What is Riverbank Filtration? The purpose ofthis book is to show that riverbank filtration (RBF) isa low-cost and efficient alternative water treatment for drinking-water applications. There are two immediate benefits to the increased use of RBF: Minimized need for adding chemicals like disinfectants and coagulants to surface water to control pathogens. Decreased costs to the community without increased risk to human health. Butwhat,exactly, isRBF? In humid regions, river water naturally percolates through the ground into aquifers (which are layers of sand and gravel that contain water underground) during high-flow conditions. In arid regions, most rivers lose flow, and the percolating water passes through soil and aquifer material until it reaches the water table. During these percolation processes, potential contaminants present in river water are filtered and attenuated. If there are no other contaminants present in the aquifer or ifthe respective contaminants are present at lower concentrations, the quality of water in the aquifer can be ofhigher quality than that found in theriver. In RBF, production wells — which are placed near the banks ofrivers —pump large quantities ofwater.
Book Synopsis Riverbank Filtration for Water Security in Desert Countries by : Chittaranjan Ray
Download or read book Riverbank Filtration for Water Security in Desert Countries written by Chittaranjan Ray and published by Springer. This book was released on 2010-12-14 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverbank filtration is a low cost, yet efficient water treatment technology. It has most potential to provide safe drinking water to large cities located along rivers or lakes. In particular, it is ideal for large population centres in developing countries, where the cost of building extensive treatment facilities is prohibitive. Water filtration can be successfully implemented using naturally occurring sand and gravel along the river/lake banks. The cost of water produced by this means is much lower than that of water treated in conventional treatment plants. Authored by a multi-disciplinary team of experts, this volume addresses the scientific basis of the filtration process, and also numerous topics of importance for the planning, technical realization, and security of such plants. Their application for the removal of relevant chemical pollutants and a variety of pathogens is analysed in detail.

Download or read book Riverbank Filtration: Understanding Contaminant Biogeochemistry and Pathogen Removal written by C. Ray and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverbank filtration is widely used in Europe and to some extent in the United States for the public water supply. It is a cost-effective and realisable treatment technology in which horizontal and vertical wells pump a mixture of ground water and induced surface water from a river. This book describes the biogeochemical issues involved in contaminant removal from surface water and the mechanisms of pathogen removal. Specifically, the following three points are considered: *The role of hydrogeological and well construction factors in the development of redox zones at bank filtration sites and the resulting impacts on contaminant removal. *The mechanisms of pathogen removal, including the processes, colloid filtration, die-away, decay, and predation. *The status of riverbank filtration processes in NATO partner countries.

Available in PDF, EPUB and Kindle. Book excerpt: This report provides addresses the basic hydrology of RBF systems, focusing on the interaction of the river, the riverbed, the aquifer, and the well, along with the associated parameters that influence how much water will flow from a given system at a given site. The primary parameter evaluated was specific capacity (pump discharge per unit drawdown). Site and water quality characteristics thought to impact specific capacity were also evaluated, including stream velocity and slope, riverbed shear stress, riverbed media composition, aquifer and riverbed hydraulic conductivity, and river quality and temperature.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to investigate the clogging process in riverbank filtration (RBF) systems and identify factors significant to yield. Specific objectives included the following: Evaluate commonly available stream and aquifer characteristics from RBF systems with regards to system yield Collect data from the RBF system in Louisville and apply the information to clogging theory Provide recommendations regarding the design of future RBF systems with regards to riverbed clogging Data from the participating sites were compiled to allow easy comparison to future RBF sites. High-capacity RBF systems have been constructed in a wide range of hydrogeologic settings, and data from these sites provide insight to capacity-limiting factors in RBF systems. Field data for temperature, head, and riverbed flux rates into the riverbed were collected at Louisville, allowing estimates of riverbed hydraulic conductivity to be calculated as a function of distance from the well. These data indicated variations in riverbed hydraulic conductivity resulting from riverbed clogging and the development of unsaturated conditions. The impact of temperature on specific capacity was evaluated at four sites where adequate operating data were available. Wide variations in water viscosity associated with temperature resulted in the doubling of specific capacity from winter to summer, indicating that the rated capacity of RBF systems should be considered as a range between coldest and warmest water conditions. Information from this project was summarized into a set of recommendations for utilities considering the design of an RBF system for future water supply.
