Download or read book N2O and CH4 Emission from Wastewater Collection and Treatment Systems written by Jeff Foley and published by IWA Publishing. This book was released on 2015-05-15 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a world where there is a growing awareness of the possible effects of human activities on climate change, there is a need to identify the emission of greenhouse gases (GHG) from wastewater treatment plants (WWTPs). As a result of this growing awareness, governments started to implement regulations that require water authorities to report their GHG emissions. With these developments there exists a strong need for adequate insight into the emissions of N2O and CH4. With this insight water authorities would be able to estimate and finally reduce their emissions. The overall objectives of the different research programs performed by partners of the GWRC members WERF (United States of America), WSAA (Australia), CIRSEE-Suez (France) and STOWA (the Netherlands) were: To define the origin of N2O emission. To understand the formation processes of N2O. To identify the level of CH4 emissions from wastewater collection and treatment systems. To evaluate the use of generic emission factors to estimate the emission of N2O from individual plants

Download or read book Greenhouse Gas Emission and Mitigation in Municipal Wastewater Treatment Plants written by Xinmin Zhan and published by IWA Publishing. This book was released on 2018-01-15 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Greenhouse Gas Emissions from Ecotechnologies for Wastewater Treatment written by Juan Pablo Silva Vinasco and published by CRC Press. This book was released on 2021-02-25 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotechnologies for wastewater treatment (EWWT) have been used as a cost-effective alternative to conventional wastewater treatment methods for improving the removal of organic carbon, nutrients and pathogenic microorganisms from wastewater. However, due to biochemical transformations of organic matter and nutrients EWWT are net sources of CO2, CH4 and N2O greenhouse gases (GHGs), which may be transferred into the atmosphere contributing to global warming. Greenhouse Gas Emissions from Ecotechnologies for Wastewater Treatment provides scientific information about greenhouse gas, such as CO2, CH4 and N2O, generation and emissions from different municipal EWWT. The main EWWT considered in this book are anaerobic ponds, facultative ponds, duckweed-based ponds, and a freshwater natural wetland perturbed by anthropogenic activities such as wastewater discharge and nutrients from agricultural run-off. The book includes a full literature review of recent publications about GHGs emissions from EWWT. It also introduces the calculation of GHGs flux using a static chamber technique. Besides, the book presents information on the influence of environmental factors such as temperature, pH, DO, and nutrients on GHG emissions produced in EWWT under tropical conditions. This book will be a useful reference for researches and students interested in the broader area of water and climate change subjects. The publication may also be of interest to policy makers concerned with climate change, water sector planning, and wastewater treatment.

Download or read book Nitrous Oxide Emissions from Wastewater Treatment Processes and Process Parameters Affecting Emissions written by Shannon Kusaka Cavanaugh and published by . This book was released on 2021 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most wastewater treatment plants in the United States must be upgraded to reduce nutrient discharges. These improvements are needed to meet upcoming permit requirements and to prevent negative environmental impacts like eutrophication of receiving water bodies. However, one of the potential side-effects of increased nitrogen removal in wastewater treatment processes is increased nitrous oxide (N2O) emissions from biological nitrification and denitrification. N2O is a greenhouse gas (GHG) approximately 300 times stronger than an equivalent amount of CO2; thus, it is imperative to (1) establish comprehensive methodologies to accurately quantify N2O emissions from full-scale treatment processes and (2) understand the relevant process parameters and microbiology involved in emissions from wastewater treatment. This serves to ultimately minimize emissions (and therefore the carbon footprint) of wastewater treatment plants (WWTPs). To address this, emissions from two wastewater treatment processes were quantified, and relevant process parameters and microbial emission pathways were investigated. While the two treatment systems differ in terms of scale and processes utilized, both are innovative wastewater treatment technologies designed for efficient use of space and nutrient removal. (1) At Brightwater Treatment Plant (Woodinville, WA), aqueous and gaseous N2O monitoring techniques were employed at a full-scale membrane bioreactor (MBR) for 5.5 months. To the knowledge of the investigators, this campaign was the most comprehensive study of a fully covered MBR to date. Emission estimates from both aqueous and gaseous analyzers were compared to determine their reliability, and the average emission factor (using data from both analyzers) was 0.58% of plant influent total Kjeldahl nitrogen (TKN) emitted as N2O-N. Emissions were positively correlated with influent pH, nitrification efficiency, and aeration basin/effluent NH4+and NO3−. They correlated negatively with primary effluent COD:N ratio and effluent pH, signifying that nitrification was likely the dominant N2O-production pathway. (2) A laboratory-scale, aerobic granular sludge (AGS) sequencing batch reactor (SBR) was operated for 11 months to measure N2O emissions with full phosphate removal and simultaneous nitrification-denitrification (SND). The reactor was operated at varying dissolved oxygen (DO) concentrations and with nitrite (NO2−) spikes to investigate the impact of these process parameters on emissions. Increased DO and NO2- concentrations were associated with increased emissions. N2O was minimized at a dissolved oxygen concentration of 1 mg O2 L−1, with an emission factor of 0.18% of oxidized NH3-N emitted as N2O-N. This emission factor is lower than many previously reported factors from AGS reactors. Molecular analyses revealed a population of microbes capable of shortcut nitrogen removal, which is advantageous for wastewater treatment because of decreased oxygen and carbon requirements.

Download or read book Airborne Occupational Hazards in Sewer Systems written by Amy Forsgren and published by CRC Press. This book was released on 2016-12-01 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sewer systems fall into the category "out of sight, out of mind" – they seldom excite interest. But when things go wrong with the air in the sewer system, they go very wrong. Consequences can be dramatic and devastating: sewer workers killed instantly by poisonous gas when they lift a sewer lid, or entire suburban blocks levelled by explosions. This book describes the atmospheric dangers commonly found in the sewer system. It provides easily-understood explanations of the science behind the hazards, combined with real-life examples of when things went dramatically wrong.

Download or read book Alternative Water Supply Systems written by Fayyaz Ali Memon and published by IWA Publishing. This book was released on 2014-10-15 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to climate change related uncertainties and anticipated population growth, different parts of the developing and the developed world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Alternative Water Supply Systems covers technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining. A number of case studies from the UK, the USA, Australia and the developing world are presented to discuss associated environmental and health implications. The book provides insights into a range of aspects associated with alternative water supply systems and an evidence base (through case studies) on potential water savings and trade-offs. The information organized in the book is aimed at facilitating wider uptake of context specific alternatives at a decentralized scale mainly in urban areas. This book is a key reference for postgraduate level students and researchers interested in environmental engineering, water resources management, urban planning and resource efficiency, water demand management, building service engineering and sustainable architecture. It provides practical insights for water professionals such as systems designers, operators, and decision makers responsible for planning and delivering sustainable water management in urban areas through the implementation of decentralized water recycling.

Available in PDF, EPUB and Kindle. Book excerpt: The ability to accurately monitor, record, report and verify greenhouse gas emissions is the cornerstone of any effective policy to mitigate climate change. Accounting for Carbon provides the first authoritative overview of the monitoring, reporting and verification (MRV) of emissions from the industrial site, project and company level to the regional and national level. It describes the MRV procedures in place in more than fifteen of the most important policy frameworks - such as emissions trading systems in Europe, Australia, California and China, and the United Nations Framework Convention on Climate Change - and compares them along key criteria such as scope, cost, uncertainty and flexibility. This book draws on the work of engineers and economists to provide a practical guide to help government and non-governmental policymakers and key stakeholders in industry to better understand different MRV requirements, the key trade-offs faced by regulators and the choices made by up-and-running carbon pricing initiatives.
