Available in PDF, EPUB and Kindle. Book excerpt: This book combines the results of current research with essential background material to provide complete, in-depth coverage of every aspect of in situ and ex situ bioremediation, as well as an extensive overview of the physical and chemical processes currently available for treating petroleum-contaminated soils. Critical information has been collected and assembled under one cover to provide a convenient reference for anyone who must contend with this worldwide problem. Remediation of Petroleum Contaminated Soils: Biological, Physical, and Chemical Processes describes how to optimize the biodegradation of petroleum hydrocarbons in soil-water systems. It reports on the susceptibility of various petroleum components to biodegradation by microorganisms, and considers all groups of microorganisms for their potential contributions. The book also deals with problem areas such as the transport of organisms, oxygen, or nutrients throughout the subsurface, as well as biodegradation of polynuclear aromatic hydrocarbons (PAHs) and nonaqueous phase liquids (NAPLs). In addition, the book presents a variety of methods for monitoring bioremediation. This reference discusses current soil remediation processes and includes many innovative approaches. It also investigates means of controlling volatile organic compounds (VOCs) and leachate, and addresses methods for collecting and treating these secondary waste streams. The expansive coverage of this book will furnish readers with a wide range of options for developing treatment strategies and for customizing procedures for specific requirements.

Download or read book Enhanced Bioremediation of a Soil Contaminated with Both Petroleum Hydrocarbons and Heavy Metals with In soil Biosurfactant Production written by Faramarz Jalali and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils that are co-contaminated with petroleum hydrocarbons and metals account for 55% of all hazardous waste sites and are hard to decontaminate because of the different nature of the remedial treatment required. Biosurfactant-producing microorganisms are present in many environments and can be stimulated to produce them under favorable conditions. This dissertation investigates the effect of biosurfactant production by indigenous microorganisms of a co-contaminated soil. A soil that was heavily contaminated with petroleum hydrocarbons and metals was acquired from the Toronto Harbour area. Phase one of the study evaluated the extent of the biodegradation of organic pollutants as well as the feasibility of biosurfactant production by the produced microorganisms. Results show that by the end of the experiment (50 days) batches amended with nutrients produced biosurfactants up to 3 times their critical micelle concentration (CMC). The produced surfactants caused the concentration of TPH and metals in the filtrate to increase from 2 to 8% and from 2 to 4%, respectively. In the phase two of the experiments the production of biosurfactants was enhanced by 40% by limiting the inorganic source of nitrogen in the batches, following a short growth phase. The produced biosurfactants were able to wash 10% of TPH and 6% of the metal content of the soil. The results indicate that biosurfactants can be produced by the indigenous soil microorganisms using organic contaminants as the sole carbon source. Furthermore, the produced biosurfactants showed potential to enhance biodegradation of petroleum hydrocarbons as well as to improve flushing of the remaining soil pollutant from soil.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Soils contaminated with petroleum hydrocarbons, like those that resulted from the Lac Mégantic disaster, are often treated using cost-effective bioremediation technologies such as biopiles. As the soil undergoes aging, the contaminants become more resistant to mass transfer, remediation slows, and residual hydrocarbon fractions remain in the soil. Biosurfactants are sometimes added to increase bioavailability to soil microbes for enhanced bioremediation performance. These surface active compounds produced by microorganisms are able to improve the solubilisation, mobilization, and emulsification of hydrophobic or insoluble organic contaminants. However, although positive biosurfactant influence is often reported, there have been numerous cases where no or negative effects were observed. Limited information is currently available on the biosurfactant inhibition of biodegradation - the phenomenon is not well understood. It is likely linked to interaction of the biosurfactant in question with the microbial community and the hydrocarbon degraders. Studies investigating microbial interactions with biosurfactants typically use an uncontaminated soil sample spiked with fresh hydrocarbons rather than aged and weathered hydrocarbon-contaminated soils. This study investigated the effects of selected biosurfactants on microbial community dynamics as well as hydrocarbon biodegradation in aged hydrocarbon contaminated biopile soils from Lac Mégantic. One biopile soil demonstrated a significant reduction in total petroleum hydrocarbons (TPH) for biosurfactant treated systems after 34 days, but no significant difference between nutrient amended and unamended systems. Another biopile soil over a longer period of 80 days meanwhile found that the amended system demonstrated high TPH reduction, with one of the best overall reduction trends. The low to medium biosurfactant (rhamnolipid) doses had comparable performances to the amended system. A high rhamnolipid dose reduced the biodegradation extent to the same low level as unamended controls. The different results between the soils, as well as between the different biosurfactant doses, were most likely due to the biosurfactant influence on the microbial community during the process of biodegradation. Analysis of the microbial community indicated changes in community composition with biosurfactant dose. The Proteobacteria phyla dominated overall throughout the 80 days, though the Gamma subclass tended to increase early and then decrease as biodegradation plateaued. Generally, with a few exceptions, higher microbial diversity was found in the better performing TPH reducing systems. The Alpha subclass seemed to become enriched and increased in relative abundance with higher rhamnolipid doses. Experiments on pure cultures isolated from the same soil provided evidence of hydrocarbon degraders using the rhamnolipids as a carbon source, suggesting the possibility of potential preferential degradation of biosurfactants over residual hydrocarbons in the weathered soils." --

