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.
Advances in Hydrology and Climate Change: Historical Trends and New Approaches in Water Resources Management highlights recent trends in the water sector that employ a variety of different innovative management and conservation approaches. The volume provides an informative overview of the issues and challenges in water resources affected by climate change conditions, such as drought, flooding, glacier changes, and overbuilt-up urban areas. Focusing on surface and groundwater related issues and sustainable solutions, the chapters present a variety of methods, including morphometric assessment, parameter estimation, long-term trend analysis, sustainability indexes, storm water management models (SWMM), entropy-based measurement of long-term precipitation, etc. The volume focuses on providing a better understanding of climatic uncertainty through hydrometeorological data sets and their application in hydrological modeling. These analyses help to serve as the basis for the design of flood-control and water-usage management policies. The chapters discuss climatic variability that depends on several factors, i.e., its erratic distribution, topography, seasonal variation, land-use change, anthropogenic activities, etc., demonstrating the overall interconnection between different parameters of hydrological cycles to design modeling approaches that include using soft-computing applications, remote sensing and GIS-based techniques, artificial neural networks, and more. This book will be a standard reference work for disciplines in water resources, soil and water engineering, engineering hydrology, groundwater hydrology, climate change, agrometeorology, agriculture, ecology and environmental science, leading to a way forward for strategy formulation for combating hydrology and climate change.
This book covers a variety of topics regarding environmental practices in our day-to-day lives, as well as topics concerning sustainable development as a broader concept embracing ecological, social, and economic aspects to improve the quality of life for people around the world. Starting with the traditional controversy between the neoclassical economy and sustainable economy, which may be overcome by scientific progress due to more intensive scientific studies of the sustainability paradigm, the book proceeds to discuss various problems and challenges regarding environmental protection and sustainable development in different countries and on different continents. This includes analyses of recent, sometimes fatal mining disasters in South and North America, challenges and opportunities for rural development in Africa and Australia, an exploration of the role of women for sustainable development in Palestine, water safety and water security issues in Asia and Australia, the environmental exploitation of popular tourism destinations like Acapulco, and deforestation in Malaysia, suggesting innovative approaches to turn challenges into opportunities to effectively tackle these problems. Other topics addressed involve sustainable energy creation for future generations, a research survey among Romanian students on sustainable consumption behavior, validity testing for a heat transfer model in a greenhouse, and a case study on sustainability risk management practices at Malaysia's environmentally sensitive companies. The book closes with an examination of highly digitalized Smart Cities as a potentially valuable complement to conventional urban and rural lifestyles in connection with achieving the UN Sustainable Development Goals (SDGs).
This book introduces readers to environmental background investigation, pollution source intensity evaluation and risk assessment approaches used at three main types of groundwater-contaminated sites: municipal domestic waste landfills, hazardous waste landfills and oil-contaminated sites. In addition, typical contaminated sites throughout China are examined to demonstrate how these approaches can be applied for their investigation, assessment and restoration. By reading this book, readers will gain a deeper understanding of the restoration and management of typical groundwater-contaminated sites.
Pulp and Paper Industry: Emerging Waste Water Treatment Technologies is the first book which comprehensively reviews this topic. Over the past decade, pulp and paper companies have continued to focus on minimizing fresh water use and effluent discharges as part of their move towards sustainable operating practices. Three stages-basic conservation, water reuse and water recycling-provide a systematic approach to water resource management. Implementing these stages requires increased financial investment and better utilization of water resources. The ultimate goal for pulp and paper companies is to have effluent-free factories with no negative environmental impact. The traditional water treatment technologies that are used in paper mills are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. This book discusses various measures being adopted by the pulp and paper industry to reduce water consumption and treatment techniques to treat wastewater to recover it for reuse. The book also examines the emerging technologies for treatment of effluents and presents examples of full-scale installations.
This volume provides essential information on the origin and evolution of Greek rivers, as well as their ecological and anthropogenic characteristics. The topics covered include geomythology, biogeography, hydrology, hydrobiology, hydrogeochemistry, geological and biogeochemical processes, anthropogenic pressures and ecological impacts, water management - both in the antiquity and today - and river restoration. The book is divided into four parts, the first of which explores the importance of rivers for ancient Greek civilization and the natural processes affecting their evolution during the Holocene. In the second part, the hydrological, hydrochemical and biological features of Greek rivers and the unique biogeographical characteristics that form the basis for their high biodiversity and endemism are highlighted, while the third part comprehensively discusses the impacts of environmental pollution on the structure and function of Greek river ecosystems. In turn, the final part describes the current socio-economic factors in Greece that are affecting established water management practices, the application of ecohydrological approaches in restoring fragmented rivers, and the lessons learned from restoring aquatic ecosystems in general as a paradigm for understanding and minimizing anthropogenic impacts on water resources, at the Mediterranean scale. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.
