Water risks and security are a major global hazard in the 21st century and it is essential that water professionals have a solid grounding in the principles of preventative risk management. This second edition of the key textbook, Risk Management for Water and Wastewater Utilities, extends beyond first principles and examines the practicalities of resilience and vulnerability assessment, strategic risk appraisal and the interconnectedness of water utility risks in a networked infrastructure. It provides an up-dated overview of tools and techniques for risk management in the context of the heightened expectations for sound risk governance that are being made of all water and wastewater utilities. Risk Management for Water and Wastewater Utilities provides a valuable starting point for newly appointed risk managers in the utility sector and offers MSc level self-paced study with self-assessment questions and abbreviated answers, key learning points, case studies and worked examples.

In a world where there is a growing awareness of the possible effects of human activities on climate change, there is a need to identify the emission of greenhouse gases (GHG) from wastewater treatment plants (WWTPs). As a result of this growing awareness, governments started to implement regulations that require water authorities to report their GHG emissions. With these developments there exists a strong need for adequate insight into the emissions of N2O and CH4. With this insight water authorities would be able to estimate and finally reduce their emissions. The overall objectives of the different research programs performed by partners of the GWRC members WERF (United States of America), WSAA (Australia), CIRSEE-Suez (France) and STOWA (the Netherlands) were: To define the origin of N2O emission. To understand the formation processes of N2O. To identify the level of CH4 emissions from wastewater collection and treatment systems. To evaluate the use of generic emission factors to estimate the emission of N2O from individual plants

Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously, meeting stricter and stricter regulations. Many control strategies have been proposed in the literature for improved and more efficient operation of wastewater treatment plants. Unfortunately, their evaluation and comparison - either practical or based on simulation - is difficult. This is partly due to the variability of the influent, to the complexity of the biological and biochemical phenomena and to the large range of time constants (from a few minutes to several days). The lack of standard evaluation criteria is also a tremendous disadvantage. To really enhance the acceptance of innovative control strategies, such an evaluation needs to be based on a rigorous methodology including a simulation model, plant layout, controllers, sensors, performance criteria and test procedures, i.e. a complete benchmarking protocol. This book is a Scientific and Technical Report produced by the IWA Task Group on Benchmarking of Control Strategies for Wastewater Treatment Plants. The goal of the Task Group includes developing models and simulation tools that encompass the most typical unit processes within a wastewater treatment system (primary treatment, activated sludge, sludge treatment, etc.), as well as tools that will enable the evaluation of long-term control strategies and monitoring tasks (i.e. automatic detection of sensor and process faults). Work on these extensions has been carried out by the Task Group during the past five years, and the main results are summarized in Benchmarking of Control Strategies for Wastewater Treatment Plants. Besides a description of the final version of the already well-known Benchmark Simulation Model no. 1 (BSM1), the book includes the Benchmark Simulation Model no. 1 Long-Term (BSM1_LT) - with focus on benchmarking of process monitoring tasks - and the plant-wide Benchmark Simulation Model no. 2 (BSM2).

London's sewers could be called the city's forgotten underground: mostly unseen subterranean spaces that are of absolutely vital importance, the capital's sewers nonetheless rarely get the same degree of attention as the Tube. Paul Dobraszczyk here outlines the fascinating history of London's sewers from the nineteenth century onwards, using a rich variety of colour illustrations, photographs and newspaper engravings to show their development from medieval spaces to the complex, citywide network, largely constructed in the 1860s, that is still in place today. This book explores London's sewers in history, fiction and film, including how they entice intrepid explorers into their depths, from the Victorian period to the present day.

Mathematical modelling of activated sludge systems is used widely for plant design, optimisation, training, controller design and research. The quality of simulation studies varies depending on the project objectives, finances and expertise available. Consideration has to be given to the model accuracy and the amount of time required carrying out a simulation study to produce the desired accuracy. Inconsistent approaches and insufficient documentation make quality assessment and comparison of simulation results difficult or almost impossible. A general framework for the application of activated sludge models is needed in order to overcome these obstacles. The genesis of the Good Modelling Practice (GMP) Task Group lies in a workshop held at the 4th IWA World Water Congress in Marrakech, Morocco where members of research groups active in wastewater treatment modelling came together to develop plans to synthesize the best practices of modellers from all over the world. The most cited protocols were included in the work, amongst others from: HSG (Hochschulgruppe), STOWA, BIOMATH and WERF. The goal of the group is to set up an internationally accepted framework to deal with the ASM type models in practice. This framework shall make modelling more straightforward and systematic to use especially for practitioners and consultants. Additionally, it shall help to define quality levels for simulation results, a procedure to assess this quality and to assist in the proper use of the models. The framework will describe a methodology for goal-oriented application of activated sludge models demonstrated by means of a concise guideline about the procedure of a simulation study and some illustrative case studies. The case studies shall give examples for the required data quality and quantity and the effort for calibration/validation with respect to a defined goal. The final report will include an extended appendix with additional information and details of methodologies. Additional features in Guidelines for Using Activated Sludge Models include a chapter on modelling industrial wastewater, an overview on the history, current practice and future of activated sludge modelling and several explanatory case studies. It can be used as an introductory book to learn about Good Modelling Practice (GMP) in activated sludge modelling and will be of special interest for process engineers who have no prior knowledge of modelling or for lecturers who need a textbook for their students. The STR can also be used as a modelling reference book and includes an extended appendix with additional information and details of methodologies. Scientific and Technical Report No. 22

