Generally, conventional water treatment approaches are effective at removing contaminants of emerging concern (CEC) satisfactorily; however, these can sometimes be chemically, energetically, and operationally intensive. In this context, advanced oxidation processes (AOPs) have emerged as sustainable technologies for stopping pollutants from reaching the environment, offering different solutions to many environmental problems. In this book, we present recent developments in AOP technology for treating CECs, including the use of AOPs for the treatment of antibiotics, pharmaceuticals and personal care products, and other organic pollutants. The chapters cover a range of AOP technologies, including photocatalysis, electrochemical oxidation, catalyst, persulfate oxidation, and air plasma. This book highlights the potential of AOPs for treating CECs as well as the importance of considering real water matrices, including palm oil mill effluent waste activated sludge, wastewater treatment plants, and pharmaceutical wastewater, in developing and optimizing AOPs for the treatment of CECs.

The COVID-19 pandemic demonstrated the necessity for highly interdisciplinary, multi-stakeholder collaboration to enable effective public health practice and response. The application of wastewater monitoring to support the pandemic response was demonstrated quickly, leveraging existing scientific and engineering capability to develop rapidly methods that enabled scaling of monitoring programmes across the globe. The science and practice of wastewater monitoring, or wastewater-based epidemiology (WBE) as it is often termed in the context of surveillance, for public health threats is well-documented. As a highly socialised tool, national, regional and international communities of interest have joined efforts to provide evidence of the value of the data derived and its application in practice. While the use of wastewater monitoring to detect and characterise targets of public health concern is not new, COVID-19 and the (re)emergence of rare, novel or unexpected pathogens stresses the importance of continued research and development into the utility of wastewater monitoring and utility of the data it generates. As wastewater monitoring continues to move from the research community into applied public health agencies, there is a need to develop standard methods and data analytics for specific applications. Establishing WBE at the frontier of global public health requires a clearer understanding and acknowledgment of its value by public health policy makers, regulators and government. This book presents a broad view of WBE thinking and practice, delineating the current understanding and future potential of the field. The topics covered range from geographically distinct reports on the use of WBE to inform on pathogen circulation in a population, through technical developments and data utility, to commentaries on future challenges and opportunities including for WBE 'beyond the pandemic'.

This is the Spanish translation of Anaerobic Reactors for Sewage Treatment: Design, Construction and Operation. Anaerobic sewage treatment using UASB reactors has significantly expanded in the last few decades and is now a consolidated technology in some warm climate regions. Several advantages of the anaerobic process make it a more sustainable option for sewage treatment. However, there are still important constraints related to design, construction, and operation of UASB reactors. Conversely, there is enough knowledge, experience, and proven technology that can be used to effectively tackle all the related drawbacks. This book delivers the most relevant techno-scientific developments from academia and water authorities, comprehensively addressing the main aspects of interest in design, construction, and operation of UASB reactors for sewage treatment. Special attention is given to the proper and integrated management of sludge, scum, gaseous emissions, energy recovery, and effluent quality. The main purpose is to provide information and share experiences not yet compiled in the specialized literature on anaerobic sewage treatment. Therefore, a sequence of 12 well-interconnected chapters consolidates the practical knowledge and experiences that important research groups and recognized professionals worldwide have acquired over the past 20 years in demo- and full-scale anaerobic-based sewage treatment plants. Anaerobic Reactors for Sewage Treatment: Design, Construction and Operation can significantly contribute towards a responsible expansion of the anaerobic technology in the world. The book is a valuable tool for engineers, constructors, operators, wastewater utility managers, as well as for students interested in anaerobic processes for sewage treatment. A simple and ready-to-use spreadsheet for the design of UASB reactors for sewage treatment is available for download here.
The first edition of this book was published in 2008 and it went on to become IWA Publishing's bestseller. Clearly there was a need for it because over the twenty years prior to 2008, the knowledge and understanding of wastewater treatment had advanced extensively and moved away from empirically-based approaches to a fundamental first-principles approach based on chemistry, microbiology, physical and bioprocess engineering, mathematics and modelling. However the quantity, complexity and diversity of these new developments was overwhelming for young water professionals, particularly in developing countries without readily available access to advanced-level tertiary education courses in wastewater treatment. For a whole new generation of young scientists and engineers entering the wastewater treatment profession, this book assembled and integrated the postgraduate course material of a dozen or so professors from research groups around the world who have made significant contributions to the advances in wastewater treatment. This material had matured to the degree that it had been codified into mathematical models for simulation with computers. The first edition of the book offered, that upon completion of an in-depth study of its contents, the modern approach of modelling and simulation in wastewater treatment plant design and operation could be embraced with deeper insight, advanced knowledge and greater confidence, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks, or biofilm systems. However, the advances and developments in wastewater treatment have accelerated over the past 12 years since publication of the first edition. While all the chapters of the first edition have been updated to accommodate these advances and developments, some, such as granular sludge, membrane bioreactors, sulphur conversion-based bioprocesses and biofilm reactors which were new in 2008, have matured into new industry approaches and are also now included in this second edition. The target readership of this second edition remains the young water professionals, who will still be active in the field of protecting our precious water resources long after the aging professors who are leading some of these advances have retired. The authors, all still active in the field, are aware that cleaning dirty water has become more complex but that it is even more urgent now than 12 years ago, and offer this second edition to help the young water professionals engage with the scientific and bioprocess engineering principles of wastewater treatment science and technology with deeper insight, advanced knowledge and greater confidence built on stronger competence.
Intermittent Water Supply is common in the majority of countries in South Asia, Latin America, Africa and the Middle East. There are different factors that cause intermittency in water systems such as natural, technical and financial scarcity as well as user behaviour and institutional aspects. Intermittent access to water can have consequences on public health and social equity. Intermittent Water Supply systems are considered as failing systems that are not sustainable in the long-term. A lot of work has been done by researchers and practitioners to better understand these systems, to improve their operation and management, and eventually their conversion to continuous water supply systems. This book addresses the challenges, opportunities and solutions of IWS systems. Authors highlight the importance of these topics and provide innovative solutions to the challenges facing IWS systems. The book is an important contribution to the ongoing efforts to address the challenges of IWS systems and the chapters within it provide valuable insights for researchers and practitioners. In Focus - a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field.

