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

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.

Book Synopsis Investigation of Nitrous Oxide Flux in Wastewater Treatment Process by : Joseph Park
Download or read book Investigation of Nitrous Oxide Flux in Wastewater Treatment Process written by Joseph Park and published by LAP Lambert Academic Publishing. This book was released on 2011-09 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural nitrogen cycle has been disturbed by the raise of anthropogenic nitrogen fixations. Anthropogenic disturbance on the environment causes eutrophication, decrease in biodiversity, acidification of soil and raise in nitrous oxide emission. To restore the balance, nitrogen is required to be removed via processes such as wastewater treatment. However, it is suggested that nitrous oxide emission occurs during wastewater treatment process. Investigation on the nitrous oxide emission during wastewater treatment process was necessary. Through literature reviews, the nitrous oxide emission factors in cell level have been discussed which identified oxygen, carbon substrate and nitrite as the main emission factors. The correlation analysis on the effect of amount of oxygen on nitrous oxide mission at activated sludge process has been conducted. Moreover, the potential nitrous oxide emission in rivers and estuaries with the remaining nitrogen has been investigated.

Book Synopsis Greenhouse Gas Emission and Mitigation in Municipal Wastewater Treatment Plants by : Xinmin Zhan
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.