As the world's population has increased, sources of clean water have decreased, shifting the focus toward pollution reduction and control. Disposal of wastes and wastewater without treatment is no longer an option. Fundamentals of Wastewater Treatment and Engineering introduces readers to the essential concepts of wastewater treatment, as well as the engineering design of unit processes for the sustainable treatment of municipal wastewater. Filling the need for a textbook focused on wastewater, it first covers history, current practices, emerging concerns, and pertinent regulations and then examines the basic principles of reaction kinetics, reactor design, and environmental microbiology, along with natural purification processes. The text also details the design of unit processes for primary, secondary, and advanced treatment as well as solids processing and removal. Using detailed calculations, it discusses energy production from wastewater. Comprehensive and accessible, the book addresses each design concept with the help of an underlying theory, followed by a mathematical model or formulation. Worked-out problems demonstrate how the mathematical formulations are applied in design. Throughout, the text incorporates recent advances in treatment technologies. Based on a course taught by the author for the past 18 years, the book is designed for undergraduate and graduate students who have some knowledge of environmental chemistry and fluid mechanics. Readers will get a strong grounding in the principles and learn how to design the unit processes used in municipal wastewater treatment operations. Professionals in the wastewater industry will also find this a handy reference.

In this concise, engaging, and provocative work, Richard Porter introduces readers to the economic tools that can be applied to problems involved in handling a diverse range of waste products from business and households. Emphasizing the impossibility of achieving a zero-risk environment, Porter focuses on the choices that apply in real world decisions about waste. Acknowledging that effective waste policy integrates knowledge from several disciplines, Porter focuses on the use of economic analysis to reveal the costs of different policies and therefore how much can be done to meet goals to protect human health and the environment. With abundant examples, he considers subjects such as landfills, incineration, and illegal disposal. He discusses the international trade in waste, the costs and benefits of recycling, and special topics such as hazardous materials, Superfund, and nuclear waste. While making clear his belief that not every form of waste presents the same amount of risk, Porter stresses the need for open-minded approaches to developing new policies. For students, policymakers, and general readers, he provides insight and accessibility to a subject that others might leave out-of-sight, out-of-mind, or buried under an impenetrable prose of statistics and jargon.

This companion to Accounting for Resources, 1 tracks the life cycle of specific elements, such as chlorine and heavy metals, in order to estimate the generation and dissipative losses of material wastes. The book begins with a succinct review of the life-cycle analysis methodology and evaluates some of its weaknesses in estimating the generation of waste. The authors propose a new quantitative measure of the potential for environmental harm of waste materials. They include case studies to add weight to their proposal. Four horizontal life-cycle case studies are included; one for chlorine and chlorine chemicals; one for mercury; one for arsenic and cadmium; and the other for copper, lead and zinc. The book also includes a longitudinal study of heavy metals use and dissipation, during the period 1880-1980 with reference to the Hudson-Raritan basin. The book concludes with an overview, including some recommendations for future research and for policy changes with respect to governmental statistical data collection and organization.

Every day throughout Britain, by road, by rail and by sea, there are large numbers of routine movements of radioactive cargo. Materials at all stages of the nuclear cycle, from uranium ore to nuclear waste, from nuclear warheads to radioactive isotopes used in medicine, are constantly on the move. In normal circumstances handling low-level material exposes workers to small doses of radiation, but a serious accident could lead to widespread contamination and to the major risk of additional deaths from cancer. The accident record is not good. There are repeated small accidents and many people believe that the major accident is simply waiting to happen. This book gives a thorough account of what is moved, by wham and far what purpose. It considers the risks, including that of terrorism, the safety record and the precautions. It also highlights the perils of the secrecy surrounding the industry: for example, local councils are responsible for coping with any accident, but are not told when or where nuclear movements are taking place. Martin Bond's careful work is a large step towards order in a chaotic industry. Originally published in 1992

