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.

Book Synopsis In-Situ Regeneration of Granular Activated Carbon (GAC) Using Fenton's Reagents by : Carla De Las Casas
Download or read book In-Situ Regeneration of Granular Activated Carbon (GAC) Using Fenton's Reagents written by Carla De Las Casas and published by . This book was released on 2006 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fenton-dependent recovery of carbon initially saturated with one of several chlorinated aliphatic contaminants was studied in batch and continuous-flow reactors. A specialty carbon, URV-MOD 1 (Calgon) was employed to minimize non-productive H2O2 demand - that which does not yield hydroxyl or superoxide radicals. Enhancement of PCE degradation kinetics by ferric iron addition is limited by iron solubility, even at relatively low pH. Quinone addition increased the pseudo-first-order rate constant for PCE loss temporarily. Only copper addition sustainably enhanced the specific rate of PCE loss. For copper-to-iron molar ratios of 0.25 to 5, the pseudo-first-order rate constant for PCE transformation was increased by a factor of 3.5. It is apparent that the effect of copper addition on Fenton-dependent reaction rates is complex, and involves a shift in chemical mechanism, as indicated by the differing slopes in the Arrhenius plot (with and without copper).A mathematical model was developed to evaluate the effect of operational parameters ([Fe(III)]T:[H2O2]o ratio and pH) on degradation kinetics and optimize the PCE degradation process in homogeneous reaction mixtures. The model simulated experimental degradation of the organic target in a homogeneous Fenton-reaction system. The model requires further refinement to simulate Fenton's systems in which ions in solution (such as sulfate and chloride) play significant roles. In continuous-flow reactors, Fenton's reagents were cycled through spent GAC in columns to degrade one of seven chlorinated compounds tested. The contaminant with the weakest adsorption characteristics, methylene chloride, was 99% lost from the carbon surface during a 14-hour regeneration period. At the field site, the GAC was saturated with gases containing TCE and PCE from a soil vapor extraction (SVE) system. In the field, up to 95% of the sorbed TCE was removed from GAC during regeneration periods of 50-60 hours. Recovery of PCE-loaded GAC was significantly slower. Column experiments show that there is minimal loss of carbon adsorption capacity during Fenton treatment and that the rate of GAC regeneration is compound specific. Scoping-level cost estimates indicated that field use of Fenton regeneration is not cost effective without optimization and/or iron surface amendments, except in the case of the most soluble VOCs.

This book was released on 2007 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fenton-dependent recovery o fcarbon initially saturated with one of several chlorinated aliphatic contaminants was studied in batch and continuous-flow reactors. A specialty carbon, URV-MOD 1 (Calgon) was employed to minimize non-productive H2O2 demand - that which does not yield hydroxyl or superoxide radicals. Because the reductive reaction of Fe(III) to Fe(II) limits the overall rate of radical generation via Fenton's mechanism, it was hypothesized that steps designed to increase the rate of ferrous iron generation would accelerate Fenton-dependent contaminant destruction, enhancing carbon recovery kinetics. Homogeneous-phase experiments were designed to establish the effects on PCE destruction kinetics of total iron concentration and additions of NH2OH, various quinones or copper to the Fenton mixtures.
