Focuses on the application of membrane technologies in removing toxic metals\metalloids from water. Particular attention is devoted to the removal of arsenic, uranium, and fluoride. These compounds are all existing in the earth's crust at levels between two and five thousands micrograms per kg (parts per million) on average and these compounds can be considered highly toxic to humans, who are exposed to them primarily from air, food and water. In order to comply with the new maximum contaminant level, numerous studies have been undertaken to improve established treatments or to develop novel treatment technologies for removing toxic metals from contaminated surface and groundwater. Among the technologies available, applicable for water treatment, membrane technology has been identified as a promising technology to remove such toxic metals from water. The book describes both pressure driven (traditional processes, such as Nanofiltration, Reverse Osmosis, Ultrafiltration,etc) and more advanced membrane processes (such as forward osmosis, membrane distillation, and membrane bio-reactors) employed in the application of interest. Key aspect of this book is to provide information on both the basics of membrane technologies and on the results depending on the type of technology employed.

Part of Water Quality Set - Buy all four books and save over 30% on buying separately! Drinking Water Quality Management from Catchment to Consumer is a best practice book that builds on the experience of water suppliers and experts across the world in order to provide a practical guide to help utilities improve the management of drinking water quality. It is based on the Water Safety Plan approach and the principles of the Bonn Charter for Safe Drinking Water, and is intended to complement and support other relevant publications particularly the WHO Water Safety Plan Manual. It has evolved from the work of The Bonn Network which is a global group of water suppliers originally established to develop and share best practice in drinking water quality management based on the Bonn Charter. The emphasis is on practical information "by operators for operators", learning from the experience of a range of water suppliers across the world. The book supports and encourages users to think through the best way for them to improve drinking water quality management taking account of local factors. It recognises that whilst water suppliers are central to the provision of good drinking water, this has to take place within a broader legal, institutional, and financial framework which is the responsibility of Government and others. It thus highlights the ways that water suppliers can work with a range of partners to ensure that all are committed to the same goal of good safe drinking water. Drinking Water Quality Management from Catchment to Consumer is an essential reference for water quality, laboratory and operational managers from water utilities around the world. It is also helpful to consultants working in this area and regulatory, health and municipal, and catchment management authorities. The book is of interest to academics working in the field of drinking water quality, and risk management and may be used on any courses aimed at managing drinking water quality.

This book provides an ecosystem perspective in addressing the water resource management issues in the South Asian region. It argues that aspects such as sources of water, its distribution and users; land--water interrelations; drivers of change such as laws, policies and institutions; management of issues and technologies related to water supply; institutional set-up; economic instruments such as pricing, taxes, subsidies; and economics of ecosystem services are crucial. Climate changes, melting of glaciers and polar ice caps, rising sea level and the increased frequency of extreme events, have to be factored into integrated management of water resources. This book addresses some of these major issues related to aquatic ecosystems and focuses on three major aspects: (a) concepts related to ecosystems, ecosystem services and their linkages with water; (b) human impacts on ecosystems, particularly the aquatic ecosystems, and their assessment; and (c) the management, including policy, governance and economics. Comprising new theories, research and case studies, the book will be useful those concerned with water resource management -- professionals, students and researchers.

Water quality processes in the drinking water distribution network are strongly influenced by the flow velocity and residence time of the water in the network. In order to understand how the water quality changes in the drinking water distribution network, a good understanding of hydraulics is required. Specifically in the periphery of the network, where customers are connected, the hydraulics can change rapidly. During the night time the water is almost stagnant and the residence time increases. In the morning, when everybody gets up and flushes the toilet and takes a shower, high flow velocities can occur. During the remainder of the day flow velocities are low. The stochastic endues model SIMDEUM was developed to simulate water use on a small time scale (1 s) and small spatial scale (per fixture). SIMDEUM enables a good model of flow velocities, residence times and the connected water quality processes in the water distribution network. Stochastic Water Demand Modelling: Hydraulics in Water Distribution Networks describes the requirements of hydraulics in water quality modelling and provides insight into the development of detailed residential and non-residential water demand models. The book illustrates the use of detailed demand models in water quality models with respect to the variation in residence times and the relation with particle accumulation and resuspension. The models are compared to measurements in several real drinking water distribution networks.

