Book excerpt: LE SUIVI EN CONTINU DU FONCTIONNEMENT DES STATIONS D'EPURATION CONSTITUE UNE REPONSE ADAPTEE AUX NOUVEAUX IMPERATIFS DICTES PAR LES DIRECTIVES EUROPEENNES DANS LE DOMAINE DE L'ASSAINISSEMENT. L'EXIGENCE D'UNE QUALITE CONSTANTE DES TRAITEMENTS ET LA PRISE EN COMPTE DE TOUTES LES EAUX POLLUEES (DONT LES EAUX PLUVIALES) IMPOSENT UNE CONNAISSANCE ET UNE SURVEILLANCE PRECISES DES EFFLUENTS LE LONG DE LA FILIERE DE TRAITEMENT. SUIVRE LES EVOLUTIONS D'UN PROCEDE BIOLOGIQUE D'EPURATION PERMET PAR AILLEURS D'EN OPTIMISER L'EXPLOITATION. UN DES OBJECTIFS DE CETTE RECHERCHE EST D'ETUDIER LES METHODES D'ESTIMATION DE LA POLLUTION A L'AIDE DE MESURES TELLES QUE LA TURBIDITE OU LA CONDUCTIVITE. DES LOIS DE REGRESSIONS LINEAIRES SIMPLE OU MULTIPLE SONT UTILISEES. LA PRECISION DES CORRELATIONS DIRECTES ENTRE LA TURBIDITE ET LES PARAMETRES RECHERCHES EST CEPENDANT CONDITIONNEE PAR LA SENSIBILITE DE LA MESURE DE TURBIDITE VIS A VIS DE LA COLORATION DE L'EFFLUENT ET DE L'EVOLUTION DE LA REPARTITION GRANULOMETRIQUE DES PARTICULES EN SUSPENSION. DANS LE CAS DES EFFLUENTS D'ENTREE ET DE SORTIE DE STATION, LES ESTIMATIONS PEUVENT ETRE AMELIOREES PAR L'UTILISATION DE PLUSIEURS LOIS DE REGRESSION LINEAIRE : LES EFFLUENTS DIURNES COMPOSES D'UNE FRACTION INDUSTRIELLE, LES EFFLUENTS NOCTURNES DILUES PAR DES EAUX CLAIRES PARASITES, ET LES EFFLUENTS PAR TEMPS DE PLUIE FORTEMENT DILUES MAIS SINGULIEREMENT CHARGES PAR L'HYDROCURAGE DES RESEAUX. LES RESULTATS OBTENUS SUR LE SITE ETUDIE PRESENTENT DES ERREURS MOYENNES D'ESTIMATION DE 10% POUR LES MES ET 15% POUR LA DCO. PAR AILLEURS, LA MISE AU POINT D'UN DISPOSITIF AUTOMATISE A PERMIS D'ACCEDER AU SUIVI DE LA DECANTABILITE ET DE LA RESPIRATION DES BOUES ACTIVEES. OUTRE L'INTERET DE CES MESURES POUR LE SUIVI DU FONCTIONNEMENT DES OUVRAGES (BASSIN D'AERATION ET CLARIFICATEUR), CES DERNIERES ASSOCIEES A UNE MESURE DE TURBIDITE SONT UTILISEES COMME VARIABLES D'EQUATIONS LINEAIRES AFIN D'ESTIMER LES MES ET MVS. CECI PERMET DE TENIR COMPTE DES PERTURBATIONS INDUITES PAR L'ETAT DE FLOCULATION SUR LA MESURE DE TURBIDITE, ET DES VARIATIONS DU RAPPORT MES/MVS. LES ERREURS MOYENNES D'ESTIMATION OBTENUES SONT INFERIEURES A 8%. ENFIN LE DEVELOPPEMENT D'UN SYSTEME DE SUPERVISION SUR SITE A PERMIS DE VERIFIER LES POSSIBILITES OFFERTES PAR L'APPLICATION DE CES TRAVAUX DANS LE CADRE DE LA SURVEILLANCE ET DE L'ANALYSE DU FONCTIONNEMENT DES PROCEDES BIOLOGIQUES D'EPURATION.

