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: The impact of narrow pore size distribution (PSD) of activated carbon fibers (ACFs) on the oligomerization of phenolic compounds was conducted in this study. Four types of microporous ACFs with increasing degrees of activation, namely ACC-10 (8.0), ACC-15 (12.8), ACC-20 (17.4) and ACC-25 (19.7), and one granular activated carbon (GAC) F400 (4-800) were used as adsorbents. Seven commonly encountered phenolic pollutants were used as adsorbates - phenol, 2-methylphenol, 2-ethylphenol, 2-chlorophenol, 2-nitrophenol, 4-chlorophenol, and 4-nitrophenol. Single, binary and ternary adsorption of phenolic compounds were conducted under anoxic (absence of molecular oxygen) and oxic (presence of molecular oxygen) conditions. Single solute adsorption of phenolic compounds was found to be well described by Myers equation. For each adsorbate except nitrophenols, higher adsorptive capacities were achieved under oxic than anoxic conditions. The extent of oligomerization which was represented by the difference between the oxic and anoxic adsorptive capacity, were changing in the order of F400> ACC-25> ACC-20> ACC-15> ACC-10. This is in the same order as the decrease of the adsorbent pore diameter. At the same time, F400 showed least adsorption under anoxic conditions among all the adsorbents. The narrow PSD of ACFs was effective in hampering oligomerization in the single solute adsorption. Higher extraction efficiencies were achieved for ACFs than F400. The lower the extent of oligomerization, the higher regeneration efficiency was achieved. On each adsorbent, the extents of adsorbates oligomerization were related to the adsorbates critical oxidation potential (COP), molecular size, and adsorbent pore diameter. Low COP, small molecular size, large pore diameter always favored oligomerization. Binary adsorption for different phenolic compounds was conducted on ACC-10, ACC-15 and F400. No difference between anoxic and oxic binary adsorption isotherms were found on ACC-10. The Ideal Adsorbed Solution Theory (IAST), using the Myers equation for correlating the single-solute anoxic isotherms, successfully predicted the anoxic and oxic binary adsorption on ACC-10. For binary adsorption on ACC-15 and F400, the oxic adsorption was higher than anoxic ones and IAST well predicted the anoxic isotherms, but under predicted the oxic ones due to occurrence of oligomerization of the adsorbates on the adsorbent surface. The deviation of the experimental adsorption isotherms from predictions for F400 was larger than that of ACC-15. For binary adsorption, the narrow PSD of ACC-15 reduced the oligomerization to some extent while ACC-10 completely hampered oligomerization. For ternary adsorption on ACC-15 and F400, slight oligomerization was found on ACC-15 while obvious oligomerization of phenolic compounds was found on F400 under oxic conditions. Fourier Transform Infrared Spectroscopy (FT-IR) and solid nuclear magnetic resonance (NMR) were used to investigate the oligomerization of phenolic compounds on activated carbon. FT-IR and solid NMR results confirmed the oligomerization of phenolic compounds on the activated carbon surface under oxic conditions. To make GAC more cost-effective, novel ways to produce GAC - in the ways that ACFs were made - was proposed and tested. Experimental GAC, made from bituminous coal, successfully reduced oligomerization without losing any anoxic adsorptive capacity as compared to F400.

Available in PDF, EPUB and Kindle. Book excerpt: Adsorption Processes for Water Treatment discusses the application of adsorption in water purification. The book is comprised of 10 chapters that detail the carbon and resin adsorptive processes for potable water treatment. The text first covers the elements of surface chemistry and then proceeds to discussing adsorption models. Chapter 3 tackles the kinetics of adsorption, while Chapter 4 deals with batch systems and fixed fluid beds. Next, the book talks about the physical and chemical properties of carbon. The next two chapters discuss the adsorption of organic compounds and the removal of inorganic compounds, respectively. The eighth chapter presents operational, pilot plant, and case studies. Chapter 9 discusses the biological activated carbon treatment of drinking water, and Chapter 10 covers the adsorption of macroreticular resins. The book will be of great use to both researchers and professionals involved in the research and development of water treatment process.
