Book excerpt: DEPUIS LA PREMIERE DECOUVERTE SPECTACULAIRE D'EMISSION HYDROTHERMALE SUR LA RIDE DES GALAPAGOS EN 1977, PLUS D'UNE TRENTAINE DE SITES HYDROTHERMAUX ACTIFS EMETTANT DES FLUIDES ACIDES (PH = 24), DE HAUTE TEMPERATURE (> 300C) SONT ACTUELLEMENT CONNUS ET ETUDIES LE LONG DES DORSALES MEDIO-OCEANIQUES (MOR) ET DANS LES FOSSES ET BASSINS ARRIERE-ARC DE L'OUEST PACIFIQUE. CETTE ETUDE PRESENTE ET DISCUTE LA CHIMIE MINERALE DE FLUIDES HYDROTHERMAUX ISSUS D'ENVIRONNEMENTS GEOLOGIQUES VARIES DORSALE MEDIO-ATLANTIQUE (MAR) ; RIDE EST PACIFIQUE (EPR) ; BASSINS ARRIERE-ARC (BAB). LA VARIABILITE DE COMPOSITION CHIMIQUE OBSERVEE DANS CES FLUIDES EST ETROITEMENT CONTROLEE PAR LE PROCESSUS DE SEPARATION DE PHASES ET PAR L'INTERACTION FLUIDE - ROCHE SOUS DES CONDITIONS ELEVEES DE PRESSION ET TEMPERATURE. UNE ETUDE PLUS SPECIFIQUE A ETE ENTREPRISE SUR LE COMPORTEMENT GEOCHIMIQUE DES ELEMENTS TRACES ET DES TERRES RARES DANS LES FLUIDES HYDROTHERMAUX. LA DETERMINATION DE CES ELEMENTS A NECESSITE DES DEVELOPPEMENTS ANALYTIQUES PLUS POUSSES ASSOCIANT DES METHODES DE SEPARATION CHROMATOGRAPHIQUE A DES MESURES PAR SPECTROMETRIE DE MASSE A COUPLAGE PLASMA (ICP/MS). LES RESULTATS DE CES TRAVAUX MONTRENT QUE LES CONCENTRATIONS EN ELEMENTS TRACES DANS LE FLUIDES SONT FORTEMENT CONTROLEES PAR LES CARACTERISTIQUES PHYSICO-CHIMIQUES DU FLUIDES (PH, TEMPERATURE, CHLORINITE), PAR LE PROCESSUS DE SEPARATION DE PHASES ET PAR LA NATURE DE ROCHE LESSIVEE (ROCHES BASALTIQUES OU ULTRA-BASIQUES SUR LES DORSALES MEDIO-OCEANIQUES, ROCHES ACIDES DANS LES BASSINS ARRIERE-ARC). DE MEME, L'ETUDE MENEE SUR LES TERRES RARES SUGGERE QUE LEUR DISTRIBUTION DANS LES FLUIDES HYDROTHERMAUX DEPEND A LA FOIS DE L'INTERACTION DES FLUIDES AVEC LES PLAGIOCLASES, DE LA COMPLEXATION PAR LES IONS CL# ET DE LA FORMATION DE MINERAUX SECONDAIRES. D'AUTRE PART, LA PRESENCE D'UNE CONTRIBUTION MAGMATIQUE DANS UN SYSTEME HYDROTHERMAL PEUT FORTEMENT AFFECTER LE COMPORTEMENT DES ELEMENTS TRACES DANS LES FLUIDES. ENFIN, L'APPLICATION DES PROGRAMMES THERMODYNAMIQUES SUPCRT92 ET EQ3/6 A CES SYSTEMES HYDROTHERMAUX A PERMIS DE CONFIRMER LES CONCLUSIONS TIREES DES ETUDES GEOCHIMIQUES (DISTRIBUTION ET SPECIATION DES ELEMENTS, MINERAUX IMPLIQUES) ET DE MIEUX CONNAITRE LA GEOCHIMIE DES FLUIDES SOUS DES CONDITIONS ELEVEES DE PRESSION ET DE TEMPERATURE.

Book Synopsis Faecal Sludge Management by : Linda Strande
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.
Book Synopsis How to Design Wastewater Systems for Local Conditions in Developing Countries by : David M. Robbins
Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
