Surfactants and Colloids in the Environment presents the proceedings of the General Meeting of the German Colloid Society (Kolloid-Gesellschaft) held at the Research Center of Julich (KFA), FRG, in 1993.
The volume emphasizes the importance of colloid chemistry in environmental research. Contributions on the physico-chemical behavior of colloids and surfaces in environmental technology demonstrate the high standard and usefulness of colloid science in this field: General colloid and environmental science complement each other. Thus, the detailed contributions in this volume will be useful toward solving some environmental problems."

The factors affecting water quality are many: The increasing buying power and health concerns of the world population contribute to the creation of new products whose production and disposal lead to the release of chemicals harmful to the environment; the ever-growing world population requires a steady food supply, which increases the pressure to use even more chemicals to control various crop pests; and due to climate change, head waters, rivers, and oceans are becoming increasingly warmer, acidic, and eutrophic as the result of carbod dioxide overload. Using specific examples, Water Quality and Resource Management will address the many challenges of providing clean water to the growing world population. It will also discuss the new technologies that are being developed, for example, to treat and reuse waste waters, and the innovative monitoring approaches that help scientists to assess water quality risks. Such risk assessments are urgently needed to help draft legislations and allow enforcement to ensure accessability to quality water for all. The structure of the book will be the following: Each chapter will provide information about a specific water environment and the challenges it faces. This will be followed by discussion of the pollution effects and actions taken to redress the situation. Finally, future trends will be discussed.

Mathematical models are the effective tool to solve different tasks predicting pollutant movement. The finite difference method is the oldest, but still remains widely used in hydrogeological practice. However, this method is not very useful to construct the new transport models because it cannot approximate the shape of remediation elements exactly. Therefore the book is concerned with the FEM (Finite Element Method) and BEM (Boundary Element Method), and also with the comparison of advantages of these methods in groundwater hydrology. The combination of the BEM and the random-walk particle tracking method, which seems to be a very useful tool to model the spread of pollution in groundwater, are also presented. The computer programmes have been developed on the basis of the theoretical backgrounds of these methods. They use the Visual C++ programming language for Windows 95/NT platform and will be included in the book.

During the last 10 years, there has been a `revolution' in ecosystem modelling. The generality and predictive power of our models have increased in a way that was inconceivable 10 years ago. This book describes a new generation of practically useful models that predict as well as one can measure - if one measures well. And yet, they are driven by readily available driving variables and have a general structure that applies to most types of pollutants in aquatic systems. The major reason for this development is, in fact, the Chernobyl accident. Large quantities of radiocesium were released in April/May 1986 as a pulse. To follow the pulse of radiocesium through ecosystem pathways has meant that important fluxes and mechanisms, i.e., ecosystem structures, have been revealed. It is important to stress that many of these new structures and equations are valid not just for radiocesium, but for most types of contaminants, e.g. for metals, nutrients and organics. This means that the models, methods (of building and testing models) and equations described in this book for lakes and coastal areas should be of great interest also to other ecosystem modellers. This book will be of considerable interest to: students in radioecology, geosciences and biology; environmental engineers; consultants; administrators and scientists interested in the spread, biouptake and ecosystem effects of chemical pollutants in aquatic ecosystems.

The development of water resources has proceeded at an amazing speed around the world in the last few decades. The hydraulic engineer has played his part: in constructing much larger artificial channels than ever before, larger and more sophisticated control structures, and systems of irrigation, drainage and water supply channels in which the flow by its nature is complex and unsteady requiring computer-based techniques at both the design and operation stage. It seemed appropriate to look briefly at some of the developments in hydraulic design resulting from this situation. Hence the idea of the Conference was formed. The Proceedings of the Conference show that hydraulic engineers have been able to acquire a very substantial base of design capability from the experience of the period referred to. The most outstanding development to have occurred is in the combination of physical and mathematical modelling, which in hydraulic engineering has followed a parallel path to that in other branches of engineering science. The Proceedings of this Conference will give to the reader an awareness of the current state of hydraulic design in open channel flow and open channel control structures. K.V.H. Smith Editor 1.

