Book Description
Trinitrotoluene (TNT) and cyclotrimethylenetrinitramine (RDX), pink water, adsorption/solvent desorption cycling of activated carbon (FS300) has been studied as a function of various pretreatments. In agreement with previous studies of TNT and RDX individually, preferential plugging of pores by pretreatments did not improve the solvent regeneration of the FS300. The study of the competitive adsorption of TNT and RDX indicated that, at the higher concentrations, TNT tended to displace RDX from the carbon surface. This is attributed to a lower binding energy of the adsorbed RDX to the surface. In conjunction with water adsorption/desorption isotherms, the characteristics of a carbon with improved cycling properties have been elucidated. These properties are in agreement with those characteristics found in previous studies and involve a shift to a larger pore volume, increased concentration of pores in the mesopore range and an increased ratio of pore opening to pore body diameters. Another desirable property would be a lower adsorption binding energy for these explosives to the activated carbon.

Book Description
High surface area, a microporous structure, and a high degree of surface reactivity make activated carbons versatile adsorbents, particularly effective in the adsorption of organic and inorganic pollutants from aqueous solutions. Activated Carbon Adsorption introduces the parameters and mechanisms involved in the activated carbon adsorption

Book Description
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.
Optimization of the Regeneration Procedure for Granular Activated Carbon

Book Description
Laboratory scale experiments were conducted on the regeneration of activated carbons spent in tertiary treatment of wastewater. Wet spent carbon being regenerated thermally undergoes three regeneration stages: drying at about 220°F; Pyrolysis of the adsorbed pollutants at 500 to 1550°F; and Activation with flue gas and steam at 1600 to 1700°F. Data indicated that alkaline and iron oxide ash accumulation catalyze the oxidation of carbon pores. Leaching with HCl was found to remove the metallic elements and allow regeneration to proceed with less destruction of the carbon. Other observations are discussed.
