Available in PDF, EPUB and Kindle. Book excerpt: "Many books have been written about granular activated carbon. Some focus on the theory of performance and removal mechanisms while others focus on design features. This book focuses on solutions. It describes the challenges facing water providers to provide safe water that is acceptable to their customers, utility experiences using activated carbon, activated carbon applications, and design and procurement approaches. The appendices include detailed case studies and a life-cycle assessment demonstrating favorable sustainability considerations for activated carbon when compared to other treatment technologies. Never before has all of this information been together in one location. The what, why, and how of activated carbon are connected in this book and demonstrate why this treatment technology has maintained its status as an integral treatment technology in the quest for pure water over millennia"--

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.

Download or read book Treatment of MTBE Contaminated Waters Using Air Stripping and Advanced Oxidation Processes written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of the fuel oxygenate methyl tert-butyl ether (MTBE) has led to the contamination of both surface and groundwater supplies. This study evaluates the treatment of MTBE contaminated drinking water using air stripping and advanced oxidation processes (AOPs) on a pilot scale. The treatment efficiency of the air stripper was evaluated at different air/water ratios ranging from 105:1 to 206:1. Although a treatment efficiency of>99% was achieved for each of the air/water ratio studied, the depth of the packing required to achieve this efficiency increased with decreasing air/water ratio. The adsorption studies conducted on MTBE laden off-gas from the air stripper showed that granular activated carbon (GAC) has a higher adsorptive capacity than the carbonaceous polymeric resin. Experiments conducted at different off-gas relative humidity (RH) of 20%, 30% and 50% reveal that the GAC adsorptive capacity decreased with increasing RH, whereas, the RH did not impact the resin adsorptive capacity. Ozone/hydrogen peroxide (O3/H2O2), ozone/UV (O3/UV), hydrogen peroxide/UV (H2O2/UV), and ozone/hydrogen peroxide/UV (O3/H2O2/UV) are the four AOPs evaluated in this study. An increase in the recycle ratio by 100% resulted in a 5% increase in the treatment efficiency. A treatment effectiveness of 98% was achieved with the use of O3/UV process at an O3 concentration of 5.8 mg/L. The experimental results have shown that the O3/H2O2 process is a slightly more effective (2 to 3% more) treatment process than the O3/UV process at the same O3 concentrations and a H2O2:O3 molar ratio of 1.4:1. Increased treatment efficiencies were observed with increasing H2O2:O3 molar ratios, with the optimum ratio for maximum treatment efficiency being 1:1. Non-detectable levels of MTBE were recorded in the O3/H2O2/UV process, at an O3 dosage of 5.8 mg/L and a H2O2:O3 molar ratio of 1.4:1. The O3/H2O2/UV process was more effective than the O3/H2O2 process at lower H2O2:O3 molar ratios and at ratios above 1:1, the difference in the treatment efficiencies was negligible. Tert-butyl formate, tert-butyl alcohol), methyl acetate and acetone were the major oxidation by-products identified in all the AOPS. The conducted cost analyses revealed that air stripping was the most cost effective treatment process compared to the AOPs.

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.
