Principles Of Water Quality

Principles of Water Quality presents the fundamental environmental processes that regulate the movement of materials in natural systems. This book is composed of 10 chapters that cover the chemical and microbiological processes that are operative on organic and inorganic constituents in water. This text deals first with water quality concepts, the development of criteria for water quality, and the determination of various contaminants' threshold levels that can be regulated by imposed standards. These topics are followed by descriptions of natural environmental processes, which include fundamental ecological principles and energy transfer in ecosystems resulting in species stability. The subsequent chapters are devoted to the organic and inorganic constituents that have become water quality problems, including toxic metals, inorganic nutrients, refractory organic compounds, and microorganisms. The discussion then shifts to the environmental impact of heated effluent discharges. The last three chapters focus on water quality modeling, standards, and management methods. These chapters also provide case studies using the phosphorus and the longitudinal dispersion models. This book is of value to advanced undergraduate or graduate students in environmental engineering and science, as well as in health-related disciplines.

Principles of Water Quality Control is the definitive student text in its field for 25 years, this new edition takes an environmental perspective that is highly relevant in the context of current public policy debates. New material also includes EU regulations and changes in the UK water industry since privatisation. The latest technological developments are also taken into account. As before, the book is intended for undergraduate courses in civil engineering and the environmental sciences, and as preliminary reading for postgraduate courses in public health engineering and water resources technology. It will also be a vital text for post-experience training and professional development, in particular for students preparing for the examinations of the Institute of Water Pollution Control and the Institution of Public Health Engineers. 25 Years worth of students can't be wrong International relevance Long established Pergamon title

This popular and widely used text has been thoroughly revised and expanded to include new chapters which reflect the growth in awareness of the problems of environmental pollution, the importance of environmental protection, and the vital role of water in the developing countries. Also covers the basic characteristics of waters and wastewaters, relevant aspects of microbiology, water pollution and the theoretical and practical basis of treatment processes. Includes numerous problems with answers. A useful list of further reading has been expanded (200 literature references approximately) to enable the reader to gain a wider appreciation of the topics covered.

This is a handbook for policy makers and environmental managers in water authorities and engineering companies engaged in water quality programmes, especially in developing countries. It is also suitable for use as a textbook or as training material for water quality management courses. It is a companion volume to Water Quality Assessment and Water Quality Monitoring.

This book teaches the fundamentals and principles which underlie the mathematical modeling techniques used to analyze the quality of surface waters. The text first provides an overview of the different bodies of water in which water quality problems need to be addressed before examining specific problems that occur across all bodies of water.

Recent legislation and more stringent effluent criteria are placing increased emphasis on effective water quality management. The past few years have seen increased emphasis on research and development into both conventional wastewa ter treatment processes as well as new and advanced technology. The purpose of this book is to present a concise summary of present theory, with emphasis on the application of that theory to both municipal and industrial wastewater treatment problems. This book, in large measure, is an updating of the author's previous books, Biological Waste Treatment, published by Pergaman Press, Industrial Water Pollution Control, published by McGraw-Hill, Water Quality Engineering for Practicing Engineers, published by Cahners Books. This book should be useful as a text for advanced undergraduate and graduate courses in Water Pollution Control, Industrial Waste Treatment, and Water Qual ity Management. The content of this book has been used as a text in Continuing Education Courses sponsored by Manhattan College, Vanderbilt University, and the American Institute of Chemical Engineers. A series of problems applying the theories as developed in the text are presented where appropriate. For in-depth study of specific topical areas the reader is referred to the cited book references at the end ofthe text.

Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
