Bioremediation of Nitroaromatic and Haloaromatic Compounds
Sites contaminated with explosive compounds, pesticides, herbicides, PCBs, and other aromatic compounds present formidable technical, regulatory, and financial challenges. The application of bioremediation technologies to such sites offers the promise of cost-effective site remediation that can serve as a key component of a well-formulated strategy for achieving site closure. This volume presents the results of bench-, pilot-, and field-scale projects focused on the use of biological approaches to remediating problem compounds, such as RDX, HMX, TNT, DDT, 2, 4-D, nitro- and chlorobenzenes, nitroaniline, chloroaniline, hexachlorobenzene, PCPs, PCBs, and dichlorophenol in soils and groundwater.
In Situ Bioremediation of Petroleum Hydrocarbon and Other Organic Compounds
From supertanker oil spills to leaking underground storage tanks, contamination from petroleum hydrocarbon fuels and other organic compounds is a problem throughout the world. A considerable body of experience has been built up over the past two decades in applying in situ bioremediation to a variety of contaminants in all media. This volume provides a comprehensive guide to the latest technological breakthroughs in both the laboratory and the field, covering such topics as air sparging, cometabolic biodegradation, treatment of MTBE, real-time control systems, nutrient addition, rapid biosensor analysis, multiphase extraction, and accelerated bioremediation.
Engineered Approaches for in Situ Bioremediation of Chlorinated Solvent Contamination
Sites contaminated with chlorinated compounds pose health risks and are challenging and often expensive to treat in the field. This volume brings together the most up-to-date laboratory findings and the latest full-scale results from bioremediation efforts at actual field sites. Engineering approaches discussed include biobarriers, cometabolism, bioaugmentation, in situ oxidation, Fenton's Reagent, in situ bioremediation, and more.
Bioreactor and Ex Situ Biological Treatment Technologies
Many site-and wastestream-remediation challenges are best met by applying bioreactors and other ex situ treatment technologies, either singly or sometimes in combination with other technologies. Such engineered systems for the treatment of vapor, water, slurries, and soils are the focus of this volume, which covers a number of treatment technologies such as slurry reactors, compost reactors, biopiles, packed-bed reactors, vapor-phase reactors, and biofilters. Articles cover a number of technologies and media, as well as a wide variety of contaminants, among them arsenic, TPHs, MTBE, heavy metals, solvents, and other wastes.
Natural Attenuation of Chlorinated Solvents, Petroleum Hydrocarbons, and Other Organic Compounds
Natural attenuation was first demonstrated at sites with hydrocarbon contamination, but recent studies at sites contaminated by chlorinated compounds have shown that this approach often has merit for these more challenging contamination problems. This volume covers natural attenuation in media ranging from deep aquifers to shallow soils, and for contaminants ranging from fuels to solvents to herbicides, and offers the reader a comprehensive overview of case studies that represent the state of the art in natural attenuation approaches to site remediation.
Bioremediation of Metals and Inorganic Compounds
Unlike organic contaminants, which often can be broken down by biological processes into relatively harmless metabolites and by-products, metals are elemental and often have an inhibitory effect on biological activity. Despite these potential pitfalls, there has been progress recently in applying bioremediation technologies to metals and inorganics. This volume encompasses topics such as lead solubility reduction, chromium reduction, denitrification, volatilization of selenium in soils, metals recovery from acid mine drainage, and even the possibility of applying artificial neural network technology to aid in bioremediation.
Phytoremediation and Innovative Strategies for Specialized Remedial Applications
From laboratory studies on plant uptake to full-scale phytoremediation treatment strategies, this volume covers the use of plants to treat contaminants such as hydrocarbons, metals, pesticides, perchlorate, and chlorinated solvents. In addition to the phytoremediation studies, this volume also covers specialized remediation approaches such as sequential anaerobic/aerobic in situ treatment, membrane bioreactors, and Fenton's reagent oxidation.
Advanced Biological Processes for Wastewater Treatment
This book presents recent developments in advanced biological treatment technologies that are attracting increasing attention or that have a high potential for large-scale application in the near future. It also explores the fundamental principles as well as the applicability of the engineered bioreactors in detail. It describes two of the emerging technologies: membrane bioreactors (MBR) and moving bed biofilm reactors (MBBR), both of which are finding increasing application worldwide thanks to their compactness and high efficiency. It also includes a chapter dedicated to aerobic granular sludge (AGS) technology, and discusses the main features and applications of this promising process, wh...