This book was released on 1998 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les effluents de station d'épuration (STEP) se déversent continuellement dans les cours d'eau à l'aval des agglomérations. Si les effets des effluents dus aux matières organique et minérale sont relativement bien connus, on s'interroge encore sur l'impact des micropolluants. Pour caractériser l'impact d'un effluent de STEP, nous avons choisi une approche intégrée, combinant des analyses chimiques et des mesures biologiques sur les invertébrés et les poissons telles que des études de structure des communautés où l'utilisation de marqueurs morphologiques, physiologiques ou biochimiques. Les études in situ utilisées conjointement avec les mesures en conditions contrôlées nous ont permis de proposer un lien de cause à effet entre les potentialités toxiques d'un effluent et les perturbations observées sur l'écosystème. Un profil analytique et toxicologique de l'impact des effluents de STEP s'est dégagé de notre étude sur trois cours d'eau. Par les mesures in situ, nous avons mis en évidence l'impact de perturbations annexes et notamment de la pollution apportée par les déversoirs d'orage places sur le réseau d'assainissement et rejetant en amont de la STEP. Ce premier travail a confirmé l'importance des variations de l'impact des effluents de STEP et nous a conduit à prendre en compte le facteur temps sur un seul site d'étude. Grâce à l'utilisation de nombreuses méthodes, nous avons pu préciser l'impact d'un effluent. Des perturbations au niveau de la communauté d'invertébrés benthiques ont été mises en évidence et des relations ont pu être établies entre la présence de quelques contaminants et les effets constates. De plus, nous avons observé que l'impact le plus important, mesure en été, ne s'explique pas uniquement par une concentration plus élevée de l'effluent dans la rivière. Nous avons classé nos méthodes selon leur pouvoir de discrimination de l'effet mais aussi selon leur pertinence écologique, leur capacité à identifier les agents polluants et leur simplicité d'utilisation. De plus, grâce à notre classement des méthodes, nous proposons une démarche intégrée opérationnelle d'évaluation de l'impact d'un effluent de STEP qui combine la mesure d'un indice biologique global, le test de toxicité chronique sur cériodaphnie et la mesure de la concentration en ammonium.

This book was released on 2007 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les eaux usées générées par les activités humaines sont traitées dans les stations d’épuration et donnent des boues. Ces boues sont utilisées en épandage agricole lorsqu’elles répondent aux besoins des sols et des plantes sans porter atteinte aux santés humaines et animales ni à l’environnement. En effet, les boues de station d’épuration peuvent contenir différents types de polluants encadrés par la réglementation : éléments traces métalliques, les éléments traces organiques, bactéries, parasites, prions, et résidus médicamenteux. Dans ce travail, nous avons envisagé les éléments biologiques et minéraux persistants dans les boues de station d’épuration. L’évaluation du risque a été faite à partir des données sur leur devenir, leur toxicité et les risques de contamination des populations humaines et animales. L’épidémiosurveillance en place semble prouver que les mesures actuelles sont suffisantes en ce qui concerne les éléments minéraux et biologiques tels que virus, bactéries et parasites. Mais les critères de sécurité seront amenés à évoluer avec l’avancée des connaissances sur les voies de transmission et la rémanence des prions dans l’environnement. En ce qui concerne les résidus médicamenteux, leur devenir et leur impact dans les écosystèmes.

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: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In colonial Latin America, social identity did not correlate neatly with fixed categories of race and ethnicity. As Imperial Subjects demonstrates, from the early years of Spanish and Portuguese rule, understandings of race and ethnicity were fluid. In this collection, historians offer nuanced interpretations of identity as they investigate how Iberian settlers, African slaves, Native Americans, and their multi-ethnic progeny understood who they were as individuals, as members of various communities, and as imperial subjects. The contributors’ explorations of the relationship between colonial ideologies of difference and the identities historical actors presented span the entire colonial period and beyond: from early contact to the legacy of colonial identities in the new republics of the nineteenth century. The volume includes essays on the major colonial centers of Mexico, Peru, and Brazil, as well as the Caribbean basin and the imperial borderlands. Whether analyzing cases in which the Inquisition found that the individuals before it were “legally” Indians and thus exempt from prosecution, or considering late-eighteenth- and early-nineteenth-century petitions for declarations of whiteness that entitled the mixed-race recipients to the legal and social benefits enjoyed by whites, the book’s contributors approach the question of identity by examining interactions between imperial subjects and colonial institutions. Colonial mandates, rulings, and legislation worked in conjunction with the exercise and negotiation of power between individual officials and an array of social actors engaged in countless brief interactions. Identities emerged out of the interplay between internalized understandings of self and group association and externalized social norms and categories. Contributors. Karen D. Caplan, R. Douglas Cope, Mariana L. R. Dantas, María Elena Díaz, Andrew B. Fisher, Jane Mangan, Jeremy Ravi Mumford, Matthew D.

Book excerpt: Experimental microdosimetry deals with the measurement of charged particle energy deposition in tissue equivalent volumes, ranging in size from nanometres to micrometres. Microdosimetry is employed to improve our understanding of the relationship between radiation energy deposition, the resulting biological effects, and the appropriate quantities to be used in characterizing and quantifying radiation quality. Although many reviews and contributions to the field have been published over the past fifty years, this new book is the first to provide a single, up to date, and easily accessible account of experimental microdosimetry. This book is designed to be used in medical, radiation, and health physics courses and by Master's and PhD students. In addition to serving as an introductory text to the field for graduate students, this book will also be of interest as a teaching and reference resource for graduate supervisors and established researchers. Drs. Lennart Lindborg and Anthony Waker have spent a life-time career in experimental microdosimetry research in academic, industrial and regulatory environments and have observed the development of the field from its early days as a recognized discipline; they bring to this book particular knowledge and experience in the design, construction, operation and use of tissue equivalent gas ionization counters and chambers.