Aerobic Wastewater Treatment Processes: History and Development discusses the widely differing influences on the development of aerobic treatment such as water supply, toxic trade effluents, microscopy and population growth in urban areas. It covers the historical development of sewage treatment and the emergence of aerobic biological treatment from the early nineteenth century to the present day. The importance of water supply and the influence this had on the water-carriage system is examined, as is the consequent discharge of sewage into rivers. The factors which govern process selection and process development are discussed. There is a continued impetus to reduce land area, capital costs, running costs, and to optimise performance and process control. The discovery of the activated sludge process is detailed including the development, in the early 1900s, of many forms of this process. Industrial wastes were discharged to biological treatment systems and the impact of such pollutants is reviewed. The work of Royal Commissions, River Boards and the National Rivers Authority is summarised, and the advances in chemical analysis and "on-line" measurement of chemical quality characteristics. Later developments such as reed beds and the use of hybrid treatment systems are covered. Examples are included such as the "fixed film" activated sludge process which has found application for small communities in package form, and also for large-scale municipal treatment plants. Aerobic Wastewater Treatment Processes: History and Development is valuable reading for students of the following courses on CIWEM Dip examination, WITA and B Tech and Environmental Science and Civil Engineering.

The Economics of Industrial Water Use presents an authoritative collection of the most important articles to have applied economic models and measurement techniques to the topic of industrial water use over the last thirty years. It includes an original introductory chapter which summarizes and critically assesses the literature on this important subject. These papers employ a range of modelling approaches including econometric estimation, linear programming, input-output models, non-market valuation and integrated river basin planning models. They also provide empirical evidence of the significant role played by economic forces in determining industrial water intake, discharge and recirculation. This comprehensive volume will be an indispensable reference source for those with an interest in water's role in industrial applications.

This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

The Water Environment Research Foundation (WERF) Nutrient Challenge Research Program and the Water Environment Federation (WEF) cooperated in a comprehensive study of nutrient removal plants designed and operated to meet very low levels of effluent N and P. Both existing and new technologies are being adapted to meet requirements that are as low as 3 mg/L TN and 0.1 mg/L TP, and there is a need to define their capabilities and reliabilities in the real world situation of wastewater treatment plants. This effort focused on maximizing what can be learned from existing technologies in order to provide a database that will inform key decision makers about proper choices for both technologies and rationale bases for statistical permit writing. To this end, managers of 22 plants, 10 achieving low effluent TP, 9 achieving low effluent TN, and 3 achieving low effluent ammonia, were asked to provide 3 years of operational data that were analyzed using a consistent statistical approach. Technical papers were compiled for each plant including a summary of influent loading, process design and operating conditions, unusual events, upsets and anecdotes related to process operation, and the statistical summary of final effluent data that considered both process reliability and the permit limits applied. The first year of this effort culminated in a workshop held in Chicago at WEFTEC 2008 and the second year in a workshop held in Orlando at WEFTEC 2009. Technological conclusions that can be drawn from the study in terms of what can be learned by comparing the different nutrient removal processes employed at these 22 plants and several additional BNR facilities in Florida are described in joint manuscripts submitted by Parker et al (2009) and Bott et al (2009). In a parallel effort using the data and conclusions generated from this study, Neethling et al (2009) proposed a set of quantitative descriptors that attempt to define the nutrient removal performance in terms of effluent quality percentile statistics referred to as Technology Performance Statistics (TPSs). The TPSs were defined as three separate values representing the lowest, median, and reliably achievable performance (Neethling et al, 2009).

