Environmental Separation of Heavy Metals


Book Description

This new book explains advanced and emerging technologies for removing heavy metals from wastestreams and contaminated sites. Separation processes of this type are critical for meeting stringent regulations of priority pollutants, especially arsenic, mercury, and lead, which the text treats in depth. After explaining the chemistry of heavy metals and their transport in various media, the work offers a comprehensive analysis of strategies for separating metals from groundwater, wastewater, contaminated soils, and industrial sludges. Both the basics and the applications of techniques such as ion-exchange, specialized sorbents, novel membranes, advanced precipitates, and electrokinetic processes are presented with a view to current use and potential for future applications such as resource reuse. Information in this volume enables engineers and other investigators to adapt and select the best means to remove and, in certain instances, recover heavy metals.




New Trends in Removal of Heavy Metals from Industrial Wastewater

Biosorption of Heavy Metals


Book Description

This state-of-the-art volume represents the first comprehensively written book which focuses on the new field of biosorption. This fascinating work conveys essential fundamental information and outlines the perspectives of biosorption. It summarizes the metal-sorbing properties of nonliving bacterial, fungal, and algal biomass, plus highlights relevant metal-binding mechanisms. This volume also discusses the aspects of obtaining and processing microbial biomass and metal-chelating chemicals into industrially applicable biosorbent products. Microbiologists, chemists, and engineers with an interest in new technological and scientific horizons will find this reference indispensable.







Biosorption


Book Description

Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.




Biosorbents for Metal Ions


Book Description

Metals can be dispersed, both naturally and by man's activities, into any of the Earth's elements - soil, water or air. Biological techniques for removing metal pollutants from soil, air or water are now attracting great interest, both because they are seen as more environmentally friendly than chemical treatments, and because, in some cases at lea




Heavy Metals in the Environment: Origin, Interaction and Remediation


Book Description

Excessive levels of heavy metals can be introduced into the environment, for example, by industrial waste or fertilizers. Soil represents a major sink for heavy metals ions, which can then enter the food chain via plants or leaching into groundwater. In Heavy Metal Ions in the Environment, the author looks at where heavy metals ions come from, how they interact with the environment and how they can be removed from the environment – by a process known as remediation. This book serves as a valuable addition to an increasingly important field of study, which is, at present, served by a limited number of archival texts. - Includes comprehensive coverage of heavy metal ions in the environment - Is practical and easy to read - Is suitable for students and researchers in environmental science and environmental or chemical engineering
