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: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book excerpt: More than 10 years after the "First European Symposium on Organic Micropollutants in the Aquatic Environment", the "Sixth Symposium" was held in Lisbon (Portugal) from 22 to 24 May 1990. The Symposium was organised within the framework of the Concerted Action COST 641 * which is included in the Fourth R&D Programme on the Environment of the Commission of the European Communities expiring at the end of 1990. After restructuring the Concerted Action in 1984, particular attention has been devoted to fate and transformation of organic micropollutants in the aquatic environment. Therefore, a major aim of the Symposium was to review current studies and progress in these areas, besides more general aspects related to analytical methodologies and behaviour of pollutants during water treatment processes. This volume contains the plenary papers presented in the following sessions at the Symposium: - Multidisciplinary studies - Partitioning of organic micropollutants in the aquatic environment - Novel analytical techniques in environmental chemistry - Monitoring micropollutant - Degradation of organic micropollutants during field conditions - Reclamation of polluted ground water - Chemical and photochemical oxidation - Future of environmental chemistry. In addition, extended versions of posters are included, covering the four topics which are dealt within the four Working Parties forming the structure of the Concerted Action: 1. Analytical methodologies 2. Transport and distribution 3. Transformation reactions 4. Water treatment. We believe that the Proceedings give a good overview of current activities in these fields of research in Europe.

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

Available in PDF, EPUB and Kindle. Book excerpt: This new edition of a classic text has now been extensively updated to include the latest developments in risk analysis and water quality assessment and management. It takes into account the role of ecological water quality in integrated regional and transboundary water resources management, according to the latest UNESCO programmes and the new EU-Water Framework Directive. This practice-oriented textbook is a unique tool for identifying and evaluating local and regional environmental risks from pollution hazards in groundwater, river water and coastal seawaters. The book explains different risk-based probabilistic methodologies and fuzzy logic-based approaches and includes various mathematical models for water quality simulation and theories, such as the decision analysis, the utility theory and the integrated risk-based multi-criteria assessment and management, in order to thoroughly evaluate several case studies from the real world. Questions testing the reader?s understanding are given at the end of each chapter, and a useful appendix provides hints for answering them as well the solutions themselves.

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.

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.
