This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'électrocoagulation permet d'éliminer simultanément un large spectre de polluants organiques et minéraux, de colorants et de métaux lourds ; de ce fait, il a été beaucoup étudié. En revanche, peu de travaux ont été entrepris pour étudier de façon plus approfondie son fonctionnement. La complexité des effluents pour laquelle il est particulièrement intéressant d'utiliser ce procédé, fait aussi qu'il est difficile d'analyser les résultats. Cette thèse a pour objectif d'apporter une contribution à la compréhension du couplage électrocoagulation - décantation et des interactions liés à des effluents multi-polluants complexes. De plus l'aspect réacteur en continu a été abordé dans le cas d'un effluent synthétique simple pour mieux appréhender les différences par rapport au fonctionnement en discontinu. Cette étude est basée sur une approche systématique qui repose sur les processus élémentaires de l'électrocoagulation: Electrochimie, Coagulation et Séparation physique. Chaque processus fournit une base pour l'étude des interactions qui permettent ensuite la modélisation globale des processus. Afin d'étudier les couplages électrocoagulation-décantation, des effluents textiles industriels ont été traités par électrocoagulation suivie par une étape de décantation en éprouvette, sans agent floculant. L'effet des paramètres d'électrocoagulation sur la décantabilité des effluents traités et l'efficacité d'élimination de la pollution a été étudié en suivant en particulier la vitesse de décantation en éprouvette et en calculant le SVI. Le deuxième objectif de ce notre travail était d'étudier les couplages entre les différents types de pollution à éliminer et plus particulièrement un effluent de papeterie contenant des pollutions organiques et de l'arsenic. Enfin, nous avons réalisé une étude sur les performances du couplage EC-décantation pour le traitement d'un effluent synthétique textile en réacteur continu. Ce dernier est composé de deux éléments, la cellule électrochimique suivie d'une chambre de sédimentation.

Download or read book Electrochemistry for the Environment written by Christos Comninellis and published by Springer Science & Business Media. This book was released on 2009-10-15 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment technology is undergoing a profound transformation due to the fundamental changes in regulations governing the discharge and disposal of h- ardous pollutants. Established design procedures and criteria, which have served the industry well for decades, can no longer meet the ever-increasing demand. Toxicity reduction requirements dictate in the development of new technologies for the treatment of these toxic pollutants in a safe and cost-effective manner. Fo- most among these technologies are electrochemical processes. While electrochemical technologies have been known and utilized for the tre- ment of wastewater containing heavy metal cations, the application of these p- cesses is only just a beginning to be developed for the oxidation of recalcitrant organic pollutants. In fact, only recently the electrochemical oxidation process has been rec- nized as an advanced oxidation process (AOP). This is due to the development of boron-doped diamond (BDD) anodes on which the oxidation of organic pollutants is mediated via the formation of active hydroxyl radicals.

Download or read book Advanced Oxidation Processes for Water and Wastewater Treatment written by Simon Parsons and published by IWA Publishing. This book was released on 2004-03-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The suitability of Advanced Oxidation Processes (AOPs) for pollutant degradation was recognised in the early 1970s and much research and development work has been undertaken to commercialise some of these processes. AOPs have shown great potential in treating pollutants at both low and high concentrations and have found applications as diverse as ground water treatment, municipal wastewater sludge destruction and VOCs control. Advanced Oxidation Processes for Water and Wastewater Treatment is an overview of the advanced oxidation processes currently used or proposed for the remediation of water, wastewater, odours and sludge. The book contains two opening chapters which present introductions to advanced oxidation processes and a background to UV photolysis, seven chapters focusing on individual advanced oxidation processes and, finally, three chapters concentrating on selected applications of advanced oxidation processes. Advanced Oxidation Processes for Water and Wastewater Treatment will be invaluable to readers interested in water and wastewater treatment processes, including professionals and suppliers, as well as students and academics studying in this area. Dr Simon Parsons is a Senior Lecturer in Water Sciences at Cranfield University with ten years' experience of industrial and academic research and development.

Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.

Available in PDF, EPUB and Kindle. Book excerpt: This book originated out of the papers presented at the special symposium, "Electrochemistry in Transition-From the 20th to the 21st Century," scheduled by the Division of Colloid and Surface Science during the American Chemical Society meeting in Toronto. The symposium was in honor of Professor J. O'M. Bockris, who received the ACS award on "The Chemistry of Contemporary Technological Problems" (sponsored by Mobay Corporation) during this meeting and who also reached his 65th birthday in the same year. The symposium was of a multidisciplinary nature and encompassed the fields of theoretical and experimental elec trochemistry, surface science, spectroscopy, and electrochemical technology. The symposium also had an international flavor in that the participants represented several countries Australia, Belgium, Canada, Chile, England, Japan, Korea, the Netherlands, Poland, Switzer land, Venezuela, Yugoslavia, and the United States. The symposium was graciously sponsored by the ACS (Petroleum Research Fund and Division of Colloid and Surface Science), Alcan International, Dow Chemical Company, EG&G, Electrolyzer Corporation, Exxon, General Electric Company, IBM, Institute of Gas Technology, International Association of Hydrogen Energy, Johnson Matthey, Inc. , Kerr-McGee Corporation, Medtronics, and Texas A&M University (Center for Electrochemical Systems and Hydrogen Research and the Hampton Robinson Fund). The "theme" of the papers presented at the symposium covered not only significant contributions made to electrochemistry in the twentieth century, but also "New Horizons in Electrochemistry" for the twenty-first century. Thus, the scientists who presented papers were invited to contribute chapters to this book, having the same titles as the symposium.
