Drinking Water Distribution Systems
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309133955
Category : Science
Languages : en
Pages : 404
Book Description
Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Desalination
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309119235
Category : Science
Languages : en
Pages : 313
Book Description
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.

Small-scale water supply system (SSS) for remote and rural areas in developing countries
Author: Jose Abdon Ordóñez Andrade
Publisher: kassel university press GmbH
ISBN: 3737605505
Category :
Languages : en
Pages : 333
Book Description
The Waterbackpack PAUL -Portable Aqua Unit for Life Saving- is a water treatment unit based on the Ultra-Low Pressure Ultrafiltration (ULP-UF) technology and is since 2010 successfully applied as a fast response to get safe water during natural disasters or emergencies in more than 2 000 cases worldwide. In addition, PAUL has demonstrated that the ULP-UF technology can be used in permanent decentralised drinking-water supply for remote and rural areas, as it is easy to handle and does require neither chemicals nor energy consumption nor spare parts on a regular basis. Hence, the ULP-UF is an appropriate solution in the process of reaching the Sustainable Development Goals (SDGs), ensure by 2030 access to safe drinking water worldwide. However, during long-term uses and under certain water characteristics, the ULP-UF faces some operational and maintenance challenges. The biofouling adhered to the membrane surface may lead to severe flux reduction. In addition, some re-growth of bacteria may take place on the permeate side because of the presence of high content of natural organic matter (NOM) in the raw water, especially Biopolymer and Humic Acids. Therefore, the aim of this study was to integrate some appropriate treatment steps before the ULP-UF technology, so that a reduction of attachment of NOM and biofilm to the membrane could be achieved and thus an increase of permeate flux and a reduction of potential regrowth of bacteria on permeate water could be accomplished.
