The Bureau of Reclamation and Sandia National Laboratories jointly developed the Roadmap to serve as a strategic research pathway for desalination and water purification technologies to meet future water needs. The book recommends that the Roadmap include a sharper focus on the research and technological advancements needed to reach the long-term objectives. The book also suggests that the environmental, economic, and social costs of energy required by increased dependence on desalination be examined. Strategies for implementing the Roadmap initiative are provided.

The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.
Economic development, population growth, and environmental pollution evolving in many parts of the world are placing great demands on existing resources of fresh water and reflecting a "water crisis". Resource management, efficient utilization of the water resources, and above all water purification are all alternatives to resolve the water crisis. Purification approaches include traditional approaches that have lasted for several centuries without major modifications as well as new innovative approaches. This book covers a number of water quality issues relevant to either improving the existing treatment methods or to new advanced approaches. The book has 15 chapters distributed over four sections titled: [1] Management and Modeling of Treatment Systems, [2] Advanced Treatment Processes, [3] Treatment of Organic-contaminated Water, and [4] Advanced Monitoring Techniques.
Sewage Treatment Plants: Economic Evaluation of Innovative Technologies for Energy Efficiency aims to show how cost saving can be achieved in sewage treatment plants through implementation of novel, energy efficient technologies or modification of the conventional, energy demanding treatment facilities towards the concept of energy streamlining. The book brings together knowledge from Engineering, Economics, Utility Management and Practice and helps to provide a better understanding of the real economic value with methodologies and practices about innovative energy technologies and policies in sewage treatment plants.
Smart Solutions for Wastewater: Road-mapping the Transition to Circular Economy, the latest release in the Current Developments in Biotechnology and Bioengineering presents up-to-date information on research and technological developments of resource recovery in wastewater treatment in terms of carbon, nutrients and energy. The book fulfils the gaps and current challenges that hinder the application of resource recovery facilities in wastewater treatment plants, discusses knowledge gaps, provides future research perspectives, and discusses strategies to solve problems from a circular economy perspective. It is an excellent, interdisciplinary and updated overview of technologies in terms of potential yields, pollutants removal, nutrients recovery and energy production. - Covers different aspects of resource recovery technologies and research gaps in wastewater treatment - Focuses on different MBR configurations and systems/hybrid systems in treating a large variety of wastewaters - Provides state-of-the-art technology developments, including technology, advantages and challenges as well as strategies to overcome limitations - Includes technologies for managing sewage sludge in order to foster solutions for recovering in a circular economy context
This book, edited by members of the Committee of Future Energy and Social Systems, The Society of Chemical Engineers, Japan, describes energy technology roadmaps for Japan post-Fukushima. In this work, energy technology experts show quantitatively the advantages and disadvantages of major energy technologies with which they are involved, in a unified chapter structure with figures illustrating the technology development perspectives. The future energy vision for Japan together with the pathway is quantitatively discussed, explicitly considering the contributions of individual energy technology by referring to the technology roadmaps. The pathways for future energy vision thus derived will be useful not only for all energy researchers but also for graduate students in the field to grasp the potential of the technologies and future energy system of Japan.
• New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.
