are designed to build on each other, providing increasingly advanced information. For persons preparing for operator's licensing, this is critical, because wastewater treatment is a complex process. For licensed veteran operators, continuous review is also critical, because wastewater treatment is an evolving, dynamic, ever-changing field. Spellman's Standard Handbooks provide the vehicle for reaching these goals.

Download or read book Microscopic Examination for the Operation and Control of Wastewater Treatment Plants written by N. J. Horan and published by . This book was released on 2007 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain types of waste are plagued by filamentous bacteria. Rountine monitoring of the activates sludge floc can observe the build up of such bacteria which can indicate the onset of bulking or foaming, and can suggest control strategies to minimise the impact of such an incident. Microscopic examination of the sludge is a valuable tool for efficient water plant operation, and most plants have microscopes for this purpose. Most plant operators, however, do not have the biological background to use this facility to its full potential. If a few basic rules are followed, a lot of valuable information can be quickly obtained. This handbook shows how to carry out a monitoring programme, interpret the results, and take necessary steps to minimise the impact of a bulking incident.
Download or read book Settleability Problems and Loss of Solids in the Activated Sludge Process written by Michael H. Gerardi and published by John Wiley & Sons. This book was released on 2003-06-17 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The activated sludge process is the most versatile, commonly used wastewater treatment system in North America; however, many activated sludge processes frequently experience operational problems related to poor compaction or settleability of secondary solids and loss of secondary solids from the clarifier. Eschewing the technical jargon and copious chemical equations found in the majority of wastewater studies, Settleability Problems and Loss of Solids in the Activated Sludge Process speaks directly to plant operators, showing them how to identify and solve common problems and achieve maximum efficiency. Michael H. Gerardi’s hands-on guide addresses the most common plant operational problems, such as increased costs, loss of treatment efficiency, and permit violations. Using numerous tables and illustrations, Settleability Problems provides microscopic and analytical techniques for troubleshooting and identifying the conditions responsible for settleability problems and loss of solids. It includes pictures of wet mounts and smears of acceptable and unacceptable microscopic conditions of the activated sludge and presents corrective measures for operational problems. Chapters include: Undesired Filamentous Growth Nutrient-Deficient Floc Particles Denitrification Slug Discharge of Soluble cBOD Viscous Bulking or Zoogloeal Growth Production and Accumulation of Foam and Scum Volume II in the series, Settleability Problems will prove to be of unparalleled value to wastewater treatment plant operators as well as students of wastewater microbiology.
Download or read book Microbial Ecology of Activated Sludge written by Robert Seviour and published by IWA Publishing. This book was released on 2010-01-15 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial Ecology of Activated Sludge, written for both microbiologists and engineers, critically reviews our current understanding of the microbiology of activated sludge, the most commonly used process for treating both domestic and industrial wastes. The contributors are all internationally recognized as leading research workers in activated sludge microbiology, and all have made valuable contributions to our present understanding of the process. The book pays particular attention to how the application of molecular methods has changed our perceptions of the identity of the filamentous bacteria causing the operational disorders of bulking and foaming, and the bacteria responsible for nitrification and denitrification and phosphorus accumulation in nutrient removal processes. Special attention is given to how it is now becoming possible to relate the composition of the community of microbes present in activated sludge, and the in situ function of individual populations there, and how such information might be used to manage and control these systems better. Detailed descriptions of some of these molecular methods are provided to allow newcomers to this field of study an opportunity to apply them in their research. Comprehensive descriptions of organisms of interest and importance are also given, together with high quality photos of activated sludge microbes. Activated sludge processes have been used globally for nearly 100 years, and yet we still know very little of how they work. In the past 15 years the advent of molecular culture independent methods of study have provided tools enabling microbiologists to understand which organisms are present in activated sludge, and critically, what they might be doing there. Microbial Ecology of Activated Sludge will be the first book available to deal comprehensively with the very exciting new information from applying these methods, and their impact on how we now view microbiologically mediated processes taking place there. As such it will be essential reading for microbial ecologists, environmental biotechnologists and engineers involved in designing and managing these plants. It will also be suitable for postgraduate students working in this field.