With the recent advent of improved analytical and biomarker detection capabilities, a variety of organic chemicals have been found in trace amounts (Trace Organic Chemicals, TOrCs) in surface waters and fish tissue. TOrCs include pharmaceuticals, personal care products, surfactants, pesticides, flame retardants, and other organic chemicals, some with unknown modes of action or effects. Identifying or predicting ecological effects of TOrCs in typical aquatic multi-stressor situations is challenging, requiring a variety of epidemiological tools that together, can diagnose effects at multiple scales of ecological organization. Five objectives were addressed in this research: (1) develop and apply a procedure to prioritize which TOrCs are of most concern; (2) develop and test a conceptual site screening framework; (3) evaluate and test diagnostic approaches to identify potential risks due to TOrCs using various case studies; (4) develop a relational database and user interface with which the water resource community can enter, store, and search TOrC exposure data in the U.S.; and (5) foster partnerships and transfer knowledge gained in this research to the water quality community. TOrC fate, effects, and occurrence data were compiled in a database for over 500 organic chemicals based on over 100 published studies representing more than 50 organizations and 700 sites. Alternative risk-based prioritization processes and draft lists of high priority TOrCs were developed. A preliminary site screening and diagnostic framework was developed and evaluated using seven different case study sites. EPA's causal analysis (stressor identification) procedures, Canada's Environmental Effects Monitoring (EEM) procedure, the ecosystem model CASM (Comprehensive Aquatic System Model), and several other specialized diagnostic tools were used and evaluated. A relational database based on Tetra Tech's EDAS2 was developed using the Microsoft platform. The modified version of EDAS2, built on the EPA WQX data model, provides web-based data queries using a combination of tabular data for downloads and a visual map interface that allows the user to view, query, and select sites from the map having chemical or biological data. The database is not discussed in this report but can be accessed through WERF. This Final Report summarizes all other approaches used and results obtained in this research, discusses critical data gaps and other important uncertainties, and provides testable hypotheses and recommendations for Phase 2 testing and analyses.

The absence of water supply infrastructure is a critical issue that affects the sustainability of cities in the developing world and the quality of life of millions of people living in these cities. Urban India has probably the largest concentration of people in the world lacking safe access to these infrastructures. This book is a unique study of the politics of water supply infrastructures in three metropolitan cities in contemporary India - Bangalore, Chennai and Kochi. It examines the process of change in water supply infrastructure initiated by notable Public Private Partnership's efforts in these three cities to reveal the complexity of state-society relations in India at multiple levels - at the state, city and neighbourhood levels. Using a comparative methodology, the book develops as understanding of the changes in the production of reform water policy in contemporary India and its reception at the sub-national (state) level. It goes on to examine the governance of regimes of water supply in Bangalore, Chennai and Kochi, and evaluates the role of the partnerships in reforming water supply. The book is a useful contribution to studies on Urban Development and South Asian Politics.

Utility performance, especially in developing countries is still working toward the standard necessary to deliver best practice. Utility Benchmarking and Regulation in Developing Countries examines performance monitoring and regulation as a prominent efficiency enhancement tool and clarifies many of the unknowns regarding the design and approach surrounding the area of utility management. Principles and practices are linked in a way that is informative and accessible, highlighting the challenges facing those who are trying to improve performance in the water sector. Operational settings are complex and unpredictable in developing countries due to inadequate infrastructure planning and this book makes clear which systems work best in these situations. Utility Benchmarking and Regulation in Developing Countries discusses performance monitoring in the critical areas of utility management that achieve sustainable performance goals: Performance development planning Modes of performance monitoring Provocative approaches to incentives creation Monitoring through high incentive plans Customer relations monitoring Pro-poor oriented monitoring Careful use of partial performance indicators Proposed indicators for assessing governance incentives A case study on the National Water and Sewerage Corporation, Uganda is included in the book detailing the difficulties in discerning performance progress based on partial performance indicators. It underlines disparities in basing performance conclusions on partial performance indicators on one hand and aggregate analysis using modern benchmarking toolkits on the other. This is an excellent handbook for utility monitors or regulators whose primary duty is to oversee performance management. It is a valuable resource for decision-makers, analysts, and policy-makers and can be used in capacity-building programs (both in-house and in universities) around the world.

Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save a total GBP119! Safe drinking water is a basic need for all human beings. Preventing microbial contamination of drinking water is of primary concern since endemic illness and outbreaks of infectious diseases can have significant social and economic consequences. Confirming absence of indicators of faecal contamination by water analysis only provides a limited verification of safety. By measuring pathogenic organisms in source water and modelling their reduction by treatment, a higher level of drinking water safety can be verified. This book provides stochastic methods to determine reduction of pathogenic microorganisms by drinking water treatment. These can be used to assess the level and variability of drinking water safety while taking uncertainty into account. The results can support decisions by risk managers about treatment design, operation, monitoring, and adaptation. Examples illustrate how the methods can be used in water safety plans to improve and secure production of safe drinking water.

