This book was released on 2014-12-24 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2012 in the subject Chemistry - Bio-chemistry, , course: Master Degree, language: English, abstract: Modern air pollution control technologies have emerged over the past 40 years to mitigate emission problems in industrial facilities and thereby comply with environmental regulations. A variety of technologies have been developed to meet the needs of both the industries and the regulatory agencies keeping in view the techno economics. Some air pollutants like H2S, NH3 and VOC’s are emitted in the industry causes odour and this not only causes occupational health but also damages public image of the company. Engineered biofiltration is a sustainable technology for VOC and odor control. Bio-filtration is a method of pollution control in which pollutants are biologically degraded using microorganisms. Generally, the energy demands for biofiltration are one-fourth to one-tenth that of physico-chemical destructive technologies. Biofilters are being developed and effectively used for a wide variety of industries, including wood products, paint manufacturing, petroleum remediation etc. Biofilters are cost-effective and straightforward options for pollutants capable of biodegrading reasonably easily. Triethylamine(TEA) is a Volatile organic compound widely used as a catalyst for polymerization reactions and a solvent and corrosion inhibitor in industry and it is also used as an intermediate in the production of various chemicals, including pesticides. It is necessary to remove TEA from water and gas in the environment. TEA gas-phase bio treatment has emerged as an effective and inexpensive alternative to conventional physicochemical treatment systems. The technology is still under development in terms of economics, equipment, process kinetics, and operational skills and different layouts and flow trains are being proposed including biofiltration, biotrickling filter, and bioscrubber. In the present work, studies are being carried out on biofilter contaminated with TEA. The contaminated gas is passed through a packed bed where TEA compound is absorbed into the biofilm in which diffusion and aerobic biodegradation occur simultaneously in a complex set of physical, chemical and biological interactions. Therefore, selection of suitable microbial consortia and biofilter configuration is very important from commercial perspective.

This book was released on 2013-12-11 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph consists of manuscripts submitted by invited speakers who participated in the symposium "Industrial Environmental Chemistry: Waste Minimization in Industrial Processes and Remediation of Hazardous Waste," held March 24-26, 1992, at Texas A&M University. This meeting was the tenth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The program was developed by an academic-industrial steering committee consisting of the co-chairmen, Professors Donald T. Sawyer and Arthur E. Martell of the Texas A&M University Chemistry Department, and members appointed by the sponsoring companies: Bernie A. Allen, Jr., Dow Chemical USA; Kirk W. Brown, Texas A&M University; Abraham Clearfield, Texas A&M University; Greg Leyes, Monsanto Company; Jay Warner, Hoechst-Celanese Corporation; Paul M. Zakriski, BF Goodrich Company; and Emile A. Schweikert, Texas A&M University (IUCCP Coordinator). The subject of this conference reflects the interest that has developed in academic institutions and industry for technological solutions to environmental contamination by industrial wastes. Progress is most likely with strategies that minimize waste production from industrial processes. Clearly the key to the protection and preservation of the environment will be through R&D that optimizes chemical processes to minimize or eliminate waste streams. Eleven of the papers are directed to waste minimization. An additional ten papers discuss chemical and biological remediation strategies for hazardous wastes that contaminate soils, sludges, and water.

Download or read book Bioreactors for Waste Gas Treatment written by C. Kennes and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air pollution, a major concern at the end of the 20th century, still remains a significant problem to be solved today. Traditionally, industrial waste gases have primarily been treated through physical or chemical methods. The search for new, efficient, and cost-effective alternative technologies has led to the development and, more recently, the improvement of gas phase bioreactors. This book is the first single text to provide a complete, comprehensive picture of all major biological reactors suitable for solving air pollution problems. The text describes the main features and covers the major aspects, from microbiological to engineering, as well as economic aspects, of the different types of bioreactors. The book also presents an in-depth review of the subject, from fundamental bench-scale research to industrial field applications related to the operation of full-scale systems successfully treating polluted air in Europe and the United States. Material dedicated to more conventional non-biological technologies has also been included, to provide a complete overview of the different alternative treatment processes. Audience: The different chapters have been written by international experts, as a result of a fruitful collaboration between European and American scientists and engineers. The resulting text is a high quality, valuable reference tool for a variety of readers, including graduate and postgraduate students, researchers, professors, engineers, and those professionals who are interested in environmental engineering and, more specifically, in innovative air pollution control technologies.

Download or read book Influence of Water Content, Concentration, and Nutrient Addition on the Biofiltration of Toluene for Air Pollution Mitigation Using Soil Biofilters with Water Content Control written by Daisy B. Badilla and published by GRIN Verlag. This book was released on 2024-02-20 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2011 in the subject Environmental Sciences, grade: Passed, University of the Philippines, course: Doctor of Philosophy in Environmental Engineering, language: English, abstract: In this study, the influence of water content on biofiltration performance was investigated. A biofilter reactor with water content control through changes in matric potential in a suction cell was used to treat toluene-contaminated air with soil as the filter bed medium. Results suggest the soil water content should be controlled at about 96% (dry weight) or a matric potential of -10 cm H2O. The maximum elimination capacity in this study appears to be a restricted to a narrow water content and this narrow range impacts on the operation of full-scale biofilters as traditional techniques for water content control would make maintaining this range difficult. Biofiltration, which is also sometimes referred to as bio-oxidation, is a method of air pollution control where contaminants in a gas stream are metabolized by microorganisms and converted to water, carbon dioxide and biomass. Biofiltration involves biological, chemical, and physical processes. It is often preferred over other air pollution control technologies since it does not produce secondary pollutants and does not involve expensive maintenance and operating costs. However, one of its disadvantages is the difficulty in controlling water content. A water retention curve of the soil was generated by plotting water content versus matric potential with data obtained using the suction cell. Two additional factors, concentration and nutrient addition, were investigated using two other soil biofilters. Improved biofiltration performance was observed at higher toluene concentrations. High toluene concentrations may be advisable during start-up as it converts microorganisms that do not thrive on toluene into nutrients for desired degraders inducing growth and improved performance but would have to be controlled to avoid excessive growth. In the membrane biofilter, the large pores in the biofilm contributed to a possible enhancement of pollutant and oxygen mass transfer. Nutrient addition improved the volumetric removal rate of toluene which implies that available nutrient has been limited. Nitrogen was identified as limiting the biomass growth. The production of carbon dioxide confirmed effective biodegradation of toluene in the soil biofilter. This study contributes to existing knowledge relevant conclusions and recommendations that may guide biofiltration operation, broaden concepts, or direct future studies and it considers treatment of indoor air pollution as a particular area of application.

Download or read book Indoor Air Pollution Control Using a Soil Biofilter written by Daisy Badilla and published by GRIN Verlag. This book was released on 2024-04-15 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2008 in the subject Physics - Biophysics, , language: English, abstract: Biofiltration may be used to control indoor air pollution. In biofiltration, contaminants in a gas stream are degraded by microorganisms and converted to carbon dioxide, water, and biomass. In this study, the CO2 production and the elimination capacity (EC) of toluene at inlet concentrations between 20 and 80 ppm were investigated using three biofilters operated separately with soil as bed material. Results showed soil, with its rich microflora taken to full advantage without inoculants and additional nutrients, biodegraded toluene at removal rates comparable to those in other studies at higher concentrations. The quantity of CO2 produced correlates with the quantity of toluene removed which implies effective biodegradation and suggests stable long-term operation at these low concentrations. Though the concentrations used in this study are not typical toluene indoor concentrations (ppb), results show biofiltration may be effective for indoor air pollution control with proper design considering biomass growth or biofilm structure, concentration, and gas flow rate.
