Industry and commerce use vast amounts of water and in some parts
of the world water is becoming a scarce commodity. We need to take
more care in our future use of water, and this book is a 'best
practice' manual for industrial and commercial users world-wide. It
offers a practical account of the measures which can be taken to
re-educate industrial and commercial users in the techniques of
water saving and re-use anywhere in the world. The principles are
covered in detail and supported by examples from specific
industries and commercial operations. Author Mohan Seneviratne is
Manager of Sydney Water's 'Every Drop Counts Business Program',
which won the prestigious 2006 Stockholm Industry Water Award in
recognition of how the utility is working in partnership with
business, industry and government to help ensure the long-term
sustainability of Sydney s water supply.
In this volume, the third in a set specifically written for the
industrial process and chemical engineer, the authors provide the
detailed information on filtration equipment and media which allows
the reader to then consider the pre-treatment of suspensions,
selection of the most appropriate equipment for the task, data
analysis and the subsequent design of the processes involved for
particular separations.
There is increasing political and environmental pressure on industry to clean up the water which it uses in many processes, and to re-use this water where possible. This cleaning is done using specially-developed industrial membranes and this book covers the types and design of membranes, how they work and in which industries they are used. Special attention is paid to the textile, food/ beverage, pharmaceutical, oil and pulp and paper industries where such membranes are in regular use.
Industrial desalination of sea and brackish water is becoming an
essential part in providing sustainable sources of fresh water for
a larger number of communities around the world. Desalination is a
main source of fresh water in the Gulf countries, a number of the
Caribbean and Mediterranean Islands, and several municipalities in
a large number of countries. As the industry expands there is a
pressing need to have a clear and well-written textbook that
focuses on desalination fundamentals and other industrial aspects.
This book will explore our forests as the most readily available and renewable source of carbon as well as the building block of chemicals, plastics, and pharmaceuticals as the next 100 years gradually push consumers toward alternate sources of chemicals. Meeting these needs from trees requires that new chemistry be developed so that plant materials is converted to commodity chemicals. This focused discussion on ongoing global efforts at creativity using forest and biomass based renewable materials will include six different mechanisms for bringing about change on this very innovative topic.
The sea is steadily rising, presently at 3.4 mm per year, and it is already costing billions in Venice, on the Thames river and in New York City, to counter sea-level-related surges. Experts anticipate an accelerated rise, and credible predictions for sea-level rise by the year 2100 range from 12 inches to above six feet. Study of the Earth's geologic history, through ice-core samples, links sea-level rise to temperature rise. Since the lifetime of carbon dioxide in the atmosphere is measured in centuries, and it has upset the balance of incoming and outgoing energy, the Earth's temperature will continue to rise, even if carbon burning ceases. Engineering the Earth's solar input appears increasingly attractive and practical as a means to lower the Earth's temperature and, thus, to lower the sea level. The cost of engineering the climate appears small; comparable, even, to the already-incurred costs of sea-level rise represented by civil engineering projects in London, Venice and New York City. Feasible deployment of geoengineering, accompanied by some reduction in carbon burning, is predicted to lower the sea level by the order of one foot by 2100, which negates the expected rise and would provide an immense economic benefit. The accompanying lower global temperature would reduce the severity of extreme weather and restore habitability to lethally hot parts of the world.
This work delivers ideas, comments and projects on energy,
communications, transport, management, human resources, and
financial and legal issues which macroengineering can contribute
towards the solution of the Earth's environmental problems. Some 20
engineers and scholars identify problems in the next century whose
solutions call for international policy planning and a more
collaborative, peaceful and prosperous world order.
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.
For more than a century, national and international governing bodies have had some involvement in regulating the quality and safety of food during production and delivery. Since the beginnings of this "modern" food regulation in the early 20th century, the way that food is produced, packaged and distributed has changed drastically. It is difficult to determine if technological advances in the areas of polymer science, refrigeration, and transportation have driven the globalization of the food supply or if the food industry has drawn from these technologies to satisfy consumer's desire and need. Ensuring the safety of food requires a complex and ever-changing set of interactions between producers, distributors, consumers and regulators. As advances are made in packaging and food additives, as food distributions systems evolve to meet consumer needs, or as these respond to environmental and population changes, adjustments to regulatory systems may become necessary. Analytical, environmental and materials chemistry can often play important roles in responding to these changes and in continuing to help with the improvement of food safety and security. These five co-editors bring their respective expertise to the subject of the food system and the chemical advancements behind it.
Appreciating that coastal areas are under threat from misuse and overuse worldwide, this book reviews the need for marine conservation, summarizes general measures for ocean and coastal conservation, and explains the rationale for establishing marine protected areas. The second half of the book is a guideline for designing and implementing protected areas in order to make them viable and long-lasting in their effectiveness.
