Download or read book Evaluation du procédé UV/H2O2 pour la désinfection et l'élimination des micropolluants en vue d'une réutilisation des eaux usées traitées en petites stations d'épuration written by Bruno Cédat and published by . This book was released on 2016 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans un contexte de raréfaction de la ressource en eau, le traitement des eaux usées peut permettre de constituer des réserves d'eau durables et valorisables pour des usages variés tels que l'irrigation des cultures, la recharge de nappe phréatique ou encore une utilisation directe par les industries grandes consommatrices d'eau (cimenterie, aciéries...). Ainsi, la nécessité d'améliorer le traitement des eaux usées en sortie de STEU devient primordial afin d'assurer une qualité chimique et microbiologique de l'eau compatible avec sa réutilisation. Le traitement des micropolluants constitue notamment un nouveau défi pour les STEU. Si des projets de recyclage des eaux usées émergent pour les grandes STEU, le potentiel des petites ou moyennes STEU, qui constituent près de 90% des installations en France, reste inexploité à l'heure actuelle. Pour y remédier, les procédés d'oxydation avancée, notamment ceux basés sur l'UV, se présentent comme des solutions de traitement prometteuses. L'objectif de cette étude est de démontrer que la technologie UV/H2O2 est efficace et économiquement réaliste pour la désinfection et l'élimination des micropolluants organiques dans ces petites et moyennes STEU. Dans une première phase, un pilote de laboratoire UV/H2O2 a été évalué en conditions réelles (débit, matrice) sur des modèles bactériens et sur des micropolluants estrogéniques (E1, E2 et EE2) dans les eaux usées traitées d'une STEU. L'efficacité du traitement est comparée à celle de la photolyse seule. Il a été montré que le traitement UV/H2O2 permet une amélioration de la désinfection en assurant une destruction des bactéries contrairement à la photolyse seule qui ne fait qu'inactiver les micro-organismes. D'autre part, les doses UV (plus petit 600 mJ/cm2) et les concentrations en H2O2 étudiées (30-50 mg/L d'H2O2) permettent d'abattre plus de 80% de l'ensemble des micropolluants ciblés et de l'activité biologique (estrogénicité) associée, sans former de sous-produits estrogéniques ou toxiques au regard des tests d'activité employés dans l'étude (YES et Vibrio Fisheri). Parallèlement, il a été montré que le procédé UV/H2O2 est également efficace pour éliminer plus de 70% des produits pharmaceutiques (diclofénac, ibuprofène et naproxène) à 1000 mJ/cm2. Sur la base des paramètres de traitement établis en pilote de laboratoire, un prototype a été dimensionné pour la STEU de Vercia (filtre planté de roseaux, 1100 EH, Jura). Les conditions de traitement mises en œuvre (dose UV plus pertit 1000 mJ/cm2, [H2O2] = 15 mg/L) ont permis d'obtenir une eau de très haute qualité bactériologique et des abattements des micropolluants suivis supérieurs à 90%. Cette expérimentation à échelle réelle a permis d'estimer le coût global de cette technologie à environ 0,28 €/m3. L'ensemble de ce travail de recherche conclue à l'efficacité et au fort potentiel de la technologie UV/H2O2 pour le recyclage des eaux usées traitées des petites et moyennes STEU.

Download or read book Optimisation multivariée d'un traitement des eaux usées par DEL-UV en vue d'une réutilisation pour l'irrigation written by Anne-celine Chevremont and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le développement de nouvelles technologies pour le recyclage des eaux usées est une priorité pour les régions arides et semi-arides tels que les pays du bassin méditerranéen. L'objectif de ce travail a été, dans un premier temps, de développer un système de traitement tertiaire des eaux usées en testant l'efficacité de diodes électroluminescentes émettant des UV-A et/ou des UV-C (DEL-UV) sur l'inactivation de souches bactériennes indicatrices de pollution fécale (Escherichia coli et Enterococcus faecalis) puis sur des effluents urbains, en étudiant la diminution des pollutions microbiennes et chimiques. Cette première étape a mis en évidence l'efficacité accrue du couplage UV-A et UV-C, permettant d'obtenir une eau de qualité répondant aux exigences législatives relatives à la réutilisation des eaux usées pour l'irrigation. La deuxième partie de ce travail était l'étude de l'impact de l'arrosage avec des eaux usées traitées par DEL-UV sur les paramètres du sol et sur le devenir de certain polluant aromatiques dans les sols (anthracène et carbamazépine). L'arrosage avec des eaux usées traitées par DEL-UV ne modifie pas la composition chimique de la matière organique de sol, l'activité catabolique globale des microorganismes, et le nombre et la diversité de bactéries indicatrices de pollution fécale par rapport au sol arrosé avec de l'eau d'irrigation. Certaines activités enzymatiques liées à la dégradation de la matière organique augmentent dans les sols arrosés avec des eaux usées traitées par DEL-UV, montrant que la matière organique apportée par l'effluent est activement dégradée par les microorganismes.

Book excerpt: This book is the first to explore the distribution, fate, and ecology of phage in the environment and point up the important applications of this information. The text begins with an historical overview, followed by a discussion of the current state of phage taxonomy. Next is covered the distribution patterns and fate of phage in diverse environments, e.g. soil, fresh water, marine water, and water and wastewater treatment plants. Factors that can influence the numbers and activity of phage populations, e.g. host and phage density, association of a phage with solids, presence of organic matter, temperature, pH, ultraviolet and visible light, concentration and types of ions present, and the metabolic activities of bacteria other than the phage host are examined. One chapter is devoted to the occurrence and implications of phage in various industries, e.g. dairy, wine, sausage, and antibiotic industries.

Download or read book Drinking Water Microbiology written by Gordon A. McFeters and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microbiology of drinking water remains an important worldwide concern despite modem progress in science and engineering. Countries that are more technologically advanced have experienced a significant reduction in water borne morbidity within the last 100 years: This reduction has been achieved through the application of effective technologies for the treatment, disinfec tion, and distribution of potable water. However, morbidity resulting from the ingestion of contaminated water persists globally, and the available ep idemiological evidence (Waterborne Diseases in the United States, G. F. Craun, ed. , 1986, CRC Press) demonstrates a dramatic increase in the number of waterborne outbreaks and individual cases within the United States since the mid-1960s. In addition, it should also be noted that the incidence of water borne outbreaks of unknown etiology and those caused by "new" pathogens, such as Campylobaeter sp. , is also increasing in the United States. Although it might be debated whether these increases are real or an artifact resulting from more efficient reporting, it is clear that waterborne morbidity cannot be ignored in the industrialized world. More significantly, it represents one of the most important causes of illness within developing countries. Approxi mately one-half the world's population experiences diseases that are the direct consequence of drinking polluted water. Such illnesses are the primary cause of infant mortality in many Third World countries.
