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.

Book Synopsis Arsenic Water Technology Partnership Final Technical Report by :
Download or read book Arsenic Water Technology Partnership Final Technical Report written by and published by . This book was released on 2010 with total page 371 pages. 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 Toward Sustainable Water Treatment by : Lauren Nicole Pincus
Download or read book Toward Sustainable Water Treatment written by Lauren Nicole Pincus and published by . This book was released on 2021 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Access to clean drinking water is a basic human right, yet hundreds of millions of people around the planet are unfortunately forced to drink contaminated waters. Arsenic contaminated drinking water is responsible for the largest global mass poisoning in history in India and Bangladesh where approximately 85 million people have been exposed to either drinking water or crops contaminated with arsenic. Within the United States, high costs of treatment in small to very small communities pose significant barriers to removal of contaminants such as arsenic beneath regulatory limits. This dissertation will detail the development of adsorbent technologies capable of removing arsenic more efficiently and cost effectively with the aim of increasing ease use of these treatment systems in the areas they are still needed most- more rural communities. This goal will be accomplished through two main approaches: 1. Multifunctionality (technologies capable of performing traditionally separate steps in the treatment process simultaneously) and 2. Selectivity (targeted removal of arsenic in the presence of its adsorptive competitors). This work will begin by comprehensively and critically reviewing the literature related to competitive and selective adsorption of oxyanions. Strength of target/competitive oxyanion pairs, metrics to quantify selectivity, and mechanisms by which selectivity can be developed will be detailed. Next, a Cu(II)-n-TiO2-chitosan (CuTICB) adsorbent will be designed which is capable of both multifunctionality (simultaneous photooxidation of As(III) to As(V) in UV light) and selective adsorption of As(V) over its strongest oxyanion competitor, phosphate. The optimal loadings of each active component (Cu(II) and n-TiO2) will be determined in order to maximize both photo-oxidative and selective adsorptive performance. Then, the Fenton-like oxidation of As(III) to As(V) by Cu(II)-chitosan without n-TiO2 and UV will be examined. Finally, transition metal chitosan complexes (TMCs) of varying charge and valence will be systematically examined, their use as selective adsorbents for both As(V) and As(III) over phosphate evaluated, and the mechanism of arsenic adsorption by the TMCs determined. Ultimately, this dissertation finds that Fe(III)-chitosan, due to its ability to form strong inner-sphere complexes with both As(V) and As(III), even in the presence of phosphate is capable of selectively adsorbing both As(V) and As(III) without need for n-TiO2 and UV light to photo-oxidize As(III) into the more easily adsorbed As(V). The novel contributions of this dissertation not only present technologies capable of multifunctional and selective adsorption of arsenic over phosphate, they also develop a predictive understanding of selective adsorption. This knowledge can be applied to target other contaminants of interest in the future, both organic and inorganic.
