Population growth and industrial development have increased the amount of wastewater generated by urban areas, and one of the major problems facing industrialized nations is the contamination of the environment by hazardous chemicals. Therefore, to meet the standards, suitable treatment alternatives should be established. Advanced Oxidation Processes (AOPs) in Water and Wastewater Treatment is a pivotal reference source that provides vital research on the current, green, and advanced technologies for wastewater treatment. While highlighting topics such as groundwater treatment, environmental legislation, and oxidation processes, this publication explores the contamination of environments by hazardous chemicals as well as the methods of decontamination and the reduction of negative effects on the environment. This book is a vital reference source for environmental engineers, waste authorities, solid waste management companies, landfill operators, legislators, environmentalists, and academicians seeking current research on achieving sustainable management for wastewater treatment.

This book asks under which conditions cooperation is in the interest of the riparian countries sharing international waters, and how institutions must be designed to realize potential gains of cooperation. The author, Ines Dombrowsky, develops a conceptual framework that draws upon different economic theories, including the theory of external effects, non-cooperative game theory and transaction costs economics. She distinguishes the different types of externality problems inherent in international water management and specifies the institutional prerequisites for cooperation. She argues that the respective problems differ with respect to the need to define property rights and to establish enforcement mechanisms. The book also explores the role of issue linkage and of international organizations to foster cooperation. The theoretic considerations are compared and contrasted with the findings of a global review of international water treaties and organizations. By taking hydrological and legal aspects into account, this book provides an interdisciplinary contribution at the interface of hydrology, law and economics. As such, it is addressed to scholars, practitioners and policy-makers, including economists, political scientists, international lawyers, natural scientists, and water resource managers.

When it comes to water, we are fed a daily diet of doom and gloom, of a looming crisis: wars of the future will be over water; nearly one-billion people lack access to clean water; river basins are closed so there is no more water to be allocated despite ever-growing demand; aquifers are overdrawn to such an extent that a global food crisis is just around the corner and major cities, such as Bangkok and Mexico, are sinking. And let us not forget about pollution or vector-borne diseases.

The challenges for sustainable water management are massive. Yet, as shown in this book, there are many positives to be drawn from the southern African experience. Despite abiding conditions of economic underdevelopment and social inequality, people rise to the challenge, oftentimes out of necessity and through self-help, but sometimes through creative coalitions operating at different scales - from the local to the global - and across issue areas - from transboundary governance to urban water supply.

This first volume in the Off-Centre series argues that we must learn to see water and the region differently if we are to meet present challenges and better prepare for an uncertain, climate-changing future.

Encompassing papers form the 2019 Water and Society Conference, this book is a collection of latest trans-disciplinary research on issues related to the nature of water, and its use and exploitation by society. This book demonstrates the need to bridge the gap between specialists in physical sciences, biology, environmental sciences and health. Over the centuries, civilisations have relied on the availability of clean and inexpensive water. This can no longer be taken for granted as the need for water continues to increase due to the pressure from growing global population demanding higher living standards. Agriculture and industry, major users of water, are at the same time those that contribute to its contamination. Water distribution networks in urban areas, as well as soiled water collection systems, present serious problems in response to a growing population as well as the need to maintain ageing infrastructures. Many technologically feasible solutions, such as desalination or pumping systems are energy demanding but, as costs rise, the techniques currently developed may need to be re-assessed. The research contained in this book addresses the interaction between water and energy systems. The socio-political implications of a world short of clean, easily available water are enormous. It will lead to realignments in international politics and the emergence of new centres of power in the world. The following list covers some of the subjects included in this book: Water resources management; Agribusiness; Water as a human right; Water quality; Water resources contamination; Sanitation and health; Water and disaster management; Policy and legislation; Future water demands; Irrigation and water management; Management of catchments; Groundwater management and conservation.

This book highlights novel materials for dye-containing wastewater treatment and presents an up-to-date information on dye degradation/adsorption using new promising materials such as nanocomposites.