This book was released on 2008-02-21 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide to bioremediation in cold regions is designed to aid environmental practitioners, industry, and regulators in the remediation of petroleum spills and contaminated sites in cold regions. Remediation design and technology used in temperate climates does not necessarily work in cold climates, and cleanup takes longer due to shorter treatment seasons, sub-freezing temperatures, ground freezing and thawing, and limited bioactivity. Environmental engineers and scientists from eight countries working in the polar regions combine their experiences and expertise with petroleum contamination to write this book. It contains in-depth discussions on regulations, freezing and frozen ground, identification and adaptations of cold-tolerant bacteria, contaminant transport in cold soils and permafrost, temperature effects on biodegradation, analytical methods, treatability studies, and nutritional requirements for bioremediation. Emphasis is given to practical and effective bioremediation methods for application in cold regions. Emerging technologies are also discussed.

Download or read book Total Petroleum Hydrocarbons written by Saranya Kuppusamy and published by Springer. This book was released on 2019-08-13 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “total petroleum hydrocarbons” (TPHs) is used for any mixture of several hundred hydrocarbons found in crude oil, and they represent the sum of volatile petroleum hydrocarbons and extractable petroleum hydrocarbons. The petrol-range organics include hydrocarbons from C6 to C10, while diesel-range organics are C10-C28 hydrocarbons. Environmental pollution by petroleum hydrocarbons is one of the major global concerns, particularly in oil-yielding countries. In fact, there are more than five million potentially contaminated areas worldwide that represent, in general, a lost economic opportunity and a threat to the health and well-being of humans and the environment. Petroleum-contaminated sites constitute almost one-third of the total sites polluted with chemicals around the globe. The land contamination caused by industrialization was recognized as early as the 1960s, but less than a tenth of potentially contaminated lands have been remediated due to the nature of the contamination, cost, technical impracticability, and insufficient land legislation and enforcement. This book is the first single source that provides comprehensive information on the different aspects of TPHs, such as sources and range of products, methods of analysis, fate and bioavailability, ecological implications including impact on human health, potential approaches for bioremediation such as risk-based remediation, and regulatory assessment procedures for TPH-contaminated sites. As such, it is a valuable resource for researchers, graduate students, technicians in the oil industry and remediation practitioners, as well as policy makers.

Available in PDF, EPUB and Kindle. Book excerpt: In the process of Savannah River Site (SRS) operations limited amounts of waste are generated containing petroleum, and radiological contaminated soils. Currently, this combination of radiological and petroleum contaminated waste does not have an immediate disposal route and is being stored in low activity vaults. SRS developed and implemented a successful plan for clean up of the petroleum portion of the soils in situ using simple, inexpensive, bioreactor technology. Treatment in a bioreactor removes the petroleum contamination from the soil without spreading radiological contamination to the environment. This bioreactor uses the bioventing process and bioaugmentation or the addition of the select hydrocarbon degrading bacteria. Oxygen is usually the initial rate-limiting factor in the biodegradation of petroleum hydrocarbons. Using the bioventing process allowed control of the supply of nutrients and moisture based on petroleum contamination concentrations and soil type. The results of this work have proven to be a safe and cost-effective means of cleaning up low level radiological and petroleum-contaminated soil. Many of the other elements of the bioreactor design were developed or enhanced during the demonstration of a ''biopile'' to treat the soils beneath a Polish oil refinery's waste disposal lagoons. Aerobic microorganisms were isolated from the aged refinery's acidic sludge contaminated with polycyclic aromatic hydrocarbons (PAHs). Twelve hydrocarbon-degrading bacteria were isolated from the sludge. The predominant PAH degraders were tentatively identified as Achromobacter, Pseudomonas Burkholderia, and Sphingomonas spp. Several Ralstonia spp were also isolated that produce biosurfactants. Biosurfactants can enhance bioremediation by increasing the bioavailability of hydrophobic contaminants including hydrocarbons. The results indicated that the diversity of acid-tolerant PAH-degrading microorganisms in acidic oil wastes may be much greater than previously demonstrated and they have numerous applications to environmental restoration. Twelve of the isolates were subsequently added to the bioreactor to enhance bioremediation. In this study we showed that a bioreactor could be bioaugmented with select bacteria to enhance bioremediation of petroleum-contaminated soils under radiological conditions.
