This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic Aromatic Hydrocarbon (PAH)-contaminated soils are a great environmental and public health concern nowadays. Aerobic soil-slurry bioreactor technology has emerged as an effective and feasible technique with a high remediation potential, especially for the fine soil fractions, which often contain the highest pollution levels and are hard to treat with conventional approaches. However, the mechanisms involved in the PAH removal in the bioreactor are still not completely understood. In addition to the biological processes, important mass transfer mechanisms need to be considered (gas-liquid oxygen mass transfer, sorption-desorption, volatilization, etc.). For this study, a mechanistic approach was developed, in which the bioslurry process was deconstructed using a model system. Each part was isolated and analyzed individually. Then, the global process was studied and the results of the analysis of the individual parts were used to understand the global bioremediation treatment. Among the results obtained, it was demonstrated that clay presence in soils can strongly affect oxygen transfer in slurry systems, the pollutant bioavailability was limited by the desorption process, particularly when organic matter was present in the soil and volatilization can be the major removal process during the lag phase period in biodegradation. The results of this research work can be extrapolated to the study of real contaminated soil remediation. The mechanistic approach can be used as a generic method to investigate the slurry bioreactor treatment for any type of soil, different pollutants and microbial communities, and other operating conditions.

This book was released on 2004-06-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The huge expansion of the chemical and petroleum industries in the twentieth century has resulted in the production of a vast array of chem ical compounds and materials that have transformed our lives. The associated large-scale manufacturing, processing and handling activi ties have caused a serious deterioration in environmental quality and created threats to human health. These negative impacts have led to responses and regulations requiring remedial action in support of envi ronmental sustainability. of biotechnological methods through bioremediation, Application has gained prominence as an option for soil remediation methods. Bioremediation is a multidisciplinary approach where biologists, chem ists, soil scientists and engineers work as team to develop and imple ment remediation processes. Bioremediation has now been used successfully to remediate many petroleum-contaminated sites. However, there are as yet no commercial technologies commonly used to reme diate the most recalcitrant contaminants. Nevertheless, bioremediation is a rapidly advancing field and new bio-based remedial technologies are continuing to emerge.

This book was released on 2015-05-11 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The necessity to find sound solutions for soil pollution is intensifying due to polycyclic aromatic hydrocarbons' (PAH) toxicity and hydrophobic nature. Most reported work utilised single treatment approach but combination of multiple techniques in bioremediation is scarce. This book presents a vermitechnology study on development of an innovative tri-layer treatment for PAHs contaminated soil. The treatment therefore, provides a new insight of an environmentally sound approach particularly for on-site solution. The analysis should help shed some light on this integrative solution and should be especially useful to professionals in Environmental Science and Engineering fields, or everyone else who may be considering bioremediation techniques.

Download or read book Bioremediation of Petroleum and Radiological Contaminated Soils at the Savannah River Site written by and published by . This book was released on 2004 with total page 5 pages. 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.
