Book excerpt: The objective of the project was to develop in the laboratory, and test in the field, a biological water treatment process for treating perchlorate-contaminated water. Bench- scale experiments were conducted on three processes: a packed bed reactor amended with soluble substrates (acetate); a hydrogen gas fed four-phase unsaturated trickle-type packed column; and a membrane-immobilized biofilm reactor. Based on these tests, one reactor system, an acetate-fed packed bed reactor (PSU-O4 system), was selected for further testing in pilot-plant tests at the Texas Street well field in Redlands, California. All three systems successfully removed perchlorate at rates sufficient to achieve an acceptable level of perchlorate removal for subsequent treatment for potable use. Pilot- scale tests at the Redlands site in California showed that perchlorate could be removed to non-detectable levels (

Book excerpt: Ion exchange materials are extremely effective absorbents generally containing some functional groups with insoluble structures, which have high affinity capacities towards the targets among a series of structurally similar ions or ion groups. In recent decades, the various methods used to preparing the absorbents for contaminant removal and resource recycle from environment have been extensively studied under the backgrounds of environment pollution and resource shortages. Molecular imprinting technology (MIT) was developed rapidly as a research hot topic to prepare ion exchange materials with shape memory effects. In consideration of the advantages of molecular imprinted polymers (MIPs), including high adsorption capacities, high selectivity, easy recycle etc., their applications in the separation and concentration of target molecules or ions have been widely explored. This book briefly narrates the fundamentals and preparations of MIPs, and particularly focus on the research advances relevant to human-living environment including water, atmosphere and soil. An overview of the most important applications of the ion exchange method in the treatment of industrial wastewaters which contain heavy metal ions, and the main environmental benefits of this method are highlighted. The most important ion exchangers used in environment remediation processes, including their classification and environmental utilisations, are presented as well. The influence of operating conditions on the ion exchange process is discussed, both from efficiency and mechanism perspectives. Also, the opportunities and challenges, which make that the ion exchange method to be still an important research issue at international level, are reviewed. Other chapters familiarise the reader with innovative practices to develop sustainable water treatment methods; review the use of adsorption materials, including raw biomasses, and ion exchange resins for the treatment of olive mill wastewater; various examples of selective removal of heavy metal ions discharged in an effluent from electroplating plants, metal finishing operations, as well as mining and electronics industries through ion exchange are presented and finally; the principal mechanisms and specific features of the copper ion exchange in alkali silicate glasses is explored.

Book excerpt: The development of analytical methods for identifying widespread perchlorate contamination brought about an explosion of research into the environmental problems and their potential solutions along with a corresponding increase in the availability of information. Unlike reference works that focus on only a few aspects of this contaminant, Perchlorate: Environmental Problems and Solutions offers a comprehensive, single source of information on perchlorate contamination in the environment. Summarizing the state of the science and developments in engineering, the book describes: Common sources of perchlorate Its behavior in the environment Methods for analyzing perchlorate in environmental samples Potential risks to human health and the environment Regulatory standards and criteria Techniques for remediating environmental contamination The authors illustrate these points with case studies of perchlorate contamination in soil, groundwater, and surface water. These case studies provide perspective on issues commonly faced by scientists, engineers, and managers of perchlorate-impacted sites. Organized to follow the logical sequence of identifying and solving contamination problems, the book provides the foundation necessary to understand perchlorate's occurrence, environmental behavior, regulatory status, and remediation.

This book was released on 2008-12-02 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1970s and early 1980s, our nation began to grapple with the legacy of past disposal practices for toxic chemicals. With the passage in 1980 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, it became the law of the land to remediate these sites. The U. S. Department of Defense (DoD), the nation’s largest industrial organization, also recognized that it too had a legacy of contaminated sites. Historic operations at Army, Navy, Air Force, and Marine Corps facilities, ranges, manufacturing sites, shipyards, and depots had resulted in widespread contamination of soil, groundwater, and sediment. While Superfund began in 1980 to focus on remediation of heavily contaminated sites largely abandoned or neglected by the private sector, the DoD had already initiated its Installation Restoration Program in the mid 1970s. In 1984, the DoD began the Defense Environmental Restoration Program (DERP) for contaminated site assessment and remediation. Two years later, the U. S. Congress codified the DERP and directed the Secretary of Defense to carry out a concurrent program of research, development, and demonstration of innovative remediation technologies. As chronicled in the 1994 National Research Council report, “Ranking Hazardous-Waste Sites for Remedial Action”, our early estimates on the cost and suitability of existing technologies for cleaning up contaminated sites were wildly optimistic. Original estimates, in 1980, projected an average Superfund cleanup cost of a mere $3.

Available in PDF, EPUB and Kindle. Book excerpt: The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater treatment is unique. Removing the sources of contamination, as we did when we cleaned a river or lake, is only the first step. A groundwater remediation must include cleaning of the body of water itself, the aquifer. The revised and updated edition of Groundwater Treatment Technology provides a complete review of the technologies developed over the past 10 years for groundwater treatment. It also explains the design techniques that are required to apply those technologies successfully in a groundwater cleanup. Featured areas of coverage include: Specific design methods for the various technologies that are merely described in other publications Physical/chemical and treatability properties of 30 organic compounds that are most often encountered in groundwater situations Detailed strategies for remediation New biological treatment methods Specific data on treatment methods as applied in the field Practical suggestions on applications of technologies for groundwater treatment Drawing on his experience as a designer of over 100 groundwater treatment systems, Evan K. Nyer starts by showing how to develop the data necessary to define what type of treatment is necessary. He then explains how groundwater treatment is unique. Nyer follows with expert accounts of specific treatment technologies. Physical/chemical organic methods such as air stripping, carbon adsorption, and pure compound removal are explored in detail. In addition, new techniques including UV Oxidation and other emerging technologies are explained and directly related to groundwater design situations. An entire chapter is devoted to biological methods, one of the most promising areas for organic groundwater treatment. There is also comprehensive coverage of inorganic methods, that addresses everything from precipitation to solids/liquid separation and advanced ion removal methods. This definitive sourcebook also contains helpful cost factor analyses, plus representative case histories showing how the techniques of groundwater treatment have been applied in the field. Wide-ranging, authoritative, and completely updated, the Second Edition of Groundwater Treatment Technology is essential reading for wastewater engineers, industrial managers, hydrologists, soil experts, government officials, and environmental lawyers who want to keep abreast of the latest developments in this important field.
