Download or read book Sustainable Heavy Metal Remediation written by Eldon R. Rene and published by Springer. This book was released on 2017-07-24 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the principles, underlying mechanisms, thermodynamic functions, kinetics and modeling aspects of sustainable technologies, particularly from the standpoint of applying physical, chemical and biological processes for the treatment of wastewater polluted with heavy metals. Particular emphasis has been given to technologies that are based on adsorption, electro-coagulation, bio-precipitation, bio-solubilization, phytoremediation and microbial electrolysis. Metal contamination in the environment is one of the persisting global issues. The adverse health effects of heavy metals on human beings and its impact on the environment has been well-documented. Several physico-chemical and biological technologies have been successfully implemented to prevent and control the discharge of industrial heavy metal emissions. On the contrary, metal resource depletion has also accelerated dramatically during the 20th century due to rapid advances in industrial engineering and medical sciences, which requires large amount of raw materials. To meet the global metal demand, in recent years, novel research lines have started to focus on the recovery of metals from metal contaminated waste streams. In order to conflate both metal removal and recovery, new technologies have been successfully tested, both at the lab and pilot-scale. The target audience of this book primarily comprises of research experts, practicing engineers in the field of environmental/chemical technology and graduate students.

Download or read book Microbial Metabolism of Metals and Metalloids written by Christon J. Hurst and published by Springer Nature. This book was released on 2022-04-24 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the metabolic processes by which microbes obtain and control the intracellular availability of their required metal and metalloid ions. The book also describes how intracellular concentrations of unwanted metal and metalloid ions successfully are limited. Its authors additionally provide information about the ways that microbes derive metabolic energy by changing the charge states of metal and metalloid ions. Part one of this book provides an introduction to microbes, metals and metalloids. It also helps our readers to understand the chemical constraints for transition metal cation allocation. Part two explains the basic processes which microbes use for metal transport. That section also explains the uses, as well as the challenges, associated with metal-based antimicrobials. Part three gives our readers an understanding that because of microbial capabilities to process metals and metalloids, the microbes have become our best tools for accomplishing many jobs. Their applications in chemical technology include the design of microbial consortia for use in bioleaching processes that recover metal and metalloid ions from industrial wastes. Many biological engineering tasks, including the synthesis of metal nanoparticles and similar metalloid structures, also are ideally suited for the microbes. Part four describes unique attributes associated with the microbiology of these elements, progressing through the alphabet from antimony and arsenic to zinc.

Download or read book Unit Operations in Environmental Engineering written by Robert Noyes and published by William Andrew. This book was released on 1994-12-31 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the practical aspects of environmental technology organized into eight chapters relating to unit operations as follows: 1. Biological Technology 2. Chemical Technology 3. Containment and Barrier Technology 4. Immobilization Technology 5. Membrane Technology 6. Physical Technology 7. Radiation and Electrical Technology 8. Thermal Destruction Technology Traditional technologies have been included, as well as those that can be considered innovative and emerging. The traditional approaches have been the most successful, as contractors are careful about bidding on some of the newer technologies. However, as regulatory requirements increase, markets will open for the innovative and emerging processes. There will be increasing pressure to break down complex waste streams, with each subsequent stream demanding separate treatment. In addition, a number of technologies have been developed by combining processes directly, or in a treatment train, and these developments are expected to assume increasing importance. However, such concerns as uncertainties due to liability, regulatory approval, price competition, and client approval have limited the application of some of these newer technologies.

Download or read book Emerging Technology for Bioremediation of Metals written by Battelle Memorial In and published by CRC Press. This book was released on 1994-02-16 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioremediation techniques for treating metals-contaminated soil and water are in an emerging state of development. Unlike organic compounds that can be broken down into harmless compounds such as CO2 and water, metals and their salts generally inhibit biological activity. They must be converted into more complex states, be sorbed, or undergo valence state changes before biodegradation by activated sludge treatment or other complex reactions such as air stripping can occur. This book introduces various treatment technologies and options for the bioremediation of metals. The chapters, written by researchers and practitioners from North America and Europe, represent the most recent compilation of state-of-the-art techniques and methods for metals biotreatment. These topics and more are addressed:

Download or read book The Importance of Chemical Speciation in Environmental Processes written by M. Bernhard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report, the editors replaced the term "speciation" wherever it occurred by "identification and quantification," or "description of abundance," or "reactivity," or "transformation" of a chemical species, according to whichever one of the four meanings the author had evidently meant to convey. In line with the Dahlem Workshop Model, this Report comprises the background papers written in advance of the meeting on the current status of problems in environmental research and on advanced analytical tech niques for the identification and quantification of chemical species, as well as the group reports summarizing the results of the discussions held during the meeting. Each group report was prepared during the meeting by one "rapporteur" with the help of members of that group and finalized by the rapporteur (listed as the first author of the group report) after the meeting, taking into account both verbal comments made during the presentation of the reports in the plenary session at the end of the workshop and written comments received afterwards.
