Available in PDF, EPUB and Kindle. Book excerpt: Congress created the Arsenic Water Technology Partnership (AWTP) in 2002 to develop and provide solutions for the cost-effective removal of arsenic from drinking water. The AWTP was funded by four congressional appropriations (FY03-FY06) to evaluate and develop new technologies that could significantly reduce compliance costs associated with the new 0.010 mg/L maximum contaminant level (MCL) for arsenic in drinking water. Initially focused on arsenic research, in FY06 the AWTP was expanded to include desalination research upon recognition that the research challenges were similar. The funding for the research and subsequent transfer of technology was made available by Congress through the Department of Energy (DOE). The AWTP was a collaborative effort between DOE's Sandia National Laboratories (Sandia), Water Research Foundation (WaterRF, formerly Awwa Research Foundation) and WERC: A Consortium for Environmental Education and Technology Development based at New Mexico State University (WERC). Key features of the AWTP included technology development, technology implementation/testing and technology transfer. Each of the partners evaluated and oversaw development of new arsenic and desalination treatment technologies, and the technology transfer program ensured that successful technologies were transferred to the water supply community. Through the use of an arsenic treatment cost model, training sessions and a web site, information on arsenic removal and desalination technologies was transferred to stakeholders. KEY ACCOMPLISHMENTS The AWTP partnership funded research on, and deployment and testing of, innovative arsenic and desalination removal technologies; education for small and large water system operators; and development of a comprehensive web-based tool for arsenic treatment technology selection using site-specific data. As water becomes scarcer, and potable water supplies become increasingly vulnerable to contamination, the development of affordable water treatment systems is critical. Choosing the best available treatment system can be difficult. The AWTP has developed and evaluated improved arsenic and desalination treatment systems and provided that information to water utilities and stakeholders. Key technology advancements achieved by the partnership include: ARSENIC Development and full-scale implementation (San Antonio, NM) of an in-situ treatment process that is producing drinking water without the generation of any residuals that require disposal. The way is now paved for in-situ treatment to be used throughout the U.S. Detailed information on how to evaluate and prevent unintended consequences of bringing an arsenic treatment technology online prior to implementation, including: -potential for increased distribution system corrosion -potential for treatment systems to release arsenic into drinking water due to unintended pH variation Methods and options on the most appropriate ways to classify, stabilize and dispose of potentially hazardous arsenic-containing water treatment residuals A much improved understanding of water quality characteristics that impact specific treatment technologies allowing for site-specific selection of a best-available-technology Demonstrated at pilot scale that use of ultra-light filter media in a coagulation-filtration process can significantly reduce required backwash water volume and achieve 99 percent feedwater recovery while effectively removing arsenic Development of a polymeric ligand exchanger that selectively and effectively removes the oxidized form of arsenic under typical groundwater conditions, which is best utilized for treating water with high sulfate and relatively low alkalinity Development of iron-granular activated carbon (GAC) and titanium-GAC composite adsorbents for arsenic removal, which can simultaneously remove contaminants that adsorb onto activated carbon, e.g., neutral organic chemicals, radionuclides, and taste-and-odor compounds DESALINATION Development of a comprehensive and detailed set of guidelines for utilities wanting to evaluate and bring a desalination treatment process online Improved understanding of membrane fouling in seawater desalination, and evaluation of a pretreatment method to minimize fouling Improved understanding of mechanisms underlying VSEP, a membrane-based inland brackish desalination process that may enhance recovery by up to 25% Demonstrated a hybrid reverse osmosis-forward osmosis process which can enhance seawater desalination through dilution with treated wastewater.
Book Synopsis Evaluation of Innovative Arsenic Treatment Technologies by : Malcolm Dean Siegel
Download or read book Evaluation of Innovative Arsenic Treatment Technologies written by Malcolm Dean Siegel and published by . This book was released on 2006 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lowering of the drinking water standard (MCL) for arsenic from 50 {micro}g/L to 10 {micro}g/L in January 2006 could lead to significant increases in the cost of water for many rural systems throughout the United States. The Arsenic Water Technology Partnership (AWTP), a collaborative effort of Sandia National Laboratories, the Awwa Research Foundation (AwwaRF) and WERC: A Consortium for Environmental Education and Technology Development, was formed to address this problem by developing and testing novel treatment technologies that could potentially reduce the costs of arsenic treatment. As a member of the AWTP, Sandia National Laboratories evaluated cutting-edge commercial products in three annual Arsenic Treatment Technology Vendors Forums held during the annual New Mexico Environmental Health Conferences (NMEHC) in 2003, 2004 and 2005. The Forums were comprised of two parts. At the first session, open to all conference attendees, commercial developers of innovative treatment technologies gave 15-minute talks that described project histories demonstrating the effectiveness of their products. During the second part, these same technologies were evaluated and ranked in closed sessions by independent technical experts for possible use in pilot-scale field demonstrations being conducted by Sandia National Laboratories. The results of the evaluations including numerical rankings of the products, links to company websites and copies of presentations made by the representatives of the companies are posted on the project website at http://www.sandia.gov/water/arsenic.htm. This report summarizes the contents of the website by providing brief descriptions of the technologies represented at the Forums and the results of the evaluations.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause

Download or read book Diverting the Flow written by Margreet Zwarteveen and published by Zubaan. This book was released on 2014-03-11 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the South Asian region, water determines livelihoods and in some cases even survival. However, water also creates exclusions. Access to water, and its social organisation, are intimately tied up with power relations. This book provides an overview of gender, equity and water issues relevant to South Asia. The essays empirically illustrate and theoretically argue how gender intersects with other axes of social difference such as class, caste, ethnicity, age and religion to shape water access, use and management practices. Divided into six thematic sections, each of which starts with an introduction of relevant concepts, debates and theories, the book looks at laws and rights; policies; technologies and intervention strategies. In all, the book clearly shows how understanding and changing the use, distribution and management of water is conditional upon understanding and accommodating gender relations. Published by Zubaan.
