Description: The most common activated sludge operating problems causing poor plant performance are related to solids separation. Especially common are bulking and foaming. Without a proper scientific foundation to support the efforts of wastewater treatment plant management, many attempts to thwart bulking and foaming have failed. Manual on Solving Activated Sludge Bulking, Foaming, and Other Solids Separation Problems provides the critical scientific and practical underpinnings needed to understand and combat these problems. The third edition of this flagship text is a comprehensive, concise guide to the microbiological and technical aspects of controlling all types of solid separation problems. The scientific theory is applied to real-world scenarios, greatly increasing the number of real-world examples of successful control methods. New information is also included on filamentous organism growth and its application in the control of sludge bulking and foaming. Now plant operators, regulators and wastewater engineers have a complete guide for battling these formidable design and operating problems.

Description: Downstream is an arresting vision of the Colorado River by renowned landscape photographer Karen Halverson. The Colorado, crucial to development in the West, is at once wilderness, natural resource, recreation area, and wasteland. In seventy large-format color photographs, Halverson captures the river's natural majesty as well as the strange and unexpected beauty of its altered state. The images take us on an intimate exploration of the Colorado's entire length--from its rugged upstream canyons, to its dams and reservoirs, to where it disappears into the desert, entirely consumed. In an insightful, personal introduction to the photographs, Halverson tells how she explored the Colorado--accessing it by car, on foot, and by raft--while learning about its transformation into a complex water delivery system. In a lyrical foreword, historian William Deverell sets the photographs in the illuminating context of Colorado River history and discovery. In both images and prose, the book gives an extraordinary view of the Colorado's great and enduring splendor and a clear-eyed look at the many ironies contained in its waters.

Description: Covering wetlands soils from Florida to Alaska, Wetland Soils: Genesis, Hydrology, Landscapes, and Classification provides information on all types of hydric soils. With contributions from soil scientists who have extensive field experience, the book focuses on the soil morphology of the wet soils that cover most wetlands from the subtropics northward. No previous book has been devoted solely to the subject of hydric soils and their landscapes. The book is well organized and divided into three parts. Part I examines the basic concepts, processes, and properties of aspects of hydric soils that pertain to virtually any hydric soil. It provides a general overview and important terms and concepts. Part II covers the soils in specific kinds of wetlands and the different functions they perform. Part III emphasizes special wetlands conditions such as soils composed of sand, organic soils in northern North America, prairie wetlands, wetlands in saline situations, dry climates, and wetlands with modified hydrology. Whether you are an expert in soil science, or just need a crash course, this reference prepares you to work with real wetlands-outdoors. Written for scientists without a background in soil science and comprehensive in scope, Wetlands Soils: Genesis, Hydrology, Landscapes, and Classification provides basic and advanced coverage, explaining the fundamentals of hydric soils in terms even a non-soil scientist can understand.

Description: A detailed account of the biology and ecology of vascular wetland plants and their applications in wetland plant science, Wetland Plants: Biology and Ecology presents a synthesis of wetland plant studies and reviews from biology, physiology, evolution, genetics, community and population ecology, environmental science, and engineering. It provides a thorough discussion of the range of wetland plants adaptations to conditions such as life in water or saturated soils, high salt or high sulfur, as well as low light and low carbon dioxide levels. The authors include the latest research on the development of plant communities in newly restored or created wetlands and on the use of wetland plants as indicators of ecological integrity and of wetland boundaries. Over 140 figures, including over 70 original photographs, allow you to visualize the concepts, 40 tables give you easy access to definitions and data, and international examples provide you with a broad base of information. The growing consensus in wetlands literature and research suggests that methods are needed to assess the ecological health or integrity of wetlands, to set goals for wetland restoration, and to track the status and trends of wetlands. Wetland plants are emerging as important indicators, and becoming an important part of this research. Wetland Plants: Biology and Ecology contains up-to-date information on this increasingly important area in wetlands technology.

Description: This volume features the best and most influential essays by Donald Pisani, one of our nation's leading environmental and western historians. Collectively, the essays highlight the central role played by land, water, and timber allocation in the American West and show how efforts to achieve justice and efficiency were compromised by the region's obsession with achieving rapid economic growth. Pisani's work underscores the importance of natural resources to the American vision of opportunity and social progress, as well as the limits of federal influence in resolving the complex tensions between national and local control, between government regulation and laissez-faire capitalism, between democratic and corporate power, and between development and conservation. His work reminds us that westerners, ever wary of any form of centralized planning, have been far more supportive of the marketplace than government direction, and he demonstrates just how difficult it is to alter natural resource policies to keep pace with changing times and values. For those already familiar with Pisani or those coming to him for the first time, this is an invaluable volume. This book is part of the Development of Western Resources series.

Description: The water and power industries, including the most capital-intensive producers of goods and services in our economy, are exposed to financial risks of staggering proportions. With projects that are routinely large and require long-term planning, and with demand and supply often highly volatile, costs regularly defy prediction. Still, there has been little explicit analysis of financial risk in the water and power industries. In this work, C. Vaughan Jones provides a comprehensive discussion of financial risk and risk analysis for these utilities. Writing in clear, straightforward language, he explores the application of risk analysis to construction projects, rate-setting and price effects, and customer characteristics. In developing a method for evaluating risk, Jones brings together material from business, engineering, economics, demography, probability theory, computer simulation, and policy studies. The materials are organized around risk factors affecting costs and revenues, and support a practical analysis with spreadsheet and simulation examples. Separate chapters present findings relating to the variability of construction costs, customer demand, and population growth. Together with qualitative information about risks, these chapters offer suggestions about quantitative representation of relevant patterns of variability of key risk sources. The techniques are integrated in simulation models dealing with contract risk, the evaluation of sinking funds and amortization schedules, and long-run capacity planning. The concluding chapters summarize major findings, consider issues of reliability and validation, and discuss the way in which this analysis can be applied to a variety of infrastructure investments. Finance and investment professionals and students in business and finance studies will find this work to be a useful reference tool. For public and academic libraries, it will represent a valuable addition to their collections.

Description: Graywater: The Next Wave is a complete guide to conserving laundry and bath water-"graywater"-for use in landscape watering. For the novice it offers complete details on the advantages, components and methods for conserving one of our most valuable resources. Those already familiar with the benefits of reclaiming graywater will find this up-to-date guide has the latest information for installing and maintaining several different types of graywater systems. A step-by-step guide and photographs teach you how to install a near-surface drainfield at a fraction of the cost of the methods employed in conventional graywater systems. Newly researched methods of graywater disinfectant are also detailed, which have less impact on plants and the environment. Graywater: The Next Wave also includes a complete guide for homeowners with septic systems, which covers the primary reasons for their failure, and steps for preventing their failure. The life of a septic system can be greatly extended by the use of a graywater system. In many cases a failing septic system can be restored to normal operation by reducing the amount of liquids and detergents flowing into it by installing a graywater system. Graywater is also spelled gray water, grey water, and greywater.