The contribution of this book lies in the historical comparison of infrastructural systems that normally are dealt with separately. The synthesis has been achieved mainly by an extensive literature review of research from a wide range of various fields and by using prime sources to some extent. The comparative and long-term perspective allows similarities and differences to be discovered in the development of arrangements around streets, water, and sanitation. By using the analytical lens of publicness, the author challenges the common belief that these three areas have always been public concerns or obligations. An assumption that relies on the fact that presently they indeed are public infrastructural systems. Furthermore, it is shown that the evolution of municipal streets, water, and sanitation has left a historical legacy which is still affecting the way these infrastructural systems are managed today.

This Scientific and Technical Report (STR) presents the findings of the IWA Task Group on River Water Quality Modelling (RWQM). The task group was formed to create a scientific and technical base from which to formulate standardized, consistent river water quality models and guidelines for their implementation. This STR presents the first outcome in this effort: River Water Quality Model No. 1 (RWQM1). As background to the development of River Water Quality Model No.1, the Task Group completed a critical evaluation of the current state of the practice in water quality modelling. A major limitation in model formulation is the continued reliance on BOD as the primary state variable, despite the fact BOD does not include all biodegradable matter. A related difficulty is the poor representation of benthic flux terms. As a result of these limitations, it is impossible to close mass balances completely in most existing models. These various limitations in current river water quality models impair their predictive ability in situations of marked changes in a river's pollutant load, streamflow, morphometry, or other basic characteristics. RWQM 1 is intended to serve as a framework for river water quality models that overcome these deficiencies in traditional water quality models and most particularly the failure to close mass balances between the water column and sediment. To these ends, the model incorporates fundamental water quality components and processes to characterise carbon, oxygen, nitrogen, and phosphorus (C, O, N, and P) cycling instead of biochemical oxygen demand as used in traditional models. The model is presented in terms of process and components represented via a 'Petersen stoichiometry matrix', the same approach used for the IWA Activated Sludge Models. The full RWQM1 includes 24 components and 30 processes. The report provides detailed examples on reducing the numbers of components and processes to fit specific water quality problems. Thus, the model provides a framework for both complicated and simplified models. Detailed explanations of the model components, process equations, stoichiometric parameters, and kinetic parameters are provided, as are example parameter values and two case studies. The STR is intended to launch a participatory process of model development, application, and refinement. RWQM1 provides a framework for this process, but the goal of the Task Group is to involve water quality professionals worldwide in the continued work developing a new water quality modelling approach. This text will be an invaluable reference for researchers and graduate students specializing in water resources, hydrology, water quality, or environmental modelling in departments of environmental engineering, natural resources, civil engineering, chemical engineering, environmental sciences, and ecology. Water resources engineers, water quality engineers and technical specialists in environmental consultancy, government agencies or regulated industries will also value this critical assessment of the state of practice in water quality modelling. Key Features presents a unique new technical approach to river water quality modelling provides a detailed technical presentation of the RWQM1 water quality process model gives an informative critical evaluation of the state of the practice in water quality modelling, and problems with those practices provides a step by step procedure to develop a water quality model Scientific & Technical Report No. 12

