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.

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.

This book was released on 2006-03-31 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts intensify to decrease the presence of disease-causing microorganisms and disinfection by-products in drinking water, to minimize microbial regrowth potential in distribution systems, and where operator skill levels are emphasized. Recent Progress in Slow Sand and Alternative Biofiltration Processes provides a state-of-the-art assessment on a variety of biofiltration systems from studies conducted around the world. The authors collectively represent a perspective from 23 countries and include academics, biofiltration system users, designers, and manufacturers. It provides an up-to-date perspective on the physical, chemical, biological, and operational factors affecting the performance of slow sand filtration (SSF), riverbank filtration (RBF), soil-aquifer treatment (SAT), and biological activated carbon (BAC) processes. The main themes are: comparable overviews of biofiltration systems; slow sand filtration process behavior, treatment performance and process developments; and alternative biofiltration process behaviors, treatment performances, and process developments.

Book excerpt: The best papers from the three-day conference on Safe Drinking Water from Source to Tap June 2009 in Maastricht are published in this book covering the themes of challenges of the water sector and adaptive strategies, treatment, distribution, risk assessment and risk management, sensors and monitoring, small scale systems, simulation, alternative water supply & sources, consumer involvement, and future drinking water. Worldwide, the water supply sector is facing tremendous challenges. Every new emerging contaminants and pathogens and aging infrastructures that are vulnerable for deliberate contamination pose a threat to the quality of water supplies. Shortage of good quality and readily treatable resources is increasing due to global warming, urbanisation and pollution from agriculture and industry. Regulators and consumers are becoming more demanding. Techneau - the largest European project on drinking water - addresses these challenges by developing adaptive supply system options and new and improved treatment and monitoring technologies. Future system options to be studied are flexible, small scale and multi-source supplies, utilising non conventional resources like brackish ground water, treated wastewater and urban groundwater.

Book excerpt: The filamentous fungi are perhaps unique in the diversity of their metabolic activities. This includes biosynthetic as well as degradative activities, many is to provide an of which are of industrial interest. The objective of this text up-to-date and broad review which emphasizes the genetic and molecular biological contribution in the field of fungal biotechnology. This text begins with an overview of the tools and methodologies involved which, to a large extent, have been developed in the model filamentous fungus Aspergillus nidulans and subsequently have been extended to commercially important fungi. This is followed by a chapter which provides a compilation of genes isolated from commercial fungi and their present status with respect to structure, function and regulation. Chapters 3 and 4 highlight the degradative powers of filamentous fungi. First, a discussion of what is known regarding the molecular genetics of fungi and the genes and enzymes involved in the beverage and food industries. This has an oriental flavour, reflecting the tremendous importance of fungi in traditional Chinese and Japanese food production. An account of lignocellulose degradation by filamentous fungi follows, illustrating the potential of fungi to utilize this substance as a renewable energy source. The ability of fungi to produce high-value foreign proteins is reviewed in chapters 5 and 6. Chymosin production, in particular, represents a good example of high-level yields being obtained, such as to warrant commercial production.

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.