Book Synopsis Anthropogenic Aquifer Recharge by : Robert G. Maliva
Download or read book Anthropogenic Aquifer Recharge written by Robert G. Maliva and published by Springer. This book was released on 2019-05-07 with total page 861 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is an overview of the diversity of anthropogenic aquifer recharge (AAR) techniques that use aquifers to store and treat water. It focusses on the processes and the hydrogeological and geochemical factors that affect their performance. This book is written from an applied perspective with a focus of taking advantage of global historical experiences, both positive and negative, as a guide to future implementation. Most AAR techniques are now mature technologies in that they have been employed for some time, their scientific background is well understood, and their initial operational challenges and associated solutions have been identified. However, opportunities exist for improved implementation and some recently employed and potential future innovations are presented. AAR which includes managed aquifer recharge (MAR) is a very important area of water resources management and there is no recent books that specifically and comprehensively addresses the subject.
Book Synopsis Managed Aquifer Recharge for Water Resilience by : Peter Dillon
Download or read book Managed Aquifer Recharge for Water Resilience written by Peter Dillon and published by MDPI. This book was released on 2021-04-01 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a hard copy of the editorial and all the papers in a Special Issue of the peer-reviewed open access journal ‘Water’ on the theme ‘Managed Aquifer Recharge for Water Resilience’. Managed aquifer recharge (MAR) is the purposeful recharge of water to aquifers for subsequent recovery or environmental benefit. MAR is increasingly used to make water supplies resilient to drought, climate change and deteriorating water quality, and to protect ecosystems from declining groundwater levels. Global MAR has grown exponentially to 10 cu.km/year and will increase ten-fold within a few decades. Well informed hydrogeologists, engineers and water quality scientists are needed to ensure that this investment is effective in meeting increasingly pressing needs. This compilation contains lessons from many examples of existing projects, including several national and continental summaries. It also addresses the elements essential for identifying and advancing projects such as mapping aquifer suitability and opportunities, policy matters, operational issues, and some innovations in MAR methods and monitoring. This collection exemplifies the state of progress in the science and practice of MAR and is intended to be useful, at least to water managers, water utilities, agricultural water users and urban planners, to facilitate water resilience through new MAR projects.
Book Synopsis Factors Significant to Yield in Riverbank Filtration Systems by : Tiffany Gail Caldwell
Download or read book Factors Significant to Yield in Riverbank Filtration Systems written by Tiffany Gail Caldwell and published by . This book was released on 2005 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Use of riverbank filtration (RBF) recently has become more prevalent in the United States as more and more utilities seek to improve the quality of source waters used for water supply in response to the implementation of more stringent treatment regulations. Current methods of yield prediction for riverbank filtration systems fail to account fully for influences of site geometry, river hydraulics, and source water quality on long-term yield. As a result, systems often fail to produce in the long term at the rate predicted from pump tests and investigations. Yield in RBF systems is affected by a variety of factors related to the geology, hydraulics, site layout, and operational characteristics of each site. This paper identifies key parameters that affect yield in riverbank filtration systems and presents data for these parameters from RBF sites in the United States and in Europe. Data was collected from eleven riverbank filtration sites in the United States and Europe through Internet searches, literature searches, site visits, and email and phone correspondence. A simple analysis compared aquifer, river hydrology/hydraulics, site geometry, riverbed, and water quality data to operational data in an attempt to identify key factors that are significant to yield. The study was successful in demonstrating the important impact of temperature on specific capacity and identifying several other factors that showed some correlation with specific capacity. However, the impact of the majority of the factors was difficult to distinguish because of interdependencies, missing data, and the limited number of site investigated. The data included in the study provide a range of aquifer, river, riverbed, and water quality conditions in which riverbank filtration has been successfully implemented. The data generated provide means to facilitate the transfer of experience among interested parties.