Increasing global pressure on water resources requires many actions from governments and individuals to achieve sustainable levels of water use. These involve management tasks such as project development and utility operation, but the degree of interdependence among the many participants in water management is so great that additional regulatory and coordination mechanisms are needed to control water development and uses. This book is designed to be the introductory work in the new Governance and Management for Sustainable Water Systems Series. It introduces the subject of governance of water systems and illuminates relatively unexplored topics of water resources management.The material is practical but advanced in the sense that theories of industry organization, governance, and institutional analysis are applied in new ways. New case study applications are provided in the book and help the reader to understand how their disciplines apply to water management. The case studies are drawn from each sector and region in the world, including cases from the U.S.A., Europe, the Middle East, South America and a global case to cover water system privatization.

Resources end up in wastewater through inefficient consumption. As a result, wastewater contains reusable water, carbon (energy) and nutrients (nitrogen, phosphorus and sulfur) that could be recovered or reused. Meanwhile, current treatment objectives are to produce an acceptable quality of water for reuse or discharge at the lowest life cycle cost. Most of the current treatment processes manage carbon and nutrients as wastes to be removed, and do not attempt to capitalize on these resources inherent in wastewater. In the context of sustainability and climate change, the next generation of wastewater treatment processes should focus on resource recovery (water reuse, energy/carbon recovery and nutrient recovery) as much as they currently do on treatment. The future goal is for wastewater treatment of domestic wastewater to have a minimal carbon footprint, and to be 100% self-sustainable with regards to energy, carbon, and nutrients, while achieving a discharge or reuse quality that preserves the quality of the receiving waters. In May 2009, the Water Environment Research Foundation (WERF) convened a work group of international experts in the wastewater sector to develop a Wastewater Treatment Technology Roadmap which will identify possible routes to sustainable wastewater treatment in a carbon-constrained world. The resultant Technology Roadmap report identifies pathways toward sustainable wastewater systems over the next few decades, including various approaches the sector could utilize over the 20-30 year planning horizon. The Technology Roadmap describes the current status of wastewater technologies, projects future treatment quality requirements, identifies research needs, and summarizes ongoing activities to meet the perceived future objectives such as reducing the carbon footprint while achieving lower nutrient levels. Work group participants brainstormed possible technology concepts which can be reasonably expected to produce actionable results that can be implemented by interested wastewater utilities. The participants considered typical and atypical approaches to optimizing carbon and nutrient management at WWTPs. Typical approaches include the evaluation of process modeling opportunities and constraints, and incremental resource and carbon management optimization techniques. Atypical approaches will be even more important to the future of wastewater resource reclamation. As an additional outcome, several work group members suggested conceptual and sustainable "plant of the future" treatment systems not constrained by existing infrastructure. Participants discussed their "Plant of the Future" concepts which can be expected to generate opportunities and research needs related to energy sources within treatment plants, changing wastewater characteristics, decentralized treatment, increased nutrient recovery and management, and total water reuse.

This project convened a team of experts in the fields of environmental engineering (AECOM), analytical chemistry and hydrogeology (USGS), and biological assay analysis (UA) to evaluate the occurrence and fate of estrogenic compound, and the estrogenicity of biosolids derived from wastewater treatment. Sludge and biosolids samples were collected through the solids treatment train of four wastewater treatment plants (WWTPs) operating a range of solids processing, treatment and disposal options that are typical to facilities across the United States. Targeted solids processing methods included thickening via gravity, gravity belt, and dissolved air flotation; stabilization via lime addition, aerobic digestion and anaerobic digestion; chemical conditioning; dewatering via centrifuge; and other processes including composting and pelletization. Targeted disposal options included beneficial reuse or disposal including land application, dedicated land disposal and landfilling. Samples were collected from the study plants between two and five times over two years, allowing for an assessment of seasonal variation. In some cases, sampling density was not sufficient to assess seasonal variations, but for certain compounds interesting seasonal trends were observed. The solids samples were supplemented by liquid samples at key locations in the study plants during several sample collection events. Over the course of the study 15 sample trips were conducted and a total of 90 samples were collected from the four study plants. For each sample collected, chemical analysis for steroid hormones and in vitro biological assay (bioassay) measurements were conducted to quantify estrogen receptor agonists, antagonists, and estrogenic activity. In addition to the estrogenic compounds, samples were analyzed for a suite of trace organic compounds (TOrCs), including anthropogenic wastewater indicators (AWIs) and pharmaceuticals, resulting in analysis for over 100 chemical compounds in each liquid or solid sample. Collection of these data substantially expanded the scope and value of the study, providing a more comprehensive evaluation of the effects of solids processing and treatment on TOrCs. Loads of TOrCs and estrogenic activity were calculated for each sample point based on flows and solids loadings data from the study plants. In this exercise, TOrC concentrations are multiplied by the solids loading (tons per day) to calculate the daily load of each compound in grams per day (g/day). This report provides comparisons of the chemical and biological assays used in this study, the results of select TOrC mass balances as well as a discussion of the results and areas for future research.

