Download or read book Biosorption for Wastewater Contaminants written by Rangabhashiyam Selvasembian and published by John Wiley & Sons. This book was released on 2021-10-25 with total page 324 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.
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.

Download or read book Application of Adsorbents for Water Pollution Control written by Amit Bhatnagar and published by Bentham Science Publishers. This book was released on 2012-11-11 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among various water and wastewater treatment technologies, the adsorption process is considered better because of lower cost, simple design and easy operation. Activated carbon (a universal adsorbent) is generally used for the removal of diverse types of pollutants from water and wastewater. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. However, widespread use of commercial activated carbon is sometimes restricted especially in developing or poor countries due to its higher costs. Attempts are therefore being made to develop inexpensive adsorbents utilizing abundant natural materials, agricultural and industrial waste materials. Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. This e-book explores knowledge on recent developments in adsorbents synthesis and their use in water pollution control. This handy reference work is intended for researchers and scientists actively engaged in the study of adsorption and the development and application of efficient adsorption technology for water treatment. This e-book covers a wide range of topics including modeling aspects of adsorption process and the applications of conventional and non-conventional adsorbents in water remediation emphasizing sorption mechanisms of different pollutants on the adsorbents.
Download or read book Sustainable Green Chemical Processes and their Allied Applications written by Inamuddin and published by Springer Nature. This book was released on 2020-05-30 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization, industrialization, and unethical agricultural practices have considerably negative effects on the environment, flora, fauna, and the health and safety of humanity. Over the last decade, green chemistry research has focused on discovering and utilizing safer, more environmentally friendly processes to synthesize products like organic compounds, inorganic compounds, medicines, proteins, enzymes, and food supplements. These green processes exist in other interdisciplinary fields of science and technology, like chemistry, physics, biology, and biotechnology, Still the majority of processes in these fields use and generate toxic raw materials, resulting in techniques and byproducts which damage the environment. Green chemistry principles, alternatively, consider preventing waste generation altogether, the atom economy, using less toxic raw materials and solvents, and opting for reducing environmentally damaging byproducts through energy efficiency. Green chemistry is, therefore, the most important field relating to the sustainable development of resources without harmfully impacting the environment. This book provides in-depth research on the use of green chemistry principles for a number of applications.

Download or read book Industrial Wastewater Reuse written by Maulin P. Shah and published by Springer Nature. This book was released on 2023-07-21 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book identifies emerging technologies that allow the reuse and regeneration of industrial wastewater with innovative and applied approaches throughout the wastewater treatment cycle. Today, it is increasingly clear that treated urban wastewater, whose reuse has become an important component of long-term water management worldwide, is a key source of chemical pollutants and emerging biological concerns. Current water-quality guidelines for reclaimed wastewater predominantly address the risks associated with the presence of microbial organisms and chemical parameters such as biological oxygen demand, chemical oxygen demand, E. coli and worms, and in some cases heavy metals; however, they are insufficient for the full evaluation of risks. The global growth of population is concentrated in urban areas; therefore, most of the challenges and solutions related to wastewater reside in urban treatment plants. Unless wastewater management and wastewater governance processes are significantly improved within a decade, it is likely that our societies will face severe and prolonged water insecurity and urban floods. The application of sustainable technologies can eliminate or minimize micro-contaminants in wastewater. Several organizations focus on the potential impacts to humans and their environments by wastewater reuse. This book gathers new research and reviews work from researchers and scientists to identify the main barriers and limitations that will need to be overcome, so that wastewater reuse strategies gain more momentum and will be adopted more efficiently worldwide. The book is designed for engineers, scientists, and other professionals who are seeking an excellent introduction to and basic knowledge of the principles of environmental bioremediation technologies.
