Managing wastewater is a necessary task for small businesses and production facilities, as well as for large industrial firms. Industrial Wastewater Treatment: A Guidebook presents an approach to successful selection, development, implementation, and operation of industrial wastewater treatment systems for facilities of all sizes. It explains how to determine various properties about wastewater, including how it is generated, what its constituents are, whether it meets regulatory requirements, and whether or not it can be recycled. It describes methodologies for developing and maintaining a suitable treatment program, determined by the type of company under consideration. Examples of treatment systems which have been installed in various types of businesses over the past several years are presented in a manner that clearly illustrates successful treatment methods.

This book was first published in 1983. It provides a comprehensive overview of irrigation technologies, techniques and economics, tailored to a multitude of different crops.

Although nosocomial, or hospital-acquired, infections have been well cataloged and are fairly well understood, traditional solutions have failed to completely eliminate the problem. Even the most modern hospitals find themselves stymied by the persistence of these pathogens in hospital wards and operating rooms. The degree to which most of these infections are airborne is not known, but a growing body of evidence indicates that airborne transmission plays a role in many hospital-acquired infections. Addressing one of the most important topics in health care, Hospital Airborne Infection Control is the first book to deal with the control of airborne nosocomial infections in detail. It identifies all pathogens known or suspected to be airborne, along with their sources in hospital environments. It also summarizes all epidemiological evidence for airborne transmission. The text addresses respiratory, surgical site, burn wound, immunocompromised, pediatric, nursing home, and non-respiratory infections. In each category, an extensive number of examples show that inhalation is not the only airborne route by which infections may be transmitted. Noting that airborne transmission and surface contamination are virtually inseparable, the author emphasizes that both air and surface disinfection, including hand hygiene, are important factors in controlling the transmission of airborne disease. He also proposes a variety of new solutions and technologies, including ultraviolet, ionization, ozone, plasma, and vegetative air cleaning systems. A compendium of scientific and medical information, this book helps hospitals control nosocomial infections and outbreaks spread by the airborne route as well as by direct contact and contact with fomites or contaminated equipment.

Atomic weapons and nuclear power plants: they promised to ensure world peace and provide efficient energy to Americans during the 1940s and 1950s. Meanwhile, the post war prosperity led to the most dramatic population explosion ever witnessed in the United States: the "baby boomer" generation.Times and politics may change, but many baby boomers-as well as their descendants-now live with an unforeseen result of the nuclear age. Rates of immune-related diseases have risen steadily throughout the past few decades, from allergies to cancer. While advances in medical care have kept death rates relatively low, the increased prevalence of certain diseases cannot be ignored.Low Level Radiation and Immune System Damage: An Atomic Era Legacy establishes an undeniable connection between the nuclear build up of the past and the widespread health problems seen today. While baby boomers were growing up in the 40s and 50s, above-ground atomic bomb tests and start ups of civilian nuclear power plants were carried out without fear of public exposure to radioactive emissions.Although the consequences of low-level radiation are still hotly debated, Mangano's research findings emphasize a direct link between nuclear exposure and immune system deficiency. In addition to substantial data on immune disease trends among Americans born between the mid-1940s and mid-1960s, Mangano also examines similar issues concerning baby boomer children and grandchildren. Health professionals, environmentalists, historians and students alike will find much to learn from these pages.As America and the world come to terms with the post-Cold War era, there are still many lessons to recognize, consider, and learn from the still-recent past. Low Level Radiation and Immune System Damage: An Atomic Era Legacy explores a relentless trend that will not soon be over-with potential repercussions into the 21st century.