Deliberately, accidentally, or consequentially, first responders and waste site workers handle unknown substances of varying degrees of danger every day. Unidentified chemicals involved with clandestine production of WMD agents or drugs, explosive materials, unlabeled waste, and forensic samples all pose a threat to the worker and those they protect. A straightforward, concise handbook of practical strategies is needed to perform effective risk assessment and management in the face of uncertainty. Written for emergency workers responsible for the safe response to and management of unknown hazardous materials, Emergency Characterization of Unknown Materials providesreadily applicable strategies for developing and implementing a fluid concept of risk analysis based on hazard characterization in emergency situations where definitive identification of the material may be impractical or even impossible. Using a hands-on approach involving the manipulation of small amounts of material, the author discusses strategies to identify threats and vulnerabilities, ascertain exposure, and reduce or eliminate impact. The book begins with an overview of chemical and physical terms and definitions. It continues with a look at types of hazards presented by chemical compounds and mixtures, organisms, and radiation sources. It covers approximately 63 portable technologies for field identification or characterization and examines general technological advantages and disadvantages relative to hazard identification. The final chapter presents strategies for use in identifying or characterizing suspected weapons of mass destruction, illegal drugs, explosive substances, biological hazards, and other hazardous materials. Each chapter includes extensive references and a comprehensive index. Providing a sweeping overview of hazards and emphasizing risk analysis and public safety, Emergency Characterization of Unknown Materials gives first responders an advantage they deserve.

Except in schoolboy jokes, the subject of human waste is rarely aired. We talk about water-related diseases when most are sanitation-related - in short, we don t mention the shit.A century and a half ago, a long, hot summer reduced the Thames flowing past the UK Houses of Parliament to a Great Stink, thereby inducing MPs to legislate sanitary reform. Today, another sanitary reformation is needed, one that manages to spread cheaper and simpler systems to people everywhere.In the byways of the developing world, much is quietly happening on the excretory frontier. In 2008, the International Year of Sanitation, the authors bring this awkward subject to a wider audience than the world of international filth usually commands. They seek the elimination of the Great Distaste so that people without political clout or economic muscle can claim their right to a dignified and hygienic place to go .Published with UNICEF

In addition to a solid introduction to combustion and burner fundamentals, an outstanding panel of contributing authors address all major burner types and explore a range of topics never before adequately covered in a handbook, including noise, burner controls, and physical modeling.

Little is known about the volume of international recycling in Asia, the problems caused and the struggle to properly manage the trade. This pathbreaking book addresses this gap in the literature, and provides a comprehensive overview of the international trade flow of recyclable waste in Asia and related issues. The expert contributors discuss the various types of recyclable waste that Asian countries import, and illustrate that there are consequently higher numbers of cheaper informal recyclers with lower pollution control costs than formal recyclers with more expensive but environmentally sound technologies. They explore how governments across China, Vietnam, South Korea and Japan are therefore struggling to minimize the negative impact from informal recycling via trade regulation of recyclable and hazardous waste and comprehensive cooperation mechanisms to promote efficient use of resources. Preventive measures against illegal and/or improper transboundary movement of hazardous waste in Asia are also analyzed. This unique and fascinating book aims to facilitate a common understanding of the issues caused by international recycling in Asia to encourage effective international and regional cooperation in order to establish a sound recycling system. As such, it will prove an invaluable resource to academics, researchers and students with an interest in Asian studies, economics, environmental studies, international economics and industrial economics.

The books currently available on this subject contain some elements of physical-chemical treatment of water and wastewater but fall short of giving comprehensive and authoritative coverage. They contain some equations that are not substantiated, offering empirical data based on assumptions that are therefore difficult to comprehend. This text brings together the information previously scattered in several books and adds the knowledge from the author's lectures on wastewater engineering.

Physical-Chemical Treatment of Water and Wastewater is not only descriptive but is also analytical in nature. The work covers the physical unit operations and unit processes utilized in the treatment of water and wastewater. Its organization is designed to match the major processes and its approach is mathematical. The authors stress the description and derivation of processes and process parameters in mathematical terms, which can then be generalized into diverse empirical situations. Each chapter includes design equations, definitions of symbols, a glossary of terms, and worked examples.

One author is an environmental engineer and a professor for over 12 years and the other has been in the practice of environmental engineering for more than 20 years. They offer a sound analytical mathematical foundation and description of processes.

FROM THE PREFACE
The main objective of composting is to transform organic materials into a stable usable product. Often organic materials which may have limited beneficial use in their raw state or have regulatory disposal constraints can be transformed by composting into marketable products. The limits on beneficial reuse may be regulations or they may be due to the potential for materials to be putrescible or pathogenic. Composting can be a solution for each of these.

The implementation of composting on a large scale (in contrast to home or backyard composting) involves materials handling. Technological implementation of composting must be consistent with the biological demand of the system. If the biological system is violated, conditions will not be optimized for composting, and problems such as odor generation, insufficient aeration or moisture, or a combination of these conditions may result. Past problems and closure of facilities have been largely due to violations of the biological systems. Product quality with respect to particle size, inclusions, moisture content and other physical aspects are a function of engineering design. A well designed system must have the biological and engineering principles in harmony at all times.
