This book was released on 2012-07 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Removal of heavy metal ions from water and wastewater has became more important due rapid industrialization. However among all the conventional methods application of adsorption for heavy metal removal gained more importance. However application of activated carbon as adsorbent became more popular, however due to cost effectiveness its application been limited. Low-cost adsorbents from agricultural bio waste were observed as novel materials for metal removal. This book includes application of agro-biomass as adsorbent for metal removal. The book consists of brief introduction of water pollution and methods for removal of metal ions and adsorption mechanism. Also several empirical models have been adopted to analyze the equilibrium data. Kinetics and isotherm have been studied. This book is very useful for scientists, engineers and researcher who are working in the areas of adsorption and biosorption.
Download or read book Biosorption written by Jan Derco and published by BoD – Books on Demand. This book was released on 2018-07-18 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Physicochemical Treatment Processes by : Lawrence K. Wang
Download or read book Physicochemical Treatment Processes written by Lawrence K. Wang and published by Springer Science & Business Media. This book was released on 2005-03-11 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste exists, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of the Handbook of Environmental Engineering series is to help readers formulate answers to the last two questions. The traditional approach of applying tried-and-true solutions to specific pollution pr- lems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a “methodology of pollution c- trol. ” However, realization of the ever-increasing complexity and interrelated nature of current environmental problems makes it imperative that intelligent planning of pollution abatement systems be undertaken.

Book Synopsis Biosorption for Wastewater Contaminants by : Pardeep Singh
Download or read book Biosorption for Wastewater Contaminants written by Pardeep Singh and published by John Wiley & Sons. This book was released on 2021-10-13 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a variety of environments, both urban and rural. This book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.
Book Synopsis Use of Sludge from Wastewater Treatment Plants as Adsorbents for Removal of Heavy Metal Ions from Water by :
Download or read book Use of Sludge from Wastewater Treatment Plants as Adsorbents for Removal of Heavy Metal Ions from Water written by and published by . This book was released on 2007 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sludge from municipal and industrial wastewater treatment plants were used as adsorbents for removal of heavy metal ions from water. Both of sewage sludge were obtained from activated sludge bilolgical treatment processes. The adsorption studies were performed using batch method and the adsorption efficiency of both sludge for Cd(II), Ni(II) and Pb(II) ions were compared under influence of certain parameters. The residual metal concentrations were determined by FASS. The result from surface characterization and elemental analysis indicated that both sludge had low surface area and consisted of carbonaceous substances. The results from adsorption studies showed that suitable contact time for removal of Cd(II), Ni(II) and Pb(II) ions were 1 hour and the suitable pH values werre 7 for Cd(II) and Ni(II), and 5 for Pb(II), respectively. The adsorption of the metal ions on both sewage sludge fit well Langmuir model and the adsorption kinetics followed the pseudo-second-order kinetics. It was observed that an increase in adsorbent resuluted in an increase in removal effciencies and a faster adsorption rate. The maximum adsorption capacities of Cd(II), Ni(II) and Pb(II) ions were 0.140, 0.053 and 0.171 mmol g-1 by municipal sludge, and 0.147, 0.064 and 0.150 mmol g-1 by industrial sludge, respectively. The adsorbents were applied to remove the metal ions in real wastewater containing 8.3 mg L-1 of Cd(II), 5.1 mg L-1 of Ni(II) and 27.4 mg L-1 of Pb(II) ions and the total removal of the metal ions was obtained when using 2 g mg L-1 of sludge. The result from sequential extraction indicated that metal distributed in different fractions of the sewage sludge, and mostly in the residual fraction. The results from the standard leaching ttest showed that the concentrations of metal in the leachate were greater than the total threshold limit concentration (TTLC) for all metals. Therefore, the used sludge was classified as hazardous waste. All of the results showed that the adsorbents derived from municipal and industrial sludge have a good potential to be used as adsorbents for removal of Cd(II), Ni(II) and Pb(II) ions in water. However, the used adsorbents had to dispose correctly.
