Book Synopsis Arsenic Removal from Contaminated Groundwater by : Sirshendu De
Download or read book Arsenic Removal from Contaminated Groundwater written by Sirshendu De and published by The Energy and Resources Institute (TERI). This book was released on 2012-01-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of groundwater with arsenic is being considered a pervasive and critical issue in recent years. Large areas in India, Bangladesh, South East Asia, and other parts of the world are suffering from this problem. Arsenic Removal from Contaminated Groundwater presents a comprehensive discussion on various important issues, including state-of-the-art arsenic removal technologies, preparation and performance analysis of laterite, and scale-up issues and design of a household filter. It also expounds the potentiality of raw laterite and treated laterite as low-cost arsenic adsorbents. The efficiency of adsorbent capacity is evaluated using real arsenic contaminated groundwater collected from an affected area in West Bengal, India. The topic is an emerging area and most of the work presented has the potential of field application.

Book Synopsis In Situ Groundwater Arsenic Removal Using Iron Oxide-coated Sand by : Hongxu Yu
Download or read book In Situ Groundwater Arsenic Removal Using Iron Oxide-coated Sand written by Hongxu Yu and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many regions of the world, groundwater is contaminated with a high level of arsenic that must be treated before it can be safely used as drinking water. In situ immobilization of arsenic from groundwater within subsurface environment could have major advantages over the conventional above-ground chemical coagulation-precipitation treatment process. In this study, we develop a novel technique that can in situ emplace iron oxides onto the sand grain surface of porous media under mild chemical and temperature conditions. The technique involves sequential injections of a preconditioned ferrous iron solution and an oxidant solution and then orchestrate the advective-diffusive transport of the two reagents in porous media to create an overlapped reaction zone where ferrous iron is oxidized and precipitated on the sand grain surfaces. We demonstrate through bench-scale column tests the feasibility of using this technique to create a large-scale iron oxide-enriched reactive barrier in subsurface environment for in situ removal of arsenic. A sand filter with a fresh iron oxide coating can treat thousands of pore volumes of water contaminated with dozens of ppb arsenic before the coating needs to be regenerated. Arsenic breakthrough curves through the sand filter suggest that both reversible adsorption and irreversible precipitation are responsible for removing arsenic from the water. Unlike conventional excavate-and-fill permeable reactive barriers, the treatment capacity of our in situ created barrier can be in situ regenerated and replenished with a fresh coating.
Book Synopsis In Situ Iron Oxide Emplacement for Groundwater Arsenic Remediation by : Thomas Sunday Abia

Available in PDF, EPUB and Kindle. Book excerpt: Iron oxide-bearing minerals have long been recognized as an effective reactive media for arsenic-contaminated groundwater remediation. This research aimed to develop a technique that could facilitate in situ oxidative precipitation of Fe3+ in a soil (sand) media for generating a subsurface iron oxide-based reactive barrier that could immobilize arsenic (As) and other dissolved metals in groundwater. A simple in situ arsenic treatment process was successfully developed for treating contaminated rural groundwater using iron oxide-coated sand (IOCS). Using imbibition flow, the system facilitated the dispersive transport of ferrous iron (Fe2+) and oxidant solutions in porous sand to generate an overlaying blanket where the Fe2+ was oxidized and precipitated onto the surface as ferric oxide. The iron oxide (FeOx) emplacement process was significantly affected by (1) the initial surface area and surface-bound iron content of the sand, (2) the pH and solubility of the coating reagents, (3) the stability of the oxidant solution, and (4) the chemical injection schedule. In contrast to conventional excavate-and-fill treatment technologies, this technique could be used to in situ replace a fresh iron oxide blanket on the sand and rejuvenate its treatment capacity for additional arsenic removal. Several bench-scale experiments revealed that the resultant IOCS could treat arsenic-laden groundwater for extended periods of time before approaching its effective life cycle. The adsorption capacity for As(III) and As(V) was influenced by (1) the amount of iron oxide accumulated on the sand surface, (2) the system pH, and (3) competition for adsorption sites from other groundwater constituents such as silicon (Si) and total dissolved solids (TDS). Although the IOCS could be replenished several times before exhaustion, the life cycle of the FeOx reactive barrier may be limited by the gradual loss of hydraulic conductivity induced by the imminent reduction of pore space over time.

Book Synopsis The Elements of Environmental Pollution by : John Rieuwerts
Download or read book The Elements of Environmental Pollution written by John Rieuwerts and published by Routledge. This book was released on 2017-07-14 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental pollution is one of humanity’s most pressing issues and will remain so for the foreseeable future. Anthropogenic activity is disturbing natural cycles and generating pollutants that are altering the atmosphere, accumulating in the food chain and contaminating the world’s soils, rivers and oceans. Human health and ecosystems continue to be damaged by toxic metals, persistent organic pollutants, radionuclides and other hazardous materials. The Elements of Environmental Pollution provides comprehensive coverage of this essential subject. It explains the key principles of pollution science, assesses human disturbances of natural element cycles and describes local and global pollution impacts, from smoggy cities, polluted lakes and toxic soils to climate change, ocean acidification and marine dead zones. The book is informed by the latest pollution research and benefits from numerous real-world examples and international case studies. A comprehensive glossary provides clear and concise explanations of key concepts. This textbook will support teaching and learning in environment-related university courses and will be vital reading for anyone with an interest in environmental protection.

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.
