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.
Book Synopsis Influence of Water Content, Concentration, and Nutrient Addition on the Biofiltration of Toluene for Air Pollution Mitigation Using Soil Biofilters with Water Content Control by : Daisy B. Badilla
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.

Book Synopsis Biofilter for the purification of air contaminated with triethylamine (TEA) by : Venu Gopal
Download or read book Biofilter for the purification of air contaminated with triethylamine (TEA) written by Venu Gopal and published by GRIN Verlag. 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.

Book Synopsis Modeling and Evaluation of Pollutant Emissions from Industrial Biofilters by Dispersion Models by : Nada Azlah
Download or read book Modeling and Evaluation of Pollutant Emissions from Industrial Biofilters by Dispersion Models written by Nada Azlah and published by . This book was released on 2014 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: With gradually increasing strict environmental regulations that control emissions of volatile organic compounds (VOCs), reduced sulphur compounds and nuisance odors from industries, there is a growing need for air pollution control systems. Biofiltration systems have been widely used in the treatment of odorous and toxic volatile organic compounds. As compared to traditional physical and chemical systems, biofilteration is cost-effective, environmentally friendly, and highly efficient for many biodegradable pollutants. The biofilter concept is about using microorganisms to metabolize the variety of contaminants such as volatile organic compounds, reduced sulphur compounds and hydrocarbons. Although the biofilters are designed to eliminate pollutants with greater than 90% efficiency, accidental releases do occur due to biofilter failures; hence, this poses serious threats to health, especially to those who live in the vicinity of biofilter locations. This research investigates the dispersion of air pollutants that are accidentally released from industrial biofilters. Two commercial biofilters that were installed in different industrial sites, located in (Hickson) and (Toronto), Ontario, Canada, were used as test cases. A mathematical (Gaussian) dispersion model, a screening model (SCREEN3), and a non-steady state Lagrangian California Puff Model (CALPUFF), were used at different biofilter removal efficiencies to predict pollutant concentrations, dispersion and health effects, and to examine the impacts of topographical and meteorological conditions on concentration of pollutant emissions at receptor locations. The study shows that geographical variations (i.e., flat versus elevated surfaces) of the location of a biofilter have an effect on the wind, and hence on pollutant dispersion. The results confirmed that the iii wind direction has a direct impact on the pollutant plume path, whereas the wind speed and atmospheric stability class influence the pollutant concentration. The results elucidated that the high concentration of pollutants due to low removal efficiency of a biofilter can cause serious health problems. The results of this work can be used as a basis to evaluate biofilter performance under various atmospheric and geographical conditions and to improve biofilter design.