The loss of water from lakes, rivers, oceans, vegetation, and the earth, as well as man-made structures such as reservoirs and irrigation conduits, is a major concern of hydrologists and irrigation specialists. This loss, compounded by the lack of usable water in some areas, indicates a need for field and laboratory research that will contribute to the understanding of the processes and parameters that comprise and contribute to evaporation.This book emphasizes the process of the air-water interface and discusses such important topics as evaporation and condensation coefficients of water, heat and mass transfer, surface temperature, interfacial tension, convection, diffusion, thermal gradients, wind-generated waves, and the roles that these processes play in evaporation. The book also discusses subjects such as methods for suppressing evaporation using films, water vapor distribution, wind tunnel investigations, evaporation from water drops, preparation of pure water, molecular diffusion, the eddy-correlation method, and evaporation estimation methods. The book will be of considerable value to hydrologists, irrigation specialists, meteorologists, civil engineers, chemical engineers, hydraulic engineers, water resources specialists, water conservation specialists, geophysicists, environmental engineers, and anyone interested in understanding the evaporation of water and its consequences.

The purpose of this book is to promote useful knowledge in the field of cryogenics. To accomplish this, the manuscript presents a composite of the state-of-the-art knowledge, research, and application of cryogenic processes.

This book represents the proceedings of the firstGreat Lakes Costal Wetlands Colloquium (November 5-7, 1984; East Lansing, Michigan). The theme wasNatural and Manipulated Water Levels in Great Lakes Wetlands. This material constitutes both Great Lakes wetlands and the state of understanding about them. It is intended to provide fisheries and wildlife biologists, ecologists, aquatic resource managers and planners and environmental scientists information about the coastal wetlands in regard to eight priority areas. The colloquium and publication of the proceedings were cosponsored by Sea Grant Program and Environment Canada.

An Approach to Improving Decision-Making in Wetland Restoration and Creation succinctly compares populations of natural and created wetlands to determine whether restored wetlands successfully replace wetlands lost to development or other pressures. The book also presents strategies for mitigation of wetland losses, site selection for wetland restoration projects, and assessment of the level of attainable function for restored wetlands. The book is a significant resource for helping wetland professionals, planners, and ecologists formulate decisions affecting the creation and restoration of wetlands.

A review of the nation's new coverages serves as a ready reminder that drinking water safety is more than regional of local concern. In recent times, the print media alone has drawn attention to barium, bacteria, heavy metals, and increasingly organic contaminants, in public water supplies located in Florida, Rhode Island, Texas, Oregon, Illinois, Minnesota, North Carolina, Michigan, and California, to name a few. In an effort to address one of the major issues confronting the future of the nation's drinking water supplies, chemical contamination, the Drinking Water Research Foundation and the American Chemical Society presented the symposium, "Safe Drinking Water: the Impact of Chemicals on a Limited Resource." To add balance to the total presentation, two papers were included that were not part of the symposium. Many questions as to the public significance of hundreds of organic chemicals known to be present in the national drinking water supply are waiting to be answered. In some areas of the country, aid rain-induced alterations of the natural leaching process represent an unexplored potential source of toxic pollutants. Finding workable ways to clean up the water supply will be an ongoing task. Addressing these questions, as well as investigating how other countries are responding to these problems, the alternate sources available, such as bottled water, and point of use devices, the presenters in this symposium have attempted to explain the problems, situation, and alternatives. As progress is made in one area, setbacks will occur in another. As we eliminate problems thought chemical technology, we often create others, such as contamination of our waters. While all the situations, problems, and alternatives are not discussed in these proceedings, it is hoped that some attention will be brought to the public, government, and private sectors so that future work will be done to assure the nation of safe drinking water resources.

In a simple, straightforward manner, this book presents most of the major process units for wastewater treatment, addressing what the unit is and how it basically works. Along with that it provides some of the math problems associated with each unit. Each math problem, presented in English units, is usually followed by a nearly identical problem in metric units. It also presents new concepts, such as information on process microbiology, in a comfortable language so the reader can concentrate on the subject matter instead of the language used to present it. Simplified Wastewater Treatment Plant Operations provides comprehensive and technically accurate wastewater information in a clear and concise manner. The related workbook provides readers with a place to write in answers and work out problem solutions.

