Available in PDF, EPUB and Kindle. Book excerpt: Sediment contamination is a global environmental issue and there are no treatment technologies that can be readily applied except dredging, which is very expensive and time consuming. In this thesis, a computer model has been developed and applied to in-situ bioremediation of contaminated sediments. The mathematical model has been applied to experimental data that was obtained previously using a bench-scale system using sediments contaminated with polycyclic aromatic hydrocarbons (PAHs). The use of hollow fiber membranes offers advantages of cost-effectively supplying and controlling the availability of oxygen (air), nutrients or other electron acceptors, such as nitrate and sulfate to the contaminated sediments, without significant loss to the water column. The biokinetic and transport parameters in the mathematical model were fitted to the bench-scale experimental data to achieve a low average error between the experimental and model values. The fitted model was used to calculate the design of the hollow fiber system, such as distance between the fibers. The WASP-6 computer program, developed previously for calculating dissolved oxygen levels in natural water bodies, was used to simulate the impact of contaminated sediments and the effect of using the membrane system to preserve the dissolved oxygen levels. Results of this study have shown that controlled delivery of oxygen from air is a feasible technique to achieve accelerated bioremediation rates of PAH contaminated sediments and improved water quality in rivers and lakes adversely impacted by these contaminated sediments.

Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Download or read book Microbial Action on Hydrocarbons written by Vivek Kumar and published by Springer. This book was released on 2019-02-08 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses ways to overcome the side effects of using hydrocarbon-based products as energy sources. Hydrocarbons produce raw crude oil waste of around 600,000 metric tons per annum, with a range of uncertainty of 200,000 metric tons per year. The various chapters in this book focus on approaches to reduce these wastes through the application of potential microbes, in a process called bioremediation. The book is a one-stop reference resource on the methods, mechanisms and application of the bio-composites, in the laboratory and field. Focusing on resolving a very pressing environmental issue, it not only provides details of existing challenges, but also offers deeper insights into the possibility of solving problems using hydrocarbon bioremediation.

This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many areas of Eastern Europe have been polluted to an extent unknown in the West. Four such sites - Kola Peninsula, northern Bohemia, upper Vistula Basin, and Katowice - have been identified and detailed accounts of the pollution at these sites are given. The current status of the use of biomarkers in hazard assessment is given by several scientists from NATO countries. Four working groups, comprising scientists working on the polluted sites and western scientists with expertise in biomarkers, examine the use of biomarkers to assess the environmental health of each of these areas and make recommendations on the future direction of remedial action in these areas.

This book was released on 2018-10-12 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: With rampant industrialization, the management of waste generated by various industries is becoming a mammoth problem. Wastewater discharges from industrial and commercial sources may contain pollutants at levels that could affect the quality of receiving waters or interfere with potable water supplies. Thousands of small and large-scale industrial units dump their waste, which is often toxic and hazardous, in open spaces and nearby water sources. Over the last three decades, many cases of serious and permanent damage to the environment and human health on the part of these industries have come to the fore. This book mainly focuses on the biological treatment of wastewater from various industries, and provides detailed information on the sources and characteristics of this wastewater, followed by descriptions of the biological methods used to treat them. Individual chapters address the treatment of wastewater from pulp and paper mills; tanneries; distilleries, sugar mills; the dairy industry; wine industry; textile industry; pharmaceutical industry; food processing industry; oil refinery/petroleum industry; fertilizer industry and beverage/ soft drink bottling industry; and include the characteristics of wastewater, evaluation of biological treatment methods, and recycling of wastewater. Easy to follow, with simple explanations and a good framework for understanding the complex nature of biological wastewater treatment processes, the book will be instrumental to quickly understanding various aspects of the biological treatment of industrial wastewater. It will serve as a valuable reference book for scientists, researchers, educators, and engineers alike.
