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

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.

Available in PDF, EPUB and Kindle. Book excerpt: Granular activated carbon (GAC) has been specified as the best available technology (BAT) for the removal of synthetic organic compounds from drinking water. Drinking water utilities which use GAC must either replace or regenerate the carbon periodically. Thermal regeneration is one option for handling spent carbon. The effect of several parameters on volume losses and on the recovery of adsorption capacity of granular activated carbon (GAC) during thermal regeneration has been studied. Parameters investigated during this study include the temperature of the regeneration step, the time of regeneration, the type of oxidant, and the oxidant flow rate. The apparent (bulk) density was found to be a good parameter for monitoring thermal regeneration. Other carbon properties followed during regeneration include the surface area (determined by nitrogen isotherm), the micropore volume and the mesopore volume. Optimum regeneration conditions were found to be dependant on the type of GAC being regenerated. The effect of multiple regenerations on carbon properties is discussed.

This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Powdered activated carbon (PAC) is commonly used in drinking water treatment plants to control taste and odor, and it is available to remove synthetic organic chemicals (SOCs) that must be controlled to meet drinking water standards. The objective of this study was to show how the adsorptive properties of PAC could more effectively be used in both conventional and unconventional treatment processes to control organic compounds. A major finding of this study involved the competitive effect of natural organic matter (NOM) on the the adsorption of organic compounds on activated carbon. Isotherm data show that the adsorption capacity of a compound is highly dependent on the initial compound concentration due to the competition of NOM for adsorption sites on the surface of the carbon. The equilibrium carbon capacity at a certain aqueous concentration decreases with decreasing initial organic compound concentration in the isotherm test when the initial NOM concentration is constant. An easy-to-use method was developed in this study to determine the isotherm of an organic compound when present in natural water at any initial concentration. The method approximates the complex mixture of NOM as a single compound referred to as the equivalent background compound (EBC). The initial concentration and single solute isotherm constants of the EBC are solved for based on the NOM's competitive effect on the adsorption of the organic compound on activated carbon, and these data can be used to accurately predict the adsorption capacity for conditions of relevance in operating plants. The performance of PAC in a floc-blanket reactor (FBR) for the adsorption of TCP, NOM and trichloroethylene (TCE) from natural water was investigated. Laboratory and field data were collected. PAC residence times as high as 30 hrs can be achieved in the floc blanket under laboratory conditions. Comparison of the PAC adsorption capacity in the reactor to the equilibrium adsorption capacity of TCP, TCE, and NOM in central Illinois groundwater and surface water showed that full utilization of the adsorption capacity of the carbon can be achieved with such high residence times. However, the PAC performance has to be compared to an isotherm conducted with an initial SOC concentration comparable to the SOC concentration in the influent to the reactor. This is due to the finding of decreasing isotherm capacity with decreasing initial concentration.

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"--