Supplementary cementing materials (SCMs), such as fly ash, slag, silica fume, and natural pozzolans, make a significant difference to the properties of concrete but are rarely understood in any detail. SCMs can influence the mechanical properties of concrete and improve its durability in aggressive environments. Supplementary Cementing Materials in Concrete covers the chemical, physical, and mineralogical properties of SCMs; their chemical reactions; and the resulting changes in the microstructure of concrete. The author links the properties of the material at the microstructural level with its behavior in laboratory tests, and, in turn, to the performance of the material in concrete structures under field exposure. He explains how SCMs influence the mechanical properties of concrete and improve its durability and also covers how various SCMs influence hydration reactions and the evolution of the pore structure and pore-solution composition. However, SCMs are not a panacea for concrete and improper use may be injurious to certain properties. Achieving the maximum benefit from SCMs requires an understanding of the materials and how they impact concrete properties under various conditions. Drawing on the author's 30 years of experience, this book helps engineers and practitioners to optimize the use of supplementary cementing materials to improve concrete performance.

As mankind searches for energy alternatives with minimal environmental consequences and acceptable cost, it is necessary to identify valid areas of endeavor that can activate favorable energy sources and technological developments. Toward that end, The Dynamics of Energy: Supply, Conversion, and Utilization develops competence in energy matters on three levels: basic concepts, essential computations, and dynamic modeling. The book reviews the laws of thermodynamics and rate relationships between flows and gradients as a foundation for subsequent topics. Using dynamic analysis, it examines the potential of current energy sources to serve the needs of a growing world economy. The text also describes key fossil conversion, renewable conversion, and utilization technologies. It presents a technique to assess efficiencies from ground (or harvest) to end use, explores the effects of energy use on the environment, and offers an introduction to dynamic modeling. The book concludes with a description of energy technologies that, if suitably employed, could configure a sustainable energy future. Studying the dynamics of thermal systems is conducive to ascertaining what technologies could indeed make a difference for a desirable energy future. Suitable response time to demand and acceptable fuel lifetimes are necessary conditions for energy systems to compete in the marketplace. The planning effort that should lead the energy endeavor requires projection of the time span of pollution effects. Harnessing the flexibility and speed of VisSim (TM) for dynamic modeling, this book provides the tools to model most thermal systems with moderate complexity. It also evaluates energy supplies, conversion, and end use.

The growth in the world's nuclear industry, motivated by peaking world oil supplies, concerns about the greenhouse effect, and domestic needs for energy independence, has resulted in a heightened focus on the need for next-generation nuclear fuel-cycle technologies. Ion Exchange and Solvent Extraction: A Series of Advances, Volume 19 provides a comprehensive look at the state of the science underlying solvent extraction in its role as the most powerful separation technique for the reprocessing of commercial spent nuclear fuel. Capturing the current technology and scientific progress as it exists today and looking ahead to potential developments, the book examines the overall state of solvent extraction in reprocessing, new molecules for increased selectivity and performance, methods for predicting extractant properties, and actinide-lanthanide group separation. The contributors also explore the simultaneous extraction of radionuclides by mixing extractants, the cause and nature of third-phase formation, the effects of radiation on the solvent and its performance, analytical techniques for measuring process concentrations, new centrifugal contactors for more efficient processing, and new chemistry using novel media. The long-term vision of many professionals in the field entails a proliferation-free nuclear energy economy in which little or no waste is stored or released into the environment and all potential energy values in spent nuclear fuel are recycled. This text opens a window on that possibility, offering insight from world leaders on the cutting edge of nuclear research.

Pollution of water sources with emerging contaminants (micropollutants) is a fact known worldwide. Although the risks of micropollutants in sources of water are partly recognized, interpretation of consequences are controversial; thus, the future effects of altered water with micropollutants remains uncertain and may constitute a point of concern for human beings when potable water consumption is involved. Therefore, many drinking water utilities target as an important goal high-quality drinking water production to lessen quality considerations that may arise from the consumers. In this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.