This book provides an overview of the current development status of remediation technologies involving electrochemical processes, which are used to clean up soils that are contaminated with different types of contaminants (organics, inorganics, metalloids and radioactive). Written by internationally recognized experts, it comprises 21 chapters describing the characteristics and theoretical foundations of various electrochemical applications of soil remediation. The book's opening section discusses the fundamental properties and characteristics of the soil, which are essential to understand the processes that can most effectively remove organic and inorganic compounds. This part also focuses on the primary processes that contribute to the application of electrochemically assisted remediation, hydrodynamic aspects and kinetics of contaminants in the soil. It also reviews the techniques that have been developed for the treatment of contaminated soils using electrochemistry, and discusses different strategies used to enhance performance, the type of electrode and electrolyte, and the most important operating conditions. In turn, the book's second part deals with practical applications of technologies related to the separation of pollutants from soil. Special emphasis is given to the characteristics of these technologies regarding transport of the contaminants and soil toxicity after treatment. The third part is dedicated to new technologies, including electrokinetic remediation and hybrid approaches, for the treatment of emerging contaminants by ex-situ and in-situ production of strong oxidant species used for soil remediation. It also discusses pre-pilot scale for soil treatment and the use of solar photovoltaic panels as an energy source for powering electrochemical systems, which can reduce both the investment and maintenance costs of electrochemically assisted processes.
In recent years, the adequacy of collected water quality data and the performance of existing monitoring networks have been seriously evaluated for two basic reasons. First, an efficient information system is required to satisfy the needs of water quality management plans and to aid in the decision-making process. Second, this system has to be realized under the constraints of limited financial resources, sampling and analysis facilities, and manpower. Problems observed in available data and shortcomings of current networks have led researchers to focus more critically on the design procedures used. The book is intended to present an up-to-date overview of the current network design procedures and develop basic guidelines to be followed in both the design and the redesign of water quality monitoring networks. The book treats the network design problem in a comprehensive and systematic framework, starting with objectives of monitoring and elaborating on various technical design features, e.g. selection of sampling sites, sampling frequencies, variables to be monitored, and sampling duration. The design procedures presented are those that the authors have recently applied in a number of national and international projects on the design and redesign of water quality monitoring networks. Thus, the book covers real case studies where not only the methods described in the earlier titles are used but also new techniques are introduced. Where earlier methods are used, they are assessed with respect to their efficiency and applicability to real case problems. Audience: Essentially, the framework adopted in the book applies as well to other hydrometric data collection networks besides those of water quality. In this respect, it is expected that planners, designers, scientists, and engineers who are involved in hydrometric network design will benefit from the in-depth approach assumed in this book. It will also be of interest to research and data centers, international programs and organizations related to environmental monitoring. The book may also be used as a reference text in graduate courses of water resources and environmental engineering programs.

This book uses resource economics costing approaches incorporating externalities to estimate the returns for the country's irrigation and demonstrates how underestimating the cost of water leads farmers to overestimate profits. The importance of the subject can be judged in light of the fact that India is the largest user of groundwater both for irrigation and for drinking purposes, pumping twice as much as the United States and six times as much as Europe. Despite water's vital role in ensuring economic security for the nation and farmers alike by supporting more than 70% of food production, water resource economists are yet to impress upon farmers and policymakers the true value of water and the urgent need for its sustainable extraction, recharge and use. In an endeavor to promote more awareness, the book further delineates the roles of the demand side and supply side in the economics of irrigation, and explains how the cost of water varies with the efforts to recharge it, crop patterns, degrees of initial and premature well failure and degrees of externalities. It also discusses the importance of micro-irrigation in the economics of saving water for irrigation, estimating the marginal productivity of water and how it improves with drip irrigation, the economics of water sharing and water markets, optimal control theory in sustainable extraction of water, payment of ecosystem services for water and how India can effectively recover. In closing, the book highlights the role of socioeconomic and hydrogeological factors in the economics of irrigation, which vary considerably across hard rock areas and the resulting limitations on generalizing.

