Available in PDF, EPUB and Kindle. Book excerpt: Riverbank filtration (RBF) schemes for the production of drinking water are increasingly challenged by new constituents of concern, such as organic micropollutants and pathogens in the source water and hydrological flow variations due to weather extremes. RBF and new technology components are integrated and monitoring and operating regimes are adopted to further optimize water treatment in bank filtration schemes for these new requirements. This Special Issue presents results from the EU project AquaNES "Demonstrating synergies in combined natural and engineered processes for water treatment systems" (www.aquanes.eu). Additionally, papers from other research groups cover the efficiency of bank filtration and post-treatment, advantages and limitations of combining natural and engineered processes, parameter-specific assessment of removal rates during bank filtration, and the design and operation of RBF wells. The feasibility, design, and operation of RBF schemes under specific site conditions are highlighted for sites in the US, India, and South Korea.
Book Synopsis Effectiveness of Bank Filtration for Water Supply in Arid Climates by : Ahmed Ragab Abdelrady Mahmoud

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 Multiple Objective Treatment Aspects of Bank Filtration by : Sung Kyu Maeng
Download or read book Multiple Objective Treatment Aspects of Bank Filtration written by Sung Kyu Maeng and published by CRC Press. This book was released on 2023-05-09 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bank filtration (BF) is a natural water treatment process which induces surface water to flow in response to a hydraulic gradient through soil/sediment and into a vertical or horizontal well. It is a relatively cost-effective, robust and sustainable technology. From a historical perspective, BF is first mentioned in the bible, and the process has been recognized as a proven method for drinking water treatment in Europe for more than 100 years. However, the mechanisms of removal of different contaminants during BF are not fully understood. This study showed that BF is an effective multiple objective barrier for removal of different contaminants present in surface water sources including bulk organic matter and organic micropollutants (OMPs) like pharmaceutically active compounds and endocrine disrupting compounds. It was found that biodegradation and adsorption play primary and secondary roles, respectively, in the removal of OMPs during soil passage. Furthermore, using field data from BF sites and chemical properties of OMPs, models were developed to estimate the removal of OMPs during soil passage. It can be concluded that the removal efficiencies of BF for these contaminants can be maximised by proper design and operation of recovery wells taking into consideration source water quality characteristics and local hydrogeological conditions.

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.

Linsky National Water Research Institute Fountain Valley, California, United States Gina Melin National Water Research Institute Fountain Valley, California, United States 1. 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 Groundwater by : Raya Marina Stephan
Download or read book Groundwater written by Raya Marina Stephan and published by Taylor & Francis. This book was released on 2023-02-21 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is invisible, but its impact is visible everywhere. Everything around us relies on groundwater, our drinking water and sanitation, our food supply and our natural environment. Yet because it is invisible, information, management and governance of groundwater is often poor and inadequate. This book contributes to UN Water Groundwater year (2022), and to the effort of “making the invisible, visible”. Through worldwide case studies ranging from the Americas (California, Brazil), to Asia (India, Iran, Lao PDR, Nepal), Africa (Malawi, Tanzania, South Africa) and the MENA region (Lebanon, Morocco, Yemen), including cases of transboundary aquifers, the chapters in this edited volume reflect important recent advances in interdisciplinary knowledge on the governance, management, practice and science-policy interfaces of groundwater. An insightful resource for researchers and planners in the field of environmental policies, water laws, climate change and groundwater governance, this book comes with a new Introduction. The other chapters were originally published in Water International.
Download or read book TECHNEAU written by Christian Kazner and published by IWA Publishing. This book was released on 2009-06-14 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The best papers from the three-day conference on Safe Drinking Water from Source to Tap June 2009 in Maastricht are published in this book covering the themes of challenges of the water sector and adaptive strategies, treatment, distribution, risk assessment and risk management, sensors and monitoring, small scale systems, simulation, alternative water supply & sources, consumer involvement, and future drinking water. Worldwide, the water supply sector is facing tremendous challenges. Every new emerging contaminants and pathogens and aging infrastructures that are vulnerable for deliberate contamination pose a threat to the quality of water supplies. Shortage of good quality and readily treatable resources is increasing due to global warming, urbanisation and pollution from agriculture and industry. Regulators and consumers are becoming more demanding. Techneau - the largest European project on drinking water - addresses these challenges by developing adaptive supply system options and new and improved treatment and monitoring technologies. Future system options to be studied are flexible, small scale and multi-source supplies, utilising non conventional resources like brackish ground water, treated wastewater and urban groundwater.
