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.

The wide adoption of wastewater treatment processes and use of novel technologies for improvement of nitrogen and phosphorus removals from wastewater have been introduced to meet stringent discharge standards. Municipal wastewater treatment plants (MWWTPs) are one of major contributors to the increase in the global GHG emissions and therefore it is necessary to carry out intensive studies on quantification, assessment and characterization of GHG emissions in wastewater treatment plants, on the life cycle assessment from GHG emission prospective, and on the GHG mitigation strategies. Greenhouse Gas Emission and Mitigation in Municipal Wastewater Treatment Plants summarizes the recent development in studies of greenhouse gas emissions (N2O, CH4 and CO2) in MWWTPs. It also summarizes the development in life cycle assessment on GHG emissions in consideration of the energy usage in MWWTPs. The strategies in mitigating GHG emissions are discussed and the book provides an overview for researchers, students, water professionals and policy makers on GHG emission and mitigation in MWWTPS and industrial wastewater treatment processes. The book is a valuable resource for undergraduate and postgraduate students in the water, climate, and energy areas of research. It is also a useful reference source for water professionals, government policy makers, and research institutes.

Special Offer: Cao Ye Shi Author Set - Buy all three books together and save a total £76! Mass Flow and Energy Efficiency of Municipal Wastewater Treatment Plants presents the results of a series of studies that examined the mass flow and balance, and energy efficiency, of municipal wastewater treatment plants; it offers a vision of the future for municipal wastewater treatment plants. These studies were undertaken as part of the R & D program of the Public Utilities Board (PUB), Singapore. The book covers the latest practical and academic developments and provides: a detailed picture of the mass flow and transfer of Chemical Oxygen Demand (COD), solids, nitrogen and phosphorus and energy efficiency in a large municipal wastewater treatment plants in Singapore. The results are compared with the Strass wastewater treatment plant, Austria, which reaches energy self-sufficiency, and the approaches for improvement are proposed. a description of the biological conversions and mass flow and energy recovery in an up-flow anaerobic sludge blanket reactor - activated sludge process (UASB-ASP) - and compares this to the conventional activated sludge process. a comprehensive and critical review of the current state of the art of energy efficiency of municipal wastewater treatment plants including benchmarks, best available technologies and practices in energy saving and recovery, institution policies, and road maps to high energy recovery and high efficiency plants. a vision of future wastewater treatment plants including the major challenges of the paradigm shift from waste removal to resource recovery, technologies and processes to be studied, integrated sanitation system and management and policies. Mass Flow and Energy Efficiency of Municipal Wastewater Treatment Plants is a valuable reference on energy and sustainable management of municipal wastewater treatment plants, and will be especially useful for process and design researchers in wastewater research institutions, engineers, consultants and managers in water companies and water utilities, as well as students and academic staff in civil/sanitation/environment departments in universities.

MUNICIPAL SOLID WASTE TO ENERGY CONVERSION PROCESSES A TECHNICAL AND ECONOMIC REVIEW OF EMERGING WASTE DISPOSAL TECHNOLOGIES Intended for a wide audience ranging from engineers and academics to decision-makers in both the public and private sectors, Municipal Solid Waste to Energy Conversion Processes: Economic, Technical, and Renewable Comparisons reviews the current state of the solid waste disposal industry. It details how the proven plasma gasification technology can be used to manage Municipal Solid Waste (MSW) and to generate energy and revenues for local communities in an environmentally safe manner with essentially no wastes. Beginning with an introduction to pyrolysis/gasification and combustion technologies, the book provides many case studies on various waste-to-energy (WTE) technologies and creates an economic and technical baseline from which all current and emerging WTE technologies could be compared and evaluated. Topics include: Pyrolysis/gasification technology, the most suitable and economically viable approach for the management of wastes Combustion technology Other renewable energy resources including wind and hydroelectric energy Plasma economics Cash flows as a revenue source for waste solids-to-energy management Plant operations, with an independent case study of Eco-Valley plant in Utashinai, Japan Extensive case studies of garbage to liquid fuels, wastes to electricity, and wastes to power ethanol plants illustrate how currently generated MSW and past wastes in landfills can be processed with proven plasma gasification technology to eliminate air and water pollution from landfills.

In communities all around the world, water supplies are coming under increasing pressure as population growth, climate change, pollution, and changes in land use affect water quantity and quality. To address existing and anticipated water shortages, many communities are working to increase water conservation and are seeking alternative sources of water. Water reuse- the sue of treated wastewater, or "reclaimed" water, for beneficial purposes such as drinking, irrigation, or industrial uses- is one option that has helped some communities significantly expand their water supplies. Understanding Water Reuse summarizes the main findings of the National Research Council report Water Reuse: Expanding the Nation's Water Supply Through Reuse of Municipal Wastewater. The report provides an overview of the options and outlook for water reuse in the United States, discusses water treatment technologies and potential uses of reclaimed water, and presents a new analysis that compares the risks of drinking reclaimed water to those of drinking water from traditional sources.
