Download or read book Removal of Trace Organics from Groundwater Using Granular Activated Carbon Rocky Mountain Arsenal written by L. Hood and published by . This book was released on 1979 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: In accordance with recommendations put forth in the dept of the Army's report on carbon adsorption treatment of contaminated ground water at RMA. A full scale calgon adsorption unit was installed at rma and began operating in July 1978. To insure operation in compliance of the cease and desist orders by the state of Colorado dept of health, the unit has been running from July 1978 to the present. One of the prime objectives of the program of installation restoration is to acquire technology to develop and implement contaminant and treatment systems. To address this specific need at the rma site, calgon corp institute in its adsorption service contract an annual review of all data collected with a subsequent technical review of all the results obtained. It is the purpose of this report to review the operation of the adsorption system and the results obtained in light of previous treatability studies.

Book Use of Granular Activated Carbon and Carbon Block Filters at Municipal and Point of Use Drinking Water Treatment for Removal of Organics

Download or read book Use of Granular Activated Carbon and Carbon Block Filters at Municipal and Point of Use Drinking Water Treatment for Removal of Organics written by Harsh Satishbhai Ashani and published by . This book was released on 2017 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated carbon has been used for decades to remove organics from water at large scale in municipal water treatment as well as at small scale in Point of Use (POU) and Point of Entry (POE) water treatment. This study focused on Granular Activated Carbon (GAC) and activated Carbon Block (CB). This thesis has three related elements for organics control in drinking water. First, coagulation chemistry for Alum and Aluminum Chlorohydrate (ACH) was optimized for significant organics removal to address membrane fouling issue at a local municipal water treatment plant in Arizona. Second, Rapid Small Scale Column Tests were conducted for removal of Perfluorinated compounds (PFC). PFC were present in groundwater at a local site in Arizona at trace levels with combined concentration of Perfluorooctaneoic Acid (PFOA) and Perfloorooctanesulfonic Acid (PFOS) up to 245 ng/L. Groundwater from the concerned site is used as drinking water source by a private utility. PFC Removal was evaluated for different GAC, influent concentrations and particle sizes. Third, a new testing protocol (Mini Carbon Block (MCB)) for bench scale study of POU water treatment device - specifically carbon block filter - was developed and evaluated. The new bench scale decreased the hydraulic requirements by 60 times approximately, which increases the feasibility to test POU at a lab scale. It was evaluated for a common POU organic contaminant: chloroform, and other model contaminants. 10 mg/L of ACH and 30 mg/L of Alum with pH adjustment were determined as optimal coagulant doses. Bituminous coal based GAC was almost three times better than coconut shell based GAC for removing PFC. Multiple tests with MCB suggested no short circuiting and consistent performance for methylene blue though chloroform removal tests underestimated full scale carbon block performance, but all these tests create a good theoretical and practical fundamental for this new approach and provides directions for future researchers.

Book Use of Granular Acivated Carbon to Remove Trace Organics from the Effluent of a Class B Refinery

Download or read book Use of Granular Acivated Carbon to Remove Trace Organics from the Effluent of a Class B Refinery written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent study by Raphaelian and Harrison (1978) at SOHIO's Toledo refinery demonstrated that the activated sludge biological treatment system reduced concentrations of trace organic compounds in the waste water by over 99%. Addition of a pilot-scale mixed media filter and granular activated carbon (GAC) filter produced additional removals ranging from 12 to 98% for those compounds that could be quantified. The estimated cost of adding a full-scale GAC system to the SOHIO refinery is $6,800,000. The yearly operational cost for an 8.6 MGD flow is $1,720,000, including amortization, and the annual energy requirement is estimated at 12.775 x 106 kwh(e); this is equivalent to 2.2 x 104 bbl crude oil, or 0.0503% of average annual refinery throughput.

Book Effects of Activated Carbon Characteristics on Organic Contaminant Removal

Download or read book Effects of Activated Carbon Characteristics on Organic Contaminant Removal written by Detlef R. U. Knappe and published by IWA Publishing. This book was released on 2004-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many water treatment plants need to remove objectionable trace organic compounds, and activated carbon adsorption is often the best available technology. Utilities face the challenge of having to choose from a large variety of activated carbons, and iodine number or BET surface area values are often utilized in the selection process. Although neither parameter correlates well with adsorption capacities, alternative activated carbon selection criteria based on fundamental adsorbent and adsorbate properties are lacking to date. The first objective of this research was to systematically evaluate the effects of activated carbon pore structure and surface chemistry on the adsorption of two common drinking water contaminants: the relatively polar fuel oxygenate methyl tertiary-butyl ether (MTBE) and the relatively nonpolar solvent trichloroethene (TCE). The second objective was to develop simple descriptors of activated carbon characteristics that facilitate the selection of suitable adsorbents for the removal of organic contaminants from drinking water.Originally published by AwwaRF for its subscribers in 2003 This publication can also be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below

Book Activated Carbon for Water and Wastewater Treatment

Download or read book Activated Carbon for Water and Wastewater Treatment written by Ferhan Cecen and published by John Wiley & Sons. This book was released on 2011-09-19 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides comprehensive coverage of technologies which integrate adsorption and biological processes in water and wastewater treatment. The authors provide both an introduction to the topic as well as a detailed discussion of theoretical and practical considerations. After a review of the basics involved in the chemistry, biology and technology of integrated adsorption and biological removal, they discuss the setup of pilot- and full-scale treatment facilities, covering powdered as well as granular activated carbon. They elucidate the factors that influence the successful operation of integrated systems. Their discussion on integrated systems expands from the effects of environmental to the removal of various pollutants, to regeneration of activated carbon, and to the analysis of such systems in mathematical terms. The authors conclude with a look at future needs for research and develoment. A truly valuable resource for environmental engineers, environmental and water chemists, as well as professionals working in water and wastewater treatment.