Whether addressing pollution problems or helping protect a specific use, watershed associations are finding that the competition for funds is getting harder. While we can grasp the value of our streams for fishing or kayaking and other services, or their cultural value, or their value to an ecosystem, putting a dollar value on those benefits is not an easy task, but it is sometimes a necessary one. A handbook for advocates and stakeholders, Environmental Economics for Watershed Restoration provides guidance to those who are interested in understanding and incorporating economic valuation in project prioritization and other decision-making aspects of stream or watershed restoration. It provides background on the types of ecological goods and services that are often valued and details the types of questions that must be asked in watershed project analysis. The book allows those who are not economists to be comfortable discussing things like contingent valuation, marginal costs, nonmarket goods, and other terms needed to satisfy the economic analysis requirements often needed to secure funding for projects. In some cases, economic analysis does require input from a trained economist, but in many cases the analysis needed to get a grip on the problem can be tackled by someone familiar with the situation, as long as he or she has access to essential economic guidance. Environmental Economics for Watershed Restoration can provide that guidance.

The natural scarcity of water in arid and semiarid regions, aggravated by man-made factors, makes it difficult to achieve a reliable water resources supply. Communities in these areas pay the price for thousands of years of water manipulation. Presenting important insight into the complexities of arid region hydrology, Engineering Hydrology of Arid and Semi-Arid Regions explores the key components for formulating and implementing integrated management approaches in catchment (wadi) systems. The book introduces the engineering hydrology of arid and semi-arid regions, covering meteorological processes and hydrology. The author discusses precipitation and precipitation losses, catchment characteristics, and runoff estimation methods. He also examines streamflow measurements and hydrographs, flood routing, and groundwater hydrology, including the basic equations of groundwater flow and analytic solutions describing flow aquifers, pumping tests, and salt water intrusion. Building on this foundation, the book then delineates sediment yield in watersheds and streams and the design of hydraulic structures for protection and management of water resources systems. It includes case studies, conversion tables, and modeling software. During the last two decades, research efforts and networking have enhanced the state of knowledge about arid and semi-arid areas, especially watershed and catchment systems. Pulling this information together into a comprehensive resource, this book provides a better understanding of wadi hydrology, capacity-building processes, water education and training, and institutional development. This understanding can then be used to select the appropriate tools to support water management and optimize the sustainable use of water resources.

A successful modern heavy metal control program for any industry will include not only traditional water pollution control, but also air pollution control, soil conservation, site remediation, groundwater protection, public health management, solid waste disposal, and combined industrial-municipal heavy metal waste management. In fact, it should be a total environmental control program. Comprehensive in scope, Heavy Metals in the Environment provides technical and economical information on the development of a feasible total heavy metal control program that can benefit industry and local municipalities. The book discusses the importance and contamination of metals such as lead, chromium, cadmium, zinc, copper, nickel, iron, and mercury. It covers important research of metals in the environment, the processes and mechanisms for metals control and removal, the environmental behavior and effects of engineered metal and metal oxide nanoparticles, environmental geochemistry of high arsenic aquifer systems, nano-technology applications in metal ion adsorption, biosorption of metals, and heavy metal removal by expopolysaccharide-producing cyanobacteria. The authors delineate technologies for metals treatment and management, metal bearing effluents, metal-contaminated solid wastes, metal finishing industry wastes and brownfield sites, and arsenic-contaminated groundwater streams. They also discuss control, treatment, and management of metal emissions from motor vehicles. The authors reflect the breadth of the field and draw on personal experiences to provide an in-depth presentation of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends for each industrial or commercial operation. The methodologies and technologies discussed are directly applicable to the waste management problems that must be met in all industries.

Fingerponds are earthen ponds dug at the edge of natural wetlands and stocked naturally with wild fish during flooding. They preserve the wetland environment in which they are situated while maintaining a productive culture system. In this study, the importance of organic manure applications in enhancing nutrient levels, phytoplankton and periphyton productivities and ultimately fish production was examined in experimental Fingerponds set up with the participation of local communities in Uganda. Results show that organic manures enhance algal development and fish production in Fingerponds, but close monitoring and control are needed. Fish yields in Fingerponds can be enhanced to 1500 - 2800 kg/ha over a functional period of 200 to 300 days using animal manure (e.g. chicken), fermented green manure and artificial substrates for periphyton development. Good management practices are required to regulate pond inputs and conditions. High clay turbidity, nitrogen limitation and high recruitment of fish can limit fish production. Overall, Fingerponds were shown to be an effective addition to protein production for poor riparian communities in East Africa and are recommended for adoption.