Taking over 10 years to develop, the new EU Water Framework Directive is the most significant legal instrument in the water field to emerge from Brussels for some time and will have a profound effect on how water is managed in Europe over the next 25 years. The book outlines its basic features. It explains how the current approach to water management will have to change in order that European Member states and those countries currently in accession negotiations can meet the requirements of the directive, describing a number of examples of current practices as possible systems which could be used in the new approach. The concept of river basin management is outlined, and the potential institutional problems associated with implementing such a system are discussed including the problems associated with cross-border river basins, a common situation in Europe. Examples of existing river basin authorities and international collaboration are given as possible models. The directive requires the establishment of programmes of measures to improve water status. Some countries already use such a concept, and examples are quoted. As a result of its implementation, the directive aims to achieve good water status in all natural surface waters and groundwater in 15 years. For surface waters, the definition of 'good' is based on a new concept of 'ecological quality' taking into account biology, chemistry and their physical features. For groundwater, it includes quantitative status. The approach taken is an integrated one which has to consider all the naturally occurring and human factors which affect the waters. The difficulties of interpretation of the new concept of 'ecological water status' are discussed and some of the examples of current biological and chemical classification schemes that are used in Europe are examined. The directive also alters the way in which pollution is to be controlled - the 'combined' approach. This concept is explained. The EU Water Framework Directive: An Introduction is an invaluable source of guidance on the implementation of the Water Framework Directive for all those concerned with water management including water quality planners and scientists, pollution control and environmental staff in the water and wastewater industries and environmental regulators who all have to adapt to the new approach to their work.

The study of membrane biofouling has increased strongly in the past four years, compared to the previous twenty two years, indicated by the more than doubling of the number of scientific papers. However, no single source gives an updated overview of biofouling. Biofouling of Spiral Wound Membrane Systems gives a complete and comprehensive overview of all aspects of biofouling, bridging the gap between microbiology, hydraulics and membrane technology. High quality drinking water can be produced with membrane filtration processes like reverse osmosis (RO) and nanofiltration (NF). As the global demand for fresh clean water is increasing, these membrane technologies are increasingly important. One of the most serious problems in RO/NF applications is biofouling - excessive growth of biomass - affecting the performance of the RO/NF systems. This can be due to the increase in pressure drop across membrane elements (feed-concentrate channel), the decrease in membrane permeability or the increase in salt passage. These phenomena result in the need to increase the feed pressure to maintain constant production and to clean the membrane elements chemically. Biofouling of Spiral Wound Membrane Systems relates biomass accumulation in spiral wound RO and NF membrane elements with membrane performance and hydrodynamics and determines parameters influencing biofouling. It focuses on the development of biomass in the feed-concentrate (feed-spacer) channel and its effect on pressure drop and flow distribution. It can be used to develop an integral strategy to control biofouling in spiral wound membrane systems. Most past and present methods to control biofouling have not been very successful. An overview of several potential complementary approaches to solve biofouling is given and an integrated approach for biofouling control is proposed.
The goal of this project was to develop design protocols that integrate uncertainty and water quality considerations into the design process of activated sludge treatment plants in a explicit and quantitative manner. The protocols are based on Monte Carlo simulation using distributions that represent the uncertainty and variability inherent to wastewater loads and model parameters. In the course of the research, outlier identification tools and statistical distributions for activated sludge model parameters were developed. The protocols were applied to an existing activated sludge treatment system to evaluate the effect of solids retention time on effluent ammonia in the context of a uncertain design environment and variable operating conditions. The protocols were also applied to ammonia toxicity in the receiving stream from the plant. The results of these statistical design procedures are an estimate of the probability of design failure as a function design decisions. ** Please note ** VAT is chargeable on this product at a rate of 17.5%, where applicable.