This book results from a NATO Advanced Research Workshop titled "Technological Innovations in CBRNE Sensing and Detection for Safety, Security, and Sustainability" held in Yerevan, Armenia in 2012. The objective was to discuss and exchange views as to how fusion of advanced technologies can lead to improved sensors/detectors in support of defense, security, and situational awareness. The chapters range from policy and implementation, advanced sensor platforms using stand-off (THz and optical) and point-contact methods for detection of chemical, nuclear, biological, nuclear and explosive agents and contaminants in water, to synthesis methods for several materials used for sensors. In view of asymmetric, kinetic, and distributed nature of threat vectors, an emphasis is placed to examine new generation of sensors/detectors that utilize an ecosystems of innovation and advanced sciences convergence in support of effective counter-measures against CBRNE threats. The book will be of considerable interest and value to those already pursuing or considering careers in the field of nanostructured materials, and sensing/detection of CBRNE agents and water-borne contaminants. For policy implementation and compliance standpoint, the book serves as a resource of several informative contributions. In general, it serves as a valuable source of information for those interested in how nanomaterials and nanotechnologies are advancing the field of sensing and detection using nexus of advanced technologies for scientists, technologists, policy makers, and soldiers and commanders.

The practical guide on what to do right when biological influences cause a sequencing batch reactor to go wrong

This richly illustrated, straightforward guide carries forth the legacy established by previous editions in the "Wiley Wastewater Microbiology" series by focusing attention on the mixed gathering of organisms cohabitating within a sequencing batching reactor (SBR), and the key roles their biology plays in this wastewater processing tank's function. With a clear, user-friendly presentation of complex subject matter, "Troubleshooting the Sequence Batch Reactor" first teaches plant operators how to differentiate the positive and expected organismal dynamics present in optimal SBR performance from the negative and damaging ones that create unhealthy sludge, and a stoppage in SBR operations. Next, Troubleshooting the Sequence Batch Reactor delivers all the tools necessary to get an SBR back on track and running safely. In this book you'll get:

Short-course situations tested by the author for the past fifteen years

Accessible material aimed at operators instead of design and consulting engineers

Essential information for understanding biological conditions such as aerobic, anoxic, and anaerobic/fermentative at the treatment process

Examination of the properties of protozoa (single-celled) and metazoa (multi-celled) organisms, and their significance in wastewater treatment

Devoid of overwhelming scientific jargon, chemical equations, and kinetics, this book simplifies details to provide quick instruction for plant operators on how to make more informed day-to-day process control decisions, how to troubleshoot confidently when SBR conditions become compromised, and how to act decisively when the problem is ultimately identified.

Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to "democratize" membrane filtration have been presented. Riverbank filtration is a "natural" filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

There is an extremely voluminous literature on radioactive waste and its disposal, much in the form of government-sponsored research reports. To wade through this mountain of literature is indeed a tedious task, and it is safe to speculate that very few, if any, individuals have the time to examine each report that has been issued during the preceding ten years. This book attempts to summarize much of this literature. Further, many workers in the geosciences have not received training in the nuclear sciences, and many nuclear scientists could be better versed in geology. In this book an attempt is made to cover some background material on radioactive wastes and geotoxicity that may not be an integral part of a geologist's training, and background material on geology and geochemistry for the nuclear scientist. The geochemical material is designed for both the geoscientist and the nuclear scientist. There is no specific level for this book. Certainly, it should be useful to advanced undergraduates and graduates studying geology and nuclear science. It does not pretend to cover a tremendous amount of detail in all subjects, yet the references cited provide the necessary source materials for follow-up study. It is my intention that the reader of this book will have a better, broader understanding of the geochemical aspects of radioactive waste disposal than is otherwise available in anyone source.

In the U.S., approximately two-thirds of the coastal rivers and bays are moderately to severely degraded from nutrient pollution. The contributors to this book use long-term data sets to discuss the interactions among biological, ecological, chemical, and physical processes, and discuss what is known about nutrient inputs to the bay ecosystem, the impacts related to nutrient inputs, and how the ecosystem might respond to a sudden reduction in these inputs.

The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology impacts all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies..., new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. The environmental aspects of all of our society's activities are extremely important if the countryside; the sea and wildernesses are to be fully enjoyed by future generations. Urban waste in all its manifestations presents a particularly difficult disposal problem, which must be tackled conscientiously to prevent long lasting damage to the environment. Technological solutions should be seen as part of the available options. In this monograph, the authors M. R. Katebi, M. A. Johnson and J. Wilkie seek to introduce a comprehensive technological framework to the particular measurement and control problems of wastewater processing plants. Of course the disposal of urban sewage is a long-standing process but past solutions have used options (disposal at sea) which are no longer acceptable. Thus to meet new effluent regulations it is necessary to develop a new technological paradigm based on process control methods, and this is what the authors attempt to provide.

