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.

Available in PDF, EPUB and Kindle. Book excerpt: First published for AWWRF members only in August, 2011, this research project conducted by AWWRF was done to in order to develop a UV disinfection knowledge base that utilities, engineers, and regulators can use to reduce the risks and costs of applying this technology. The survey data for this knowledge base was collected during the spring of 2008 and analyzed in order to develop conclusions and recommendation. 161 utilities in Canada and 148 in the United States have installed or are implementing drinking water UV disinfection. The complete database, including access to raw data and software tools, is included in this report on a CD ROM.

This book was released on 2017-11-22 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several general books are available on ultraviolet light and its applications. However, this is the first comprehensive monograph that deals with its application to water and wastewater treatment. There is a rapidly growing interest in using UV light in water sanitation due to the increased knowledge of the potential health and environmental impacts of disinfection byproducts. Ultraviolet Light in Water and Wastewater Sanitation integrates the fundamental physics applicable to water and wastewater sanitation, the engineering aspects, and the practical experience in the field. The text analyzes the concerns associated with this application of UV light and brings together comprehensive information on the presently available UV technologies applicable to water and wastewater treatment including: lamp technologies, criteria of evaluation and choice of technology; fundamental principles; performance criteria for disinfection; design criteria and methods; synergistic use of UV and oxidants (advanced oxidation); and functional requirements and potential advantages and drawbacks of the technique. Ultraviolet Light in Water and Wastewater Sanitation is the only treatise currently available combining fundamental knowledge, recommendations for design, evaluations of performance, and future prospects for this application. Water and wastewater treatment professionals, water utility employees, governmental regulators, and chemists will find this book an essential and unique reference for a technology which has received growing regulatory acceptance.

Book excerpt: "UV light is usually delivered to drinking water as it flows through a UV reactor (Chapter 5 gives more description of the design of UV reactors). The UV equipment (including one or more UV reactors) is typically applied to filtered water and is often installed after the filter effluent piping recombining before the clearwell. It is very important that the operators are able to control the UV output in the reactor so that at least a minimum UV dose is applied at all times"--
