Download or read book Ozone in Water Treatment written by Bruno Langlais and published by Routledge. This book was released on 2019-07-16 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of the Safe Drinking Water Act Amendments of 1986, many water utilities are reexamining their water treatment practices. Upcoming new regulations on disinfection and on disinfection by-products, in particular, are the primary driving forces for the big interest in ozone. It appears that ozone, with its strong disinfection capabilities, and apparently lower levels of disinfection by-products (compared to other disinfectants), may be the oxidant/disinfectant of choice. Many utilities currently using chlorine for oxidation may need to switch due to chlorine by-product concerns. Utilities using chloramines may need to use ozone to meet CT requirements. This book, prepared by 35 international experts, includes current technology on the design, operation, and control of the ozone process within a drinking water plant. It combines almost 100 years of European ozone design and operating experience with North American design/operations experience and the North American regulatory and utility operational environment. Topics covered include ozone chemistry, toxicology, design consideration, engineering aspects, design of retrofit systems, and the operation and economics of ozone technology. The book contains a "how to" section on ozone treatability studies, which explains what information can be learned using treatability studies, at what scale (bench, pilot, or demonstration plant), and how this information can be used to design full-scale systems. It also includes valuable tips regarding important operating practices, as well as guidance on retrofits and the unique issues involved with retrofitting the ozone process. With ozone being one of the hottest areas of interest in drinking water, this book will prove essential to all water utilities, design engineers, regulators, and plant managers and supervisors.

Book excerpt: Recent years have seen an expansion in speciality uses of activated carbons including medicine, filtration, and the purification of liquids and gaseous media. Much of current research and information surrounding the nature and use of activated carbon is scattered throughout various literature, which has created the need for an up-to-date comprehensive and integrated review reference. In this book, special attention is paid to porosities in all forms of carbon, and to the modern-day materials which use activated carbons - including fibres, clothes, felts and monoliths. In addition, the use of activated carbon in its granular and powder forms to facilitate usage in liquid and gaseous media is explored. Activated Carbon will make essential reading for Material Scientists, Chemists and Engineers in academia and industry. - Characterization of porosity - The surface chemistry of the carbons - Methods of activation and mechanisms of adsorptio - Computer modelling of structure and porosity within carbons - Modern instrumental analytical methods

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

This book was released on 2018-05-14 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thèse de Doctorat de l’année 2016 dans le domaine Chimie - Généralités, Université des sciences et techniques de Masuku (Université des Sciences et Techniques de Masuku de Franceville-Gabon, Ecole Doctorale des Sciences Fondamentales et Appliquees), langue: français, résumé: Ce travail a eu pour thème central les charbons actifs, un adsorbant jouant un rôle fondamental dans l’élimination en solution aqueuse des cations Mn (II) et Al (III), puis des substances humiques. Dans le souci de valoriser les déchets des coques de noix de coula edulis (noisetier d’Afrique), la première phase de cette étude a été consacrée à la préparation et à la caractérisation physico-chimique des charbons actifs. Les propriétés surfaciques étudiées à l'aide de l’Infrarouge à Transmission de Fourier (IRTF), titrage de Boehm, la détermination du pHPCN et l'évaluation des surfaces spécifiques par adsorption de l'iode, le bleu de méthylène et/ou l'acide acétique. Les résultats des spectres infrarouges ont montré respectivement la présence des groupements -C-C-, -C-O-, -C = C- et -C = O. La titration de Boehm a prouvé que l'acidité totale était supérieure à basicité totale. Les valeurs de pH de charge zéro ont été inclus entre 2 et 3,5. Les surfaces spécifiques obtenues par adsorption diminué dans l'ordre de l'iode, l'acide acétique et le bleu de méthylène classant par ordre de prépondérance les micro, méso et macro pores sur leurs surfaces. Enfin l utilisation des charbons actifs obtenus pour éliminer les cations Mn (II) et Al (III), puis les substances humiques en solution aqueuse en mode batch en faisant varier les paramètres tels que le pH, la concentration initiale, le temps de contact, la température, la masse du charbon actif et sa granulométrie. Ces résultats ont révélé que l'adsorption des ions Mn (II), Al (III) et des substances humiques est fortement dépendante du pH. Les données expérimentales ont montré que l’adsorption des ions Mn (II) est suivie par les isothermes de Langmuir et de Freundlich et celle des ions Al (III) et des substances humiques par l’isotherme de Langmuir. L’étude cinétique a montré que les réactions d’adsorption des ions Mn (II) et Al (III) sont suivies par le modèle du pseudo-second ordre, alors que celle des substances humiques est suivie par le modèle du pseudo-premier ordre et caractérisée par un mécanisme de transfert de masse externe. L’étude thermodynamique a montré que l’adsorption des ions Mn (II) et des substances humiques est spontanée, l’adsorption des ions manganèse est endothermique sur le charbon actif, CAo, et exothermique sur les charbons actifs, CAH et CAZ, alors que celle des substances humique est endothermique à la surface de chaque charbon actif.

Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.
