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 Selective Removal of Arsenic from Desalination Concentrate Using Drinking Water Treatment Solids by : Xuesong Xu
Download or read book Selective Removal of Arsenic from Desalination Concentrate Using Drinking Water Treatment Solids written by Xuesong Xu and published by . This book was released on 2015 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desalination of impaired water such as brackish water, seawater, and wastewater has been used to diversify fresh water sources. Membrane-based processes, which separate feed water into product water and concentrate, have been widely installed. However, concentrate management has been one of the most challenging issues with desalination, especially for inland areas where concentrate disposal options are limited. This study focused on selective removal of arsenate from reverse osmosis (RO) concentrate. The objectives of this study are aimed to investigate the feasibility of using drinking water treatment solids (DWTS) to remove arsenate in RO concentrate, and develop a "waste-treat-waste" approach to facilitate concentrate disposal and beneficial use. DWTS is a residual produced during the process of water treatment by using ferric-based or alumina-based coagulants. Although previous studies have explored arsenic removal by DWTS, there is lack of systematic study investigating removal efficiency of arsenic from saline water, such as desalination concentrate, in which competition with co-existing ions and high ionic strength may affect the selective sorption of arsenic. Therefore, this study focused on investigating the sorption of arsenate from RO concentrate using DWTS during continuous-flow testing. The impacts of operating conditions on arsenate removal were investigated including pH, initial arsenate concentration, hydraulic retention time, temperature, loading rate, and different types of DWTS. The results indicated that DWTS was a promising low-cost sorbent for arsenate removal from desalination concentrate.

This book was released on 2009-11-24 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is essential for life, a strategic resource for every country and population. Its availability and sanitary safety is highly connected with the health and economy status of population. Burden of disease due to polluted water is a major public health problem throughout the world. Many pollutants in water streams have been identified as toxic and harmful to the environment and human health, and among them arsenic, mercury and cadmium are considered as high priority ones. Providing population with safe drinking water became the priority and at the same time a big challenge for the modern society. Many funding agencies in various countries have assigned a high priority to the envir- mental security and pollution prevention. UN, being one of them, launched the “International Decade for Action: Water for life 2005–2015. ” Therefore, today’s political and social climate presents an important opportunity to implement principles of sustainable development and to preserve resources essential for future life. This process requires interdisciplinary approach; it is critically important to stimulate interactions between medical doctors, chemists, physicist, materials scientists, engineers and policy makers, which are already experienced in their specific areas. It is also our ethical obligation to preserve existing water resources and existing eco systems enhancing their biodiversity. The NATO Advanced Research Workshop “Water Treatment Te- nologies for the Removal of High-Toxicity Pollutants” took place on September 13–17, 2008 in Košice, Slovak Republic.