Drinking water quality is a vast and complex subject. In addition to the topics already addressed in Volume 5, part B of this Handbook in 1995, this new volume discusses in an authoritative way the current key issues of drinking water quality and its control: - Toxicity tests for assessing drinking water quality - Toxicological approaches for developing drinking water standards - Analysis of organic micropollutants - Algal toxins and human health - Quality changes due to application of ozone and chlorine dioxide. The articles are written by leading experts and present the state of the art of drinking water research.
This volume will therefore be a valuable source not only for scientists and engineers, but also for decision-makers in government, environmental control and industry.

The Handbook of Environmental Chemistry provides the compilation of today's knowledge of processes in the natural environment and the behavior and impact of pollutants. It provides a valuable source for environmental managers, decision-makers, and scientists. Volume 5A is dedicated to water pollution.

The papers in this collection have originated from Britain, Eastern and Western Europe and India, with the delegates coming from fifteen countries, including a strong contingent from Japan. This indicates a widespread interest in the application of heat pumps. The heat pump suffers from an environmental dichotomy. On the one hand it saves fossil fuel energy, thereby reducing CO emissions. On the other hand, in the vapour compression form, 2 it generally employs CFCs which are destructive to our protective ozone layer as well as contributing to the greenhouse effect. Taking the first, heat pumps, perhaps have the widest application numerically in the heating (and cooling) of buildings and an excellent paper describes case studies concerning three large Norwegian hotels. In these, heat was pumped from the adjacent river or sea when heating was required, and during the summer, when cooling became necessary, to generate domestic hot water. The heat pumps were installed by SINTEF Refrigeration Engineering, Norway, and have demonstrated payback periods of about two years. The fractional total energy saving of the three hotels was 30% as a result, an impressive figure, indeed. A similar paper by a Belgian architectural consortium shows how this technique can be successfully applied to the cooling of a large television complex where considerable quantities of heat were being generated by the luminaries. In this exercise the cooling load was successfully pumped to provide hot water.

The Ebro is a typical Mediterranean river characterized by seasonal low flows and extreme flush effects, with important agricultural and industrial activity that has caused heavy contamination problems. This volume deals with soil-sediment-groundwater related issues in the Ebro river basin and summarizes the results generated within the European Union-funded project "AquaTerra." The following topics are highlighted: Hydrology and sediment transport and their alterations due to climate change, aquatic and riparian biodiversity in the Ebro watershed, occurrence and distribution of a wide range of priority and emerging contaminants, effects of chemical pollution on biota and integration of climate change scenarios with several aspects of the Ebro s hydrology and potential impacts of climate change on pollution.

The primary objective of the book is to lay the foundation for a better understanding of the behavior of environmental pollutants and their fluxes with respect to climate and land use changes."

This book is the edited proceedings of the Fifth International Conference on Finite Elements in Water Resources, held at the University of Vermont, USA in June 1984. This Conference cont inues the successful series started at Princeton University in 1976, followed by the Conference in Imperial College, London, UK in 1978, the third Conference at the University of Mississippi, USA in 1980 and the fourth at the University of Hannover, Germany in 1982. The objective of this Conference is to provide engineers and scientists interested in water resources with the state-of-t- art on finite element modelling. The Proceedings review the basic theory and applications of the technique in groundwater and seepage, transport phenomena, viscous flow, river, lake and ocean modelling. The fundamentals of the numerical techniques employed in finite elements are also discussed. Many applications illus trate the versatility and generality of the Finite Element Method for the simulation of a wide range of problems in water resources. More recent schemes, in particular, boundary elements, are also presented, together with a series of advanced numerical techniques. The Conference has become an internationally accepted forum for the presentation of new developments of finite elements in water resources techniques. Because of this, a large number of abstracts were submitted to the Organizing Committee and it is our only reg ret that it was impossible to accept all these contributions. The overwhelming response to our Call for Papers has ensured the high quality of these proceedings.

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary subject, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occuring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about one hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities ofwaste in relatively small and confined areas. Much of the chemical products and was te products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems."