CONTENTS - Part 1 - Introduction - Part 2 - Impurities present in water and their effects on industrial uses - Part 3 - Industrial waters and their quality requirements - Part 4 - Drinking and irrigation water - Part 5 - Impurities present in water and their effects on water treatment systems - PREFACE - It is well known that without water no life can exist on earth. Similarly without water, many of the industries cannot exist, as water is used in multifarious ways in industries. Water is the raw material, water is the ingredient, water is the medium of reaction and water is the conveying medium. Besides, water is used to generate steam and it is the major cooling agent. Without water, washing operations cannot be carried out. Needless to say that each process requires a specific water quality. While every industry is keen on the availability and abundance of water, it is a sad fact that not much importance is bestowed upon the quality of water. Adherence to the quality requirements of water would result in a better product, protection of equipment, increased efficiency and avoidance of losses. Even though the industry in general is very interested to know the quality requirements, there is a dearth of literature and even the available literature is scattered. The intention in writing this book is to provide comprehensive information on the quality requirements of water for each industrial use in a single volume. Almost all the major wet processing industries and quality requirements of water for such industrial processes are described in this book in detail. For easy understanding this book is divided into five parts, namely, 1) Introduction, 2) Impurities present in Water and their Effects on Industrial Uses, 3) Industrial Waters and their Quality Requirements, 4) Drinking and Irrigation water and 5) Impurities present in Water and their Effects on Water Treatment Systems. Every effort is made to provide all the possible information through these sections. Chapters are arranged in alphabetical order for easy access to the required chapter. My hope is that this book will fill that long felt need for the availability of a one volume scientific discussion, hoped to be a boon to all the industries, work managers, plant managers, water treatment personnel, chemists, and water treatment consultants, firms engaged in water treatment programs etc. This book will also serve as a ready reference to students of Industrial Engineering, Chemical Engineering, Industrial Chemistry, Applied chemistry, and to various other faculties of Colleges and Universities.

This book evaluates the history, the present and the future of water markets on 5 continents, beginning with the institutional underpinnings of water markets and factors influencing transaction costs. The book examines markets in seven countries and three different U.S. states, ranging from village-level water markets in Oman to basin wide formal water markets in Australia's Murray-Darling River basin. Introductory chapters on the background of water markets and on transaction costs and policy design are followed by chapter length discussion of water markets as an adaptive response to climate change and of supply reliability in a changing climate. Case studies describe a variety of facets of the design and function of markets around the world: California, Chile, Spain, Oman, Australia, Canada, India and China. In analyzing these real-world examples of markets, the contributors explore water rights and trading of rights between agricultural and urban sectors and the principles and function of option markets. They discuss different sized approaches, from large scale, ministry-level administration of markets to informal arrangements among farmers in the same village, or groups of villages which allocate water without large investment in management and infrastructure. Discussion includes questions of why water market practices have not expanded more rapidly in arid places. The book discusses mechanisms for resolving conflicts between water rights holders as well as between water right holders and third parties impacted by water trades and whether or not public ownership of water rights or use rights should trump private ownership and under what condition. Also covered are new and expanding categories of water use, beyond human consumption, agriculture and industry to new technologies ranging from extracting natural gas from shale to producing biofuels. The book concludes with suggestions for future water markets and offers a realistic picture of how they might change water use and distribution practices going forward.
Groundwater contributes to the sustainable development of many Asian cities by providing water for domestic, industrial and agricultural uses and regulating ecosystem flows. However, groundwater has not always been properly managed, which often has resulted in depletion and degradation of the resource. Groundwater Environment in Asian Cities presents the up-to-date scientific knowledge on groundwater environment in fourteen Asian cities using Driver-Pressure-State-Impact-Response (DPSIR) framework. In detail the book presents the facts and figures of groundwater dependency, problems related to groundwater over exploitation, implementation of various policy instruments and management practices and their results in selected fourteen Asian cities, namely; Bandung (Indonesia), Bangkok (Thailand), Beijing (China), Bishkek (Kyrgyzstan), Chitwan (Nepal), Delhi (India), Dili (East Timor), Ho Chi Minh (Vietnam), Hyderabad (India), Khulna (Bangladesh), Lahore (Pakistan), Seoul (South Korea), Tokyo (Japan), and Yangon (Myanmar). The book provides the one-step platform to get sufficient details about groundwater aquifers, hydrogeology, groundwater status, impacts on groundwater environment and responses (technology, policy, institutional, etc.) deployed in the case studies cities, and therefore, provides a snap-shot of Asian groundwater environments. The theoretical background of the topics discussed along with the case studies help the readers understand the similarities and differences about the status of groundwater development and use in each city. In addition, the information in the book will serve as a baseline for other research such as mitigation of groundwater related problems (e.g., land subsidence), impact of climate change on groundwater, and importance of groundwater for implementing sustainable development goals in future. |