This book offers essential information on geospatial technologies for water resource management and highlights the latest GIS and geostatistics techniques as they relate to groundwater. Groundwater is inarguably India's single most important natural resource. It is the foundation of millions of Indian farmers' livelihood security and the primary source of drinking water for a vast majority of Indians in rural and urban areas. The prospects of continued high rates of growth in the Indian economy will, to a great extent, depend on how judiciously we can manage groundwater in the years to come. Over the past three decades, India has emerged as by far the single largest consumer of groundwater in the world. Though groundwater has made the country self-sufficient in terms of food, we face a crisis of dwindling water tables and declining water quality. Deep drilling by tube wells, which was once part of the solution to water shortages, is now in danger of becoming part of the problem. Consequently, we urgently need to focus our efforts on the sustainable and equitable management of groundwater. Addressing that need, this book presents novel advances in and applications of RS–GIS and geostatistical techniques to the research community in a precise and straightforward manner.

Due to an ever-decreasing supply in raw materials and stringent constraints on conventional energy sources, demand for lightweight, efficient and low cost structures has become crucially important in modern engineering design. This requires engineers to search for optimal and robust design options to address design problems that are often large in scale and highly nonlinear, making finding solutions challenging. In the past two decades, metaheuristic algorithms have shown promising power, efficiency and versatility in solving these difficult optimization problems. This book examines the latest developments of metaheuristics and their applications in water, geotechnical and transport engineering offering practical case studies as examples to demonstrate real world applications. Topics cover a range of areas within engineering, including reviews of optimization algorithms, artificial intelligence, cuckoo search, genetic programming, neural networks, multivariate adaptive regression, swarm intelligence, genetic algorithms, ant colony optimization, evolutionary multiobjective optimization with diverse applications in engineering such as behavior of materials, geotechnical design, flood control, water distribution and signal networks. This book can serve as a supplementary text for design courses and computation in engineering as well as a reference for researchers and engineers in metaheursitics, optimization in civil engineering and computational intelligence.

Low-pressure (MF and UF) membranes can remove nearly all microbial pathogens as long as the integrity of the membranes remains intact. Membrane integrity testing identifies tiny defects in MF and UF membranes. The book describes various methods for membrane integrity testing. You will learn the types and causes of integrity breaches, tests to discover them, and how to establish a membrane integrity testing program.To comply with disinfection regulations, utilities using low-pressure membranes for drinking water treatment must validate and verify the removal efficiency of the targeted contaminant through integrity testing. Owners and operators of water treatment systems that use MF or UF membranes should use the testing methods described in this book to protect public health.

This book provides a systematic exposition of the design features of constructed wetlands, and their management (in terms of siting, physical maintenance, and operation). Only very few books (or chapters) have been published on constructed wetlands in tropical conditions and none are current. The selection of plant species, managing their growth and harvesting cycles, and the impact these have on the attenuation of organic and inorganic pollutants, nutrients, and pathogens would be of interest to students and practitioners of the art working under tropical conditions. The potential of constructed wetlands as a low-cost intervention for developing countries in tropical regions that faced water pollution problems, in particular, deserves to be explored systematically.

This book presents the phylogeny, taxonomy and biogeography of freshwater red algae. Its content is divided into five chapters. The first chapter provides a brief history of freshwater red algal research, habits and collecting methods, general biogeographic trends and an overview of the taxonomic/phylogenetic placement of freshwater taxa. The other four chapters are taxonomic treatments of non-marine red algae based on taxonomic levels, i.e. classes within the phylum Rhodophyta, orders within each class, families within each order, and genera within each family. Descriptions, phylogenetic data (including numerous trees), geographic range (maps for most species) and dichotomous keys for identification are presented. Comprehensive data are provided for more than 220 species.

This book provides a comprehensive overview of the current knowledge on the fate and interaction of pharmaceuticals in soil-crop systems. It addresses the principles of their transport, uptake and metabolism and reviews methodologies for their analytical determination. It also discusses ecotoxicological effects arising from their presence and highlights bioremediation approaches for their removal. The use of treated wastewater to irrigate crops is becoming more widespread in regions where freshwater is limited. This practice conserves freshwater resources and contributes to nutrient recycling. However, concerns remain regarding the safety of irrigation with treated wastewater since it contains residues of pharmaceuticals that have survived treatment, which means that soil and fauna are potentially exposed to these xenobiotics. Various pathways govern the fate of pharmaceuticals in crop-soil systems, including soil degradation; formation of non-extractable residues; uptake by soil-dwelling organisms (e.g. earthworms); and uptake, transport, and metabolism in agricultural crops. Investigations into these aspects have only recently been initiated, and there is still a long way to go before a meaningful assessment of the impact of wastewater has been completed.
