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 Phenol Oxidation on the Surface of Granular Activated Carbon Under Water Treatment Conditions written by Lina Su Chin and published by . This book was released on 1989 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical activity of granular activated carbon (GAC) toward adsorbed phenol were investigated in a fixed bed column. After adsorption from aqueous solution, phenol was oxidized to carbon-carbon (C-C) and carbon-oxygen (C-O) bonded dimers as well as an oxidized compound of uncertain structure (molecular weight 276) as major products. This phenol coupling oxidation was observed on several types of commercial GAC. Various experimental parameters were tested to further characterize the coupling reaction of phenol on F400 GAC. Total product yields (based on adsorbed phenol) were determined based on the amount of phenol removed by GAC, not the initial concentration of input phenol. The ratio of C-C dimer to C-O dimer increased with the increase of the amount of phenol adsorbed. Also, total product yield was dependent on reaction pH which influenced phenol adsorption onto GAC from aqueous solution. Phenol oxidations on GAC surfaces were also studied in a series of experiments under conditions similar to those commonly met in water treatment. The presence of humic substances from soil or groundwater inhibited phenol oxidation and favored the formation of the C-O dimer relative to the C-C dimer. The lower total product yield was partially due to the competitive adsorption on active sites and partially to the free radical quenching activity of humic substances. The mechanism of the inhibition of humic substance has been discussed according to the results from syringic acid as a model compound of humic substances and ascorbic acid as a hydrophilic free radical scavenger, which were applied along with phenol onto GAC separately. Free chlorine-oxidized GAC showed less capacity for phenol adsorption than virgin GAC. The lower degree of phenol uptake resulted in lower formation of phenol coupling products on the GAC. However, application of free chlorine solution to the humic substance-loaded GAC restored the ability of the GAC to promote oxidation of adsorbed phenol. With or without the presence of humic substances, no data indicated that free chlorine-treated GAC produced higher yield of dimers, in comparison to similar experiments in which virgin carbon was used. In experiments with used carbons taken from the filters of water treatment plants, analyses of phenolic products were hindered by the complex gas chromatograms observed after these carbons were treated with phenol solutions. The removal of adsorbed material on used GAC by CH$sb3$OH and CH$sb2$Cl$sb2$ extraction, however, improved the ability of used carbon to promote phenol oxidation.

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.

Book excerpt: The present book discusses the principal lignocellulosic precursors used in the elaboration of activated carbons in different countries such as Asia, America, Europe and Africa; the different methods and experimental conditions employed in the synthesis of activated carbons, including one analysis of the principal stages of the preparation such as carbonization and activation (i.e., chemical or physical activation). Also, the recent and more specialized techniques used in the characterization of activated carbons are discussed in this book. For example, the techniques employed to determine textural parameters (mercury porosimetry and gas adsorption isotherms at 77 K) and different spectroscopies to determine chemical functionality (Raman, FT-IR, etc.) and other X-Ray techniques. Additionally, an overview of the application of activated carbons obtained from lignocellulosic precursors for wastewater treatment. Specifically, the analysis and discussion are focused on the advantages and capabilities of activated carbons for the removal of relevant toxic compounds and pollutants from water such as heavy metals, dyes, phenol, etc. Finally, the use of pyrolysis method for the valorization of two Mexican typical agricultural wastes (orange peel and pecan nut shell) for energy and carbon production is considered in this book.
