This book was released on 2008-09-14 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: La escasez de agua dulce amenaza el bienestar de la humanidad y, en última instancia, su supervivencia. La desalinización de agua de mar se plantea como una solución muy prometedora, pero hay que tener en cuenta el coste energético de estas tecnologías y los impactos ambientales que pueden provocar, así como los diferentes usos a los que se puede destinar el agua desalinizada. El principal objetivo de este trabajo es poner en entredicho la sostenibilidad a largo plazo de la tecnología desalinizadora como solución para afrontar la crisis mundial del agua dulce. Se discute además acerca del concepto de escasez, utilizando la perspectiva Norte-Sur. No parece que el suministro de agua para el turismo tenga mucho que ver con la escasez de agua de los pobres: ¿para qué se usa el agua?; ¿para satisfacer un lujo o para mantener el medio de vida? Para abordar estas cuestiones es necesario un enfoque basado en un escenario de «necesidades básicas». Se han escogido los casos prácticos de la ciudad de El Aaiún (Sáhara marroquí), la isla canaria de Lanzarote (España), la franja de Gaza (Territorios Ocupados Palestinos) y los barrios marginales de Chennai (sur de la India) para ilustrar cómo la tecnología desalinizadora se utiliza para mitigar situaciones de escasez con un elemento dominante distinto en cada caso: físico, socialmente construido, políticamente construido o estructural. Más allá del cambio tecnológico, este estudio se centra en la equidad tecnológica como una piedra angular del debate.

Book Synopsis Membrane Based Desalination by : Enrico Drioli
Download or read book Membrane Based Desalination written by Enrico Drioli and published by IWA Publishing. This book was released on 2011-04-14 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reverse osmosis is the dominant technology in water desalination. However, some critical issues remain open: improvement of water quality, enhancement of the recovery factor, reduction of the unit water cost, minimizing the brine disposal impact. This book aims to solve these problems with an innovative approach based on the integration of different membrane operations in pre-treatment and post-treatment stages. Membrane-Based Desalination: An Integrated Approach (acronym MEDINA) has been a three year project funded by the European Commission within the 6th Framework Program. The project team has developed a work programme aiming to improve the current design and operation practices of membrane systems used for water desalination, trying to solve or, at least, to decrease the critical issues of sea and brackish water desalination systems. In the book, the main results achieved in the nine Work Packages constituting the project will be described, and dismissed by the leaders of the various WPs. The following areas are explored in the book: the development of advanced analytical methods for feed water characterization, appropriate fouling indicators and prediction tools, procedures and protocols at full-scale desalination facilities; the identification of optimal seawater pre-treatment strategies by designing advanced hybrid membrane processes (submerged hollow fibre filtration/reaction, adsorption/ion exchange/ozonation) and comparison with conventional methods; the optimisation of RO membrane module configuration, cleaning strategies, reduction of scaling potential by NF; the development of strategies aiming to approach the concept of Zero Liquid Discharge (increasing the water recovery factor up to 95% by using Membrane Distillation - MD; bringing concentrates to solids by Membrane Crystallization or Wind Intensified Enhanced Evaporation) and to reduce the brine disposal environmental impact and cost; increase the sustainability of desalination process by reducing energy consumption (evaluation of MD, demonstration of a new energy recovery device for SWRO installations) and use of renewable energy (wind and solar).

Book Synopsis Efficient Desalination by Reverse Osmosis by : Stewart Burn
Download or read book Efficient Desalination by Reverse Osmosis written by Stewart Burn and published by IWA Publishing. This book was released on 2015-09-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early applications of desalination were small-scale plants deploying a range of technologies. However with the technological developments in Reverse Osmosis, most new plants use this technology because it has a proven history of use and low energy and capital costs compared with other available desalination technologies. This has led to the recent trend for larger seawater desalination plants in an effort to further reduce costs, and 1000 MLD seawater desalination plants are projected by 2020. Efficient Desalination by Reverse Osmosis recognises that desalination by reverse osmosis has progressed significantly over the last decades and provides an up to date review of the state of the art for the reverse osmosis process. It covers issues that arise from desalination operations, environmental issues and ideas for research that will bring further improvements in this technology. Efficient Desalination by Reverse Osmosis provides a complete guide to best practice from pre-treatment through to project delivery. Editors: Stewart Burn, Visiting Scientist, CSIRO Manufacturing.

Book Synopsis Seawater Reverse Osmosis Desalination by : Sergio G. Salinas-Rodriguez
Download or read book Seawater Reverse Osmosis Desalination written by Sergio G. Salinas-Rodriguez and published by IWA Publishing. This book was released on 2021-05-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desalination as a method to provide clean drinking water has become vital – particularly in a context where drought, water scarcity and rapid quality decrease of water bodies have become an undeniable reality. After more than half a century of membrane-based desalination, fouling and scaling is still a dominant challenge. In membrane technologies, in particular, fouling and scaling are a major issue with respect to design, operation, reliability of the technologies and cost. This textbook covers theory and practice and is intended for designers, operators, consultants, suppliers and students. Principles of ultra- and nanofiltration and reverse osmosis (RO) are discussed, enabling the reader to understand the link between design, operation and fouling and scaling. Fouling (particulate, organic -including algal bloom events, inorganic, and biofouling) and scaling are treated in detail, including parameters to determine fouling and scaling potential of feed waters. Principles of conventional and advanced pre-treatment processes are highlighted and their effect on preventing fouling and scaling. In addition, the process design of RO systems and the recent advances in seawater RO and emerging membrane-based processes for seawater desalination are presented.

Download or read book Desalination written by Michael Schorr and published by BoD – Books on Demand. This book was released on 2011-02-28 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book comprises 14 chapters covering all the issues related to water desalination. These chapters emphasize the relationship between problems encountered with the use of feed water, the processes developed to address them, the operation of the required plants and solutions actually implemented. This compendium will assist designers, engineers and investigators to select the process and plant configuration that are most appropriate for the particular feed water to be used, for the geographic region considered, as well as for the characteristics required of the treated water produced. This survey offers a comprehensive, hierarchical and logical assessment of the entire desalination industry. It starts with the worldwide scarcity of water and energy, continues with the thermal - and membrane-based processes and, finally, presents the design and operation of large and small desalination plants. As such, it covers all the scientific, technological and economical aspects of this critical industry, not disregarding its environmental and social points of view. One of InTech's books has received widespread praise across a number of key publications. Desalination, Trends and Technologies (Ed. Schorr, M. 2011) has been reviewed in Corrosion Engineering, Science

Download or read book Desalination: written by Committee on Advancing Desalination Technology and published by National Academies Press. This book was released on 2008-08-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater. Desalination assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities.