'Seawater' has been substantially updated in this second edition to take account of recent developments in marine science. Sections dealing with difficult physical and chemical concepts have been developed on the basis of feedback from the first edition, making this an ideal learning tool for oceanography students. Chapter 1 summarizes the special properties of water and the
role of the oceans in the hydraulic cycle. The distribution of
temperature and salinity in the oceans and how they influence water
density and movements is then discussed. Light and sound in
seawater are considered next, along with some uses of acoustics.
These are followed by an examination of the composition and
behaviour of dissolved constituents, including such topics as
residence times, the control of pH, and redox relationships.
This book collects papers from meetings of the American Chemical Society held over the past four years, reporting on trends in research for safe, efficient, biologically active agrochemicals. After an overview chapter, a section describes efforts in the discovery of new herbicides. A second section
The question of what environmental statistics is about is particularly important when it comes to the formulation of relevant research and training, whether in academia, agencies, or industries. This volume aims to give a new perception on the subject with some examples that are of concern and interest today. Environmental statistics is in a take-off stage both for reasons of societal challenge and statistical opportunity, and is demanding more and more from non-traditional and innovative statistical approaches. The chapters in this volume, which are specially prepared by several outstanding professionals involved in statistics and the environment, discuss the current state of the art in diverse areas of environmental statistics. The volume provides new perspectives and problems for future research, training, policy and regulation. It will be valuable to researchers, teachers, consultants and graduate students in statistics, environmental statistics, statistical ecology, and quantitative environmental sciences in academia, industries, governmental agencies, laboratories and libraries.
We are becoming increasingly aware of the overwhelming pollution of our limited water resources on this planet. And while many contaminants originate from Mother Earth, most water pollution comes as a direct result of anthropogenic activities. This problem has become so immense that it threatens the future of all humanity. If effective measures to reduce and/or remediate water pollution and its sources are not found, it is estimated by UN that 2.7 billion people will face water shortage by 2025 as opposed to 1.2 billion people who do not have access to clean drinking water now. Therefore, development of novel green technologies to address this major problem represents a priority of the highest importance. This book discusses green chemistry and other novel solutions to the water pollution problems which includes some interesting applications of nanoparticles. Novel Solutions to Water Pollution is a useful and informative text for those engaged in issues of water quality and water pollution remediation at operational, administrative, academic, or regulatory levels.
This book addresses one of the most challenging problems that plagues the environmental field today-subsurface contamination. The past three decades have ushered in various methods for removal of organic and inorganic contaminants from the subsurface to varying degrees of effectiveness. Because of the site-to-site variability in the nature of contamination characteristics, the pattern of waste disposal and accidental releases, the site characteristics and thus contaminant behavior, and hydrologic conditions, predicting the effectiveness of one treatment method over another is a daunting task. Field demonstration of innovative technologies is a key step in their development, however, only after successful scale-up from laboratory testing. This book features chapters written by researchers who have linked laboratory- and field-scales in efforts to find creative, cost-effective methods for prediction of successful remediation of contaminated soil and ground water. State-of-the-art technologies using physicochemical removal methods and biological methods are discussed in the context of not only their effectiveness in remediating organic and inorganic wastes from various subsurface environments but also in terms of useful flask-scale methods for measuring and predicting their field-scale effectiveness. Chapters address sorption and hydrolysis of pesticides by organoclays, use of Fentons agents to destroy chlorinated solvents removed from the subsurface by granulated activated carbon, methanol flushing as a means of removing toxaphene from soils, natural attenuation as a method for effectiveness of remediation metals and biodegrading acid-mine drainage constituents, and biodegradation ofradiologically contaminated soils. Also addressed in this book are current and future methods of assessing microbiological activity potential and diversity and of modeling biodegradation, contaminant flux, and gaseous transport in the subsurface.
This book outlines a simple and easy-to-follow process for auditing building operation to identify and reduce energy consumption. It explains the operational and cost-based opportunities, assessing the current conditions, analyzing the opportunities, and reporting the findings and documenting the plan. The book discusses the different building components and systems and how they affect energy efficiency and describes the operational energy efficiencies that can be gained by implementing no cost changes or alternate maintenance activities already funded. Capital improvement opportunities, and evaluating Return on Investment and life cycle replacement of equipment are also covered.

The volume will appeal to scholars and students of economics and political science.
