This book was released on 2016-06-06 with total page 574 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.

This book was released on 2011-06-27 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: by Professor Poul Harremoes Environmental engineering has been a discipline dominated by empirical approaches to engineering. Historically speaking, the development of urban drainage structures was very successful on the basis of pure empiricism. Just think of the impressive structures built by the Romans long before the discipline of hydraulics came into being. The fact is that the Romans did not know much about the theories of hydraulics, which were discovered as late as the mid-1800s. However, with the Renaissance came a new era. Astronomy (Galileos) and basic physics (Newton) started the scientific revolution and in the mid-1800s Navier and Stokes developed the application of Newtons laws to hydrodynamics, and later, St. Venant the first basic physics description of the motion of water in open channels. The combination of basic physical understanding of the phenomena involved in the flow of water in pipes and the experience gained by "trial and error", the engineering approach to urban drainage improved the design and performance of the engineering drainage infrastructure. However, due to the mathematical complications of the basic equations, solutions were available only to quite simple cases of practical significance until the introduction of new principles of calculation made possible by computers and their ability to crunch numbers. Now even intricate hydraulic phenomena can be simulated with a reasonable degree of confidence that the simulations are in agreement with performance in practice, if the models are adequately calibrated with sample performance data.

Book excerpt: The growing awareness of environmental problems provided the stimulus for this 4th International Symposium on Biotechnology, Interbiotech '90, to address many aspects of the relationship between biotechnology and the environment. The papers are mainly devoted to the contribution of biotechnology in solving environmental problems, including biological waste water treatment, utilization of municipal sewage sludge, detoxification of polluted soil and complex utilization of lignocellulosic wastes. There is examination of possible dangers in such cases as the release of r-DNA organisms into the environment. The relationship of biotechnology and energy (e.g. biogas, landfill gas fuel, photosynthetic systems for fuel production) is also discussed.

Download or read book Activated Sludge written by Tim Hobson and published by . This book was released on 2009-12-08 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the book's introduction: This is not an introductory text about activated sludge. In this book, we discuss the observation, testing, and calculation procedures that provide data about the status of the activated sludge process. In addition, we discuss in depth how to apply this data to the business of controlling your activated sludge treatment process. Basic activated sludge concepts are addressed in this book in the context of process evaluation and control. We focus our efforts on discussing a basic, practical system of control for the process. The procedures discussed in this manual are equally applicable to all variations. An operator must have information about settleability, dissolved oxygen concentration, solids concentration, effluent quality, and clarifier sludge levels for consistent, efficient process performance of every type of activated sludge process. These procedures are covered in detail. The procedures discussed are based on work done by E. B. Mallory in the 1930's and 40's and further developed by Alfred W. West while he was head of the Operational Technology Branch of the Environmental Protection Agency in the 1960's and 70's. The system, with some modifications by this author, is frequently called the "West Method" or "Sludge Quality Method" of activated sludge process control because operational controls adjustments are based on the sludge quality existing in your facility rather than on arbitrary values.

The manual can be used independantly but when used in combination with the CD-ROM, it makes a unique tool for process operators to diagnose and solve operational problems. It is also a valuable educational and training package for universities and post experience courses. Click here for more details about the CD-ROM Process stability and final effluent quality largely depend upon the composition of the biomass in an activated sludge plant. Operational problems such as bulking and scum formation occur when the wrong micro-organisms are dominating the sludge population. Microscopic sludge investigation is therefore essential for process control and stable plant operation. The manual outlines the theoretical framework, extensively illustrated with full-colour micrographs.
