Download or read book Estimating VOC Emissions from Waste Water Treatment Units Using a Flow Through Flux Chamber and Chemdat7 written by KR. Comey and published by . This book was released on 1996 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is increasing concern in the petroleum industry for a practical method of accurately quantifying refinery volatile organic compound (VOC) emissions. The U.S. Environmental Protection Agency (EPA) developed the Chemdat7 emission rate model to predict VOC emissions from surface impoundments, waste-water treatment plants, and land farms for regulatory purposes. Previous studies have indicated that Chemdat7 significantly overpredicted VOC emissions. Much of the model evaluation of Chemdat7 used the EPA isolation environmental flux chamber. There are some concerns in using the EPA isolation flux chamber for measurement of fugitive emissions from surface impoundments due to its effect on ambient wind velocity, temperature, and solar radiation. This paper discusses an alternative method for quantifying VOC emissions from waste-water treatment units using a flow-through environmental flux chamber, and includes a comparison of the results from the flow-through chamber with that of the Chemdat7 model.

This book was released on 1994 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: In accordance with the 1990 Clean Air Act Amendments (CAAA), this research conducts an evaluation of the potential emission of volatile organic compounds (VOCs) from selected Air Force wastewater treatment plants. Using a conservative mass balance analysis and process specific simulation models, volatile organic emission estimates are calculated for four individual facilities--Edwards AFB, Luke AFB, McGuire AFB, and McClellan AFB--which represent a cross section of the current inventory of USAF wastewater plants in ozone nonattainment areas. From these calculations, maximum facility emissions are determined which represent the upper limit for the potential VOC emissions from these wastewater plants. Based on the calculated emission estimates, each selected wastewater facility is evaluated as a potential major stationary source of volatile organic emissions under both Title I of the 1990 CAAA and the plant's governing Clean Air Act state implementation plan. Next, the potential impact of the specific volatile organics being emitted is discussed in terms of their relative reactivity and individual contribution to tropospheric ozone formation. Finally, a relative comparison is made between the estimated VOC emissions for the selected wastewater facilities and the total VOC emissions for their respective host installations.

This book was released on 1993 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assessment and Control of VOC Emissions from Waste Treatment and Disposal Facilities Thomas T. Shen, Ph.D., Charles Schmidt, Ph.D., and Thomas Card The complications surrounding Volatile Organic Compound (VOC) emissions have emerged as a matter of increasing environmental attention and concern, due largely to the huge quantities involved, their known toxicity, and their suspected carcinogenicity. Assessment and Control of VOC Emissions from Waste Treatment and Disposal Facilities is the first book to both thoroughly explore the topic and present the entire range of environmentally and economically viable solutions. The authors address the most recent developments, the newest applications, and the latest methodological advances in the field. The book includes sections on: waste characterizations, such as vapor pressure, solubility, molecular weights, and more emission mechanisms including volatilization, hydrolysis, photodecomposition, biodegradation, and incineration various types of VOC emission sources the latest regulatory information on The Resource Conservation and Recovery Act (RCRA), The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the Clean Air Act (CAA) the entire range of measuring and monitoring approaches for assessing VOC emission rates VOC pathway analyses toxicity, exposure, and basic information about conducting health risk assessments all available control technologies and their costs elaborate, mathematical models and real-life case studies Assessment and Control of VOC Emissions from Waste Treatment and Disposal Facilities is ideal as both a reference and a training text for regulatory engineers, facility environmental managers, and anyone involved in atmospheric sciences. This field-guide and teaching text is invaluable to a wide cross-section of professionals, educators, and students in the chemical, petroleum, and environmental regulatory communities.

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.

This book was released on 2004 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Publicly Owned Treatment Works (POTWs) have come to be examined by the EPA as a major source of Hazardous Air Pollutant (HAP) emission. The 1990 Clean Air Act Amendments as well as state and local regulations, has required POTWs to implement maximum achievable control technologies, MACT, to meet the new regulations. A majority of the HAPs that are emitted are Volatile Organic Compounds (VOCs). Many of these HAPs are considered to be carcinogens or precursors to ozone formation. VOC emission from wastewater treatment plants can occur through a variety of mechanisms including volatilization, evaporation, biodegradation, and photodecomposition; of which, volatilization being the most significant occurring largely in the aeration basins. HAPs are stripped from wastewater in low concentrations over a large surface area. The low concentration and large area make it extremely inefficient and costly to treat polluted air using conventional methods. Recent studies have shown that off gas can be greatly reduced by using a circulating aeration system (CAS). A circulating aeration system requires the capture of off-gas at the aeration basin by an enclosure and the circulation of a percentage back through the system. Fresh air would be mixed; in proportion to the wasted off-gas, with the circulated gas, while only a fraction of the off-gas would be emitted to the atmosphere. Circulating aeration system recycles a percentage of the off-gas back into the system. The use of a CAS lengthens the retention time and increases the possibility for further biodegradation breakdown of compounds. The off gas control also becomes more manageable. With a higher off gas concentration, conventional methods of pollutant control become more economical and efficient. Effects of a CAS are compound specific, however biodegradation rates appear to improve and emissions are reduced drastically. Compounds of high degradability and high volatility, biodegradation are significantly improved. Compounds, such as chloroform, which exhibit high volatility and low degradability air emissions are significantly reduced, but biodegradation is only slightly increased. A large portion of VOCs will remain in the wastewater especially if they have poor degradabilitys.