Chemometrics and Chemoinformatics gives chemists and other scientists an introduction to the field of chemometrics and chemoinformatics. Chemometrics is an approach to analytical chemistry based on the idea of indirect observation. Measurements related to the chemical composition of a substance are taken, and the value of a property of interest is inferred from them through some mathematical relation. Basically, chemometrics is a process. Measurements are made, data is collected, and information is obtained to periodically assess and acquire knowledge. This, in turn, has led to a new approach for solving scientific problems: (1) measure a phenomenon or process using chemical instrumentation that generates data inexpensively, (2) analyze the multivariate data, (3) iterate if necessary, (4) create and test the model, and (5) develop fundamental multivariate understanding of the process. Chemoinformatics is a subfield of chemometrics, which encompasses the analysis, visualization, and use of chemical structural information as a surrogate variable for other data or information. The boundaries of chemoinformatics have not yet been defined. Only recently has this term been coined. Chemoinformatics takes advantage of techniques from many disciplines such as molecular modeling, chemical information, and computational chemistry. The reason for the interest in chemoinformatics is the development of experimental techniques such as combinatorial chemistry and high-throughput screening, which require a chemist to analyze unprecedented volumes of data. Access to appropriate algorithms is crucial if such experimental techniques are to be effectively exploited for discovery. Many chemists want to use chemoinformatic methods in their work but lack the knowledge required to decide which techniques are the most appropriate.
Forestry Economics introduces students and practitioners to all aspects of the management and economics of forestry. The book adopts the approach of managerial economics textbooks and applies this to the unique processes and problems faced by managers of forests. While most forestry economics books are written by economists for future economists, what many future forest and natural resource managers need is to understand what economic information is and how to use it to make better business and management decisions. John E. Wagner draws on his twenty years of experience teaching and working in the field of forest resource economics to present students with an accessible understanding of the unique production processes and problems faced by forest and other natural resource managers. There are three unique features of this book: The first is its organization. The material is organized around two common economic models used in forest and natural resources management decision making. The second is the use of case studies from various disciplines: Outdoor and Commercial Recreation, Wood Products Engineering, Forest Products, and Forestry. The purpose of these case studies is to provide students with applications of the concepts being discussed within the text. The third is revisiting the question of how to use economic information to make better business decisions at the end of each chapter. This ties each chapter to the preceding ones and reinforces the hypothesis that a solid working knowledge of these economic models and the information they contain are necessary for making better business decisions. This textbook is an invaluable source of clear and accessible information on forestry economics and management for not only economics students, but for students of other disciplines and those already working in forestry and natural resources.
New institutions don't come into being by themselves: They have to be organized. On the basis of research from a decade-long, multi-site study of efforts to transform freshwater management in Brazil, Practical Authority asks how new institutional arrangements established by law become operational in practice. The book explores how this happens by putting both agency and structures in motion. It looks at what actors in complex policy environments actually do to get new institutions off the ground. New configurations of authority in a policy area very often have to be produced relationally, on the ground, in practice. New organizations have to acquire problem-solving capabilities and recognition from others, what the authors call "practical authority." The story told here has a multiplicity of protagonists, many of whom are normally invisible in political studies, such as the state officials and university professors who struggled to move water reform forward. The book explores the interaction between their efforts to influence the design and passage of new legislation and the hard labor of creating the new water management organizations the laws called for. It follows three decades of law making at the national and state level and examines the creation of sixteen river basin committees throughout the country. By bringing together state and society actors around territorially specific problems, these committees were expected to promote a new vision of integrated water management. But none of the ones examined here followed the trajectory their organizers expected. Some adapted creatively to challenges, circumventing roadblocks encountered along the way; others never got off the ground. Rather than explain these differences on the basis of the varying conditions actors faced, the authors propose a focus on the process, and practice, of institution building.
The book "Green Technologies for the Environment" brings together experts in the field of biotechnology, chemistry, chemical engineering, environmental engineering and toxicology from both academia and industry, to discuss green processes for the environment. The topics included finding replacements for crude oil to meet both our energy needs as well as the supply of chemicals for the production of essential products, advances in chemical processing, waste valorization, alternative solvents, and developments in homogeneous and heterogeneous catalysis as well as enzyme-based processes for chemical transformations. Advances in green chemistry concepts will further enhance the field through the design of new chemicals and solvents. In addition, obtaining a better understanding of the mechanistic pathways involved in various reactions is essential toward advances in the field. The goal of the work described in each of the chapters is to address the need for best practices for chemical processes and for the production of chemicals, while promoting sustainability.
Climate change is a major challenge facing modern society. The chemistry of air and its influence on the climate system forms the main focus of this book. Vol. 2 of Chemistry of the Climate System takes a problem-based approach to presenting global atmospheric processes, evaluating the effects of changing air compositions as well as possibilities for interference with these processes through the use of chemistry.