The Zambezi river is the fourth longest in Africa, crossing or bordering Zambia, Angola, Namibia, Botswana, Zimbabwe and Mozambique. The river basin is widely recognised as one of the most important basins in southern Africa and is the focus of contested development, including water for hydropower and for agriculture and the environment. This book provides a thorough review of water and sustainable development in the Zambezi, in order to identify critical issues and propose constructive ways forward. The book first reviews the availability and use of water resources in the basin, outlines the basin's economic potential and highlights key concerns related to climate vulnerability and risk. Focus is then devoted to hydropower and the water-energy-food (WEF) nexus, sustainable agricultural water management, and threats and opportunities related to provision of ecosystem services. The impact of urbanisation and water quality is also examined, as well as ways to enhance transboundary water cooperation. Last, the book assesses the level of water security in the basin, and provides suggestions for achieving Sustainable Development Goal (SDG) 6. Throughout, emphasis is placed on entry points for basin-level management to foster improved paths forward.

About 4000 medical compounds are being used in the drugs applied today. It is estimated that worldwide consumption of active compounds amounts to some 100 000 tons or more per year. Consequently, there is a need to highlight the most important questions and issues related to presence of pharmaceuticals in the environment. Pharmaceuticals in the Environment: current knowledge and need assessment to reduce presence and impact brings together results of previous and on-going EU projects with published data from both governmental sources and scientific literature and manufacturers' data on production and usage of pharmaceuticals. This book puts together the current knowledge and emphasises questions that deserve attention such as: * What is the spectrum of most relevant pharmaceutical products (PP's) for the aquatic environment? Which indicators for supporting environmental managers, health authorities? * What is the efficiency of urban and industrial sewage treatment plants over a year? What is the fate and behaviour of PP's in sewage treatment plants? If receiving waters are used for potable water supplies, does the presence of these compounds represent a potential hazard to human health? * Could we solve some problems by environmental or cleaner technologies? * What regulatory approaches, incentives, prevention actions can be implemented in order to lower PP's concentration in the environment? Does a European practical guidance can be developed? * Can the impacts of PPs on the environment be reduced through the use of eco-pharmaco-stewardship approaches including the use of clean synthesis, classification and labelling, and better communication of methods of 'good practice'? * How can we better monitor the environmental impact of a pharmaceutical once it has received a marketing authorisation?

Advanced Tools and Models to Improve River Basin Management in Europe in the Context of Climate Change - AquaTerra has developed from an integrated project of the 6th EU RTD Framework Programme that aims to provide the scientific basis for an improved river basin management through a better understanding of the river-sediment-soil-groundwater system as a whole, by integrating both natural and socio-economics aspects at different temporal and spatial scales. This book aims: * to provide better understanding of the river-sediment-soil-groundwater system at various temporal and spatial scales * to relate expected climate alterations to changes in deposition, mobility and distribution of pollutants in European river basins. * to provide the scientific basis for improved river basin management * to introduce novel tools for water and soil quality monitoring * to show the necessity of integrated modelling frameworks for impact evaluation of pollution as well as climate and land-use changes for definition of long-term management schemes The work illustrates the dynamic behavior of the pathway of pollutants in soils, groundwater, surface water and sediments. It highlights the fundamental importance of integrating knowledge from sereral combineddisciplines on various environmental compartments in order to understand the large number of processes that govern pollutant input, transport and turnover. Results shows that a significant step forward has been made in the development new analytical methods and of process-based numerical models that are capable of making predictions of likely trends and environmental changes to be expected in the near or distant future at the basin-scale. These models can be used e.g. to generate hydrologic scenarios based on climate models and to simulate pollutant distribution and turnover rates from decades to millennia.