Spanish translation of Nature Based Solutions for Wastewater Treatment. There are 2.4 billion people without improved sanitation and another 2.1 billion with inadequate sanitation (i.e. wastewater drains directly into surface waters), and despite improvements over the past decades, the unsafe management of fecal waste and wastewater continues to present a major risk to public health and the environment (UN, 2016). There is growing interest in low cost sanitation solutions which harness natural systems. However, it can be difficult for wastewater utility managers to understand under what conditions such nature-based solutions (NBS) might be applicable and how best to combine traditional infrastructure, for example an activated sludge treatment plant, with an NBS such as treatment wetlands. There is increasing scientific evidence that treatment systems with designs inspired by nature are highly efficient treatment technologies. The cost-effective design and implementation of ecosystems in wastewater treatment is something that exists and has the potential to be further promoted globally as both a sustainable and practical solution. This book serves as a compilation of technical references, case examples and guidance for applying nature-based solutions for treatment of domestic wastewater, and enables a wide variety of stakeholders to understand the design parameters, removal efficiencies, costs, co-benefits for both people and nature and trade-offs for consideration in their local context. Examples through case studies are from across the globe and provide practical insights into the variety of potentially applicable solutions.
The water sector is in the middle of a paradigm shift from focusing on treatment and meeting discharge permit limits to integrated operation that also enables a circular water economy via water reuse, resource recovery, and system level planning and operation. While the sector has gone through different stages of such revolution, from improving energy efficiency to recovering renewable energy and resources, when it comes to the next step of achieving carbon neutrality or negative emission, it falls behind other infrastructure sectors such as energy and transportation. The water sector carries tremendous potential to decarbonize, from technological advancements, to operational optimization, to policy and behavioural changes. This book aims to fill an important gap for different stakeholders to gain knowledge and skills in this area and equip the water community to further decarbonize the industry and build a carbon-free society and economy. The book goes beyond technology overviews, rather it aims to provide a system level blueprint for decarbonization. It can be a reference book and textbook for graduate students, researchers, practitioners, consultants and policy makers, and it will provide practical guidance for stakeholders to analyse and implement decarbonization measures in their professions.

In the developed world, the connection between water, hygiene and health is taken for granted. However, for the less fortunate majority, access to potable water is non-existent and remains a daily struggle. Bacteria, viruses and parasites in contaminated water cause water borne disease. Of concern are the so-called new emerging pathogens, contributing to water borne disease, one of the biggest human tragedies, killing more than 5 million people each year. About 2.3 billion people suffer from diseases linked to contaminated water and some 6,000 people die daily as a result of this. Some 60% of all infant mortality worldwide is linked to water-related infectious and parasitic diseases. Treating water before use can eliminate most of these waterborne pathogens. The essential starting point is knowledge of the disease-causing organisms, the detection techniques, and the epidemiology, which is the focus of this book. Microbial Waterborne Pathogens provides up-to-date coverage of waterborne microbial pathogens including traditional and emerging pathogens and the latest molecular detection techniques. The link between climate and disease is covered in the book and indicates future approaches to dealing with this important area as we face the effects of global climate change All the existing and emerging pathogens including bacteria, viruses and protozoa are reviewed. The characteristics of each organism are discussed in detail as well as their epidemiology. Methods for the detection of these pathogens, traditional and new are presented. Microbial Waterborne Pathogens provides students, academics and practitioners with a complete reference book on the microbiological quality and safety of potable water.

The book provides an overview of technical sustainable water management in the Global South, mainly in India. The book is structured in five sections: (1) current state and challenges, (2) new age materials in (waste) water treatment, (3) new technologies developed for (waste) water treatment, (4) sensors, (5) urban water infrastructure. Section-1 provides the latest information about the status and challenges for sustainable water management in India, from the perspective of water quality, industrial and domestic wastewater treatment, urban water infrastructure and policy and governance towards water security. Section 2 deals with new age materials for water and wastewater treatment. This part discusses new framework solids for water purification, new materials for arsenic and fluoride removal, nanocomposites for water and wastewater treatment and removal of hazardous materials, and toxicity of these materials. Section 3 of the book presents the new technologies developed for water and wastewater treatment; dealing with pulsed power technology, constructed wetlands, nutrient recovery, low-cost filters and pollution abatement using waste derived materials. Section 4 of the book focuses on sensors, presenting the development of low-cost colorimetric sensors for eutrophying ions, sensors for conductivity and flow parameters, and multi-analyte assessment for water quality. Finally, Section 5 addresses the issues related to urban water infrastructure, sustainable urban drainage and integrated flood and water scarcity management. This section also discusses virtual water. The unique feature of this edited volume is the special perspective on emerging economies in the Global South, such as India. It provides information about adaption of technologies, development of new technologies, and management practices which are context driven and region specific. It also deals with economical and easy to use sensors for large scale monitoring of water quality and water quantity parameters.
