Many human activities-and industrial production in particular-require enormous quantities of clean water and, at the same time, produce enormous quantities of wastes and pollution that require the development of major physical-chemical technologies, processes whose implementation and costs must be justified by the degree of treatment achieved. In Physicochemical Treatment Processes, Volume 3 of the Handbook of Environmental Engineering, a panel of practicing professional engineers and respected educators critically survey both the principles and practices involved in water pollution control, potable water treatment, water reuse, and sludge treatment. The authors discuss the performance, potential, and limitations of each major physicochemical treatment process in detail-including the physical and chemical theory behind it, the applications, the design procedures, examples, references, and cost data-as a basis for intelligent planning and realization of abatement systems. Among the processes covered are screening, comminution, flow equalization, neutralization, mixing, coagulation, flocculation, chemical precipitation, oxidation, recarbonization, softening, halogenation, and disinfection. Additional chapters discuss ozonation, electrolysis, sedimentation, dissolved air flotation, gravity filtration, granular activated carbon adsorption, and sludge treatment. The emphasis throughout is on developing the necessary engineering from fundamental principles of chemistry, physics, and mathematics. Two companion volumes, Air Pollution Control Engineering, Volume 1, and Advanced Air and Noise Pollution Control, Volume 2, survey the basic air pollution control techniques and the use of multiple techniques to deal with air, thermal, and noise pollution. Cutting-edge and highly practical, Physicochemical Treatment Processes, Volume 3 offers educators, students, and practicing engineers a strong grounding in the principles of this critical field, as well as effective methods for developing optimal physical-chemical technologies at costs that are fully justified by the degree of treatment achieved.

Environmental biotechnology, which was in its infancy in the early 80's, has evolved thanks to the revolution brought about by molecular biology. Multiple successes in the biological cleanup of civil and industrial wastewater and of hydrocarbon soil pollution, demonstrate the vast power of clean technologies. In addition, the buildup of information on the activities of microorganisms as catalysts in all sorts of natural, industrial and animal environments has flourished. There is a continuing realization of the critical role of microbial processes in biological, industrial and geological systems. Since environmental biotechnology has matured, it is ready to tackle bigger challenges: the scaling up of many bioremediation systems still in progress, the search for novel biocatalysts for industrial applications, the continuing effort against common human life-threatening processes such as antibiotic resistance, the accumulation of hormone-mimicking substances (endocrine disrupters), the deposition of air-borne pesticides in the environment and, the degradation of recalcitrant contaminants. These endeavors will help prevent the contamination of food chains, protect human life and allow for human activity and economic development that do not compromise environmental sustainabijity. This volume includes the key lectures and participants' contributions delivered at the NATO-funded Advanced Research Workshop (NATO- ARW No. 980838) Bioremediation of Soils Contaminated with Aromatic Compounds: Effects of Rhizosphere, Bioavailability, Gene Regulation and st rd Stress Adaptation, held in Tartu, Estonia, from the 1 to the 3 of July 2004, and attended by participants from 15 countries.

The book describes and assesses current concepts for long-term disposal of highly radioactive waste. Different types of rock are discussed and assessed with respect to practical difficulties in construction of a repository, and the efficiency in isolating radioactive waste. Safety matters are most important and are treated in the respective chapters and in a final, conclusive chapter. Cost issues and related quality matters are discussed for the case of constructing a virgin repository and repositories in the form of converted abandoned mines.

Contaminated sediments pose some of the most difficult site remediation issues. Contaminated sediments typically reside in spatially variable and dynamic systems subject to seasonal flow variations and episodic storm events. The volume of sediments that must be managed at particular sites often exceeds one million cubic meters, dwarfing many contaminated soil sites. These sediments are also associated with equally daunting volumes of water and efforts to remove the contamination typically entrains even more water. The environmental security of both NATO and partner countries is at risk due to the pervasive nature of sediment contamination of rivers, lakes and harbors. A NATO Advanced Research Workshop was convened in Bratislava in May 2005 to discuss current approaches to managing contaminated sediments and to identify research necessary to overcome outstanding problems. In this text, drawn from presentations and discussion of that workshop, current approaches to the assessment and remediation of contaminated sediments will be discussed with the emphasis on in-situ management. Physical, chemical and biological approaches for the assessment and remediation of sediments are all addressed. Developing regulatory and strategic approaches are highlighted with a special emphasis on the potential for biological remediation for the management of contaminated sediments.

Recent investigations have highlighted the similarities between turbulence in cryogenic fluids at temperatures close to absolute zero, in particular superfluid helium, and turbulence in ordinary fluids. This book contains lectures on various theoretical and experimental aspects of the problem given by experts at the advanced school “Vortices and Turbulence at Low Temperatures” held at CISM, Udine, in the summer of 2007. The lectures provide an introduction into this rapidly expanding area of research. The book is suitable to PhD students and young researchers starting their career as well as established researchers in either low temperature physics or fluid mechanics who are interested in this problem.