Book Synopsis Recent Progress in Slow Sand and Alternative Biofiltration Processes by : Rolf Gimbel
Download or read book Recent Progress in Slow Sand and Alternative Biofiltration Processes written by Rolf Gimbel and published by IWA Publishing. This book was released on 2006-03-31 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slow sand filtration is typically cited as being the first "engineered" process in drinking-water treatment. Proven modifications to the conventional slow sand filtration process, the awareness of induced biological activity in riverbank filtration systems, and the growth of oxidant-induced biological removals in more rapid-rate filters (e.g. biological activated carbon) demonstrate the renaissance of biofiltration as a treatment process that remains viable for both small, rural communities and major cities. Biofiltration is expected to become even more common in the future as efforts intensify to decrease the presence of disease-causing microorganisms and disinfection by-products in drinking water, to minimize microbial regrowth potential in distribution systems, and where operator skill levels are emphasized. Recent Progress in Slow Sand and Alternative Biofiltration Processes provides a state-of-the-art assessment on a variety of biofiltration systems from studies conducted around the world. The authors collectively represent a perspective from 23 countries and include academics, biofiltration system users, designers, and manufacturers. It provides an up-to-date perspective on the physical, chemical, biological, and operational factors affecting the performance of slow sand filtration (SSF), riverbank filtration (RBF), soil-aquifer treatment (SAT), and biological activated carbon (BAC) processes. The main themes are: comparable overviews of biofiltration systems; slow sand filtration process behavior, treatment performance and process developments; and alternative biofiltration process behaviors, treatment performances, and process developments.

Book Synopsis Effectiveness of Bank Filtration for Water Supply in Arid Climates by : Ahmed Ragab Abdelrady Mahmoud
Download or read book Effectiveness of Bank Filtration for Water Supply in Arid Climates written by Ahmed Ragab Abdelrady Mahmoud and published by CRC Press. This book was released on 2021-02-25 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many developing countries, water demand is increasing while surface- and groundwater resources are threatened by pollution and overexploitation. Hence, a more sustainable approach to water resources management and water treatment is required. In this capacity, bank filtration is a natural treatment process that makes use of the storage and contaminant attenuation capacity of natural soil/rock. However, BF is site-specific and a significant knowledge gap exists regarding the design and management of bank filtration systems, particularly in developing countries. This research aimed to address these gaps and contribute to the transfer of bank filtration to developing countries. This study comprised both column and batch laboratory-scale experiments to determine the effect of environmental variables such as temperature, raw water organic composition and redox conditions on the removal of chemical pollutants such as organic matter, micro-pollutants and heavy metals as well as the mobility of iron, manganese and arsenic under anaerobic conditions. Ultimately, the effectiveness of BF for supplying high drinking water quality was assessed in a case study in Egypt. The study showed that more than 80% of biodegradable organic matter was removed during infiltration at temperatures between 20 and 30 °C. However, humic compounds enriched during BF, required post-treatment. Moreover, high humic content of infiltrating water reduced the removal of heavy metal and promoted the release of metal (loids) into the infiltrating water, rendering it more feasible to install BF wells within surface water systems with low levels of organic matter. Moderately-hydrophobic organic micropollutants were most persistent and required infiltration times longer than 30 days for complete elimination even at high temperatures (>20 °C). Finally, design parameters such as the number of infiltration wells should be configured to minimise the proportion of polluted groundwater in the pumped water. Overall, this study provides insight into the effectiveness of BF in removing chemical pollutants from surface water and proposes guidelines for the successful application of BF in developing countries where arid conditions and high temperatures prevail.
Book Synopsis Drinking Water Treatment by : Chittaranjan Ray
Download or read book Drinking Water Treatment written by Chittaranjan Ray and published by Springer Science & Business Media. This book was released on 2011-06-16 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to “democratize” membrane filtration have been presented. Riverbank filtration is a “natural” filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on threats, especially contaminants, to drinking water and the supply system, especially in municipalities but also in industrial and even residential settings. The safety, security, and suitability landscape can be described as dynamic and complex stemming from necessity and hence culpability due to the emerging threats and risks, vis-a-vis globalization resulting in new forms of contaminants being used due to new technologies. The book provides knowledge and guidance for engineers, scientists, designers, researchers, and students who are involved in water, sustainability, and study of security issues. This book starts out with basics of water usage, current statistics, and an overview ofwater resources. The book then introduces different scenarios of safety and security and areas that researchers need to focus. Following that, the book presents different types of contaminants – inadvertent, intentional, or incidental. The next section presents different methodologies of contamination sensing/detection and remediation strategies as per guidance and standards set globally. The book then concludes with selected chapters on water management, including critical infrastructure that is critical to maintaining safe water supplies to cities and municipalities. Each chapter includes descriptive information for professionals in their respective fields. The breadth of chapters offers insights into how science (physical, natural, and social) and technology can support new developments to manage the complexity resident within the evolving threat and risk landscape.