Water scarcity and the need for ecological sustainability have led to the introduction of treated waste water as an additional water resource in the national water resource management plans of Mediterranean countries. Summarizing the results generated within the European Union-funded project "INNOVA-MED, "this volume highlights the following topics: Application of innovative technologies and practices for waste water treatment and reuse adapted to the Mediterranean regionConstraints on the application of advanced treatments and reuse of reclaimed water and sludgeProblems and requirements of sustainable water management in the Mediterranean area

The book includes several examples of Mediterranean countries, such as Tunisia, Morocco, Egypt, Palestine and Spain, and presents their practical experiences in the application of innovative processes and practices for waste water treatment and reuse. "

This book brings together environmental scientists and engineers to discuss the development of new approaches and methodologies which utilize microalgae for biological wastewater treatment. The researchers report their recent findings on microalgal removal of nutrients, heavy metals and other organic pollutants from sewage and industrial effluents. The technologies discussed here include biosorption and bioaccumulation of heavy metals, cell immobilization of algae, and mathematical modelling of metal uptake by cells. This book is unique in that it takes a practical approach to the subject matter and is a useful reference both in and outside of the laboratory.

Nonrenewable energy resources, comprising fossil fuels and uranium, are not ran domly distributed within the Earth's crust. They formed in response to a complex array of geologic controls, notably the genesis of the sedimentary rocks that host most commercial energy resources. It is this genetic relationship between economic re sources and environment that forms the basis for this book. Our grouping of petro leum, coal, uranium, and ground water may appear to be incongruous or artificial. But our basic premise is that these ostensibly disparate resources share common genetic attributes and that the sedimentological principles governing their natural distributions and influencing their recovery are fundamentally similar. Our combined careers have focused on these four resources, and our experiences in projects worldwide reveal that certain recurring geologic factors are important in controlling the distribution of com mercial accumulations and subsurface fluid flow. These critical factors include the shape and stability of the receiving basin, the major depositional elements and their internal detail, and the modifications during burial that are brought about in these sediments by pressure, circulating fluids, heating, and chemical reaction. Since the first edition of this book in 1983, there has been a quantum leap in the volume of literature devoted to genetic stratigraphy and refinement of sedimentologi cal principles and a commensurate increase in the application of these concepts to resource exploration and development."

Contamination of the aquatic environment by antifouling compounds has been a topic of increasing importance during the last few years. This book describes advances in antifouling paint biocides, and provides thorough evaluation of research and information on occurrence and levels, environmental fate, analytical techniques and methods for the monitoring and control, environmental modeling, ecotoxicological effects and risk assessment placing emphasis on the knowledge acquired over the last decade.

The main purpose of water quality monitoring may be seen as evaluating water quality conformity against water quality standards, especially for administrative purposes. Moreover, water quality monitoring data can be applied to estimate and evaluate pollutant loads in rivers. Chronological water quality fluctuations and vertical water quality profiles in water bodies are also important when taking into account the effects of land-based pollutants on coastal sea and estuary water quality. This book discusses the relationships between pollutant discharge and water quality, taking into account urban development and indicators like the pollutant load per capita flowing into the water body (PLCwb), an index used to evaluate the contribution of municipal wastewater pollutant discharge to pollutant loads flowing into ambient water bodies such as coastal zones, bays and lakes.

This volume is the proceedings of a symposium held on April 6-8, 1999, in San Francisco, CA, USA, and sponsored by the US Environmental Protection Agency's (EPA) Environmental Monitoring and Assessment Program (EMAP). EMAP is the primary program of the EPA's Office of Research and Development to advance the science of statistically-based ecosystem monitoring; and establish baseline conditions and trends of the nation's natural resources. The first volume in this series of EMAP-sponsored symposium proceedings addressed Monitoring Ecological Condition at Regional Scales' (1998). The current proceedings was the result of the EMAP Symposium on Western Ecological Systems' (1999), and presaged the new EMAP Western Pilot Study, which will include one third of the contiguous United States. The information found in these proceedings on the state of monitoring science, and existing monitoring programs undertaken by Federal and State agencies, academic institutions, tribal governments, and environmental protection interest groups helped to establish a starting point for embarking on the EMAP Western Pilot. This volume represents current scientific and management approaches, and the results of monitoring and assessment in the western US ecosystems. The chapter topics include regional assessments, approaches to database design, landscape considerations, water quality and land use, and focuses on watersheds, lakes and rivers, and marine coastal areas. Publication of these proceedings constitutes a sound starting point for the assessment of the ecological resources in the western US and will facilitate collaborative efforts in the development and application of sound approaches to monitoring and assessment of ecological resources in the US and abroad.
