Book Synopsis Biological Phosphate Removal from Wastewaters by : R. Ramadori
Download or read book Biological Phosphate Removal from Wastewaters written by R. Ramadori and published by Elsevier. This book was released on 2017-01-31 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Phosphate Removal from Wastewaters contains the proceedings of an International Association on Water Pollution Research and Control Specialized Conference held in Rome, Italy on September 28-30, 1987. Contributors review advances that have been made in the removal of biological phosphates from wastewaters, both at the fundamental scientific level and in the practical application of the process. Topics range from the fundamental microbiology and biochemistry of the enhanced biological removal of phosphate to the practical full-scale plant experiences with phosphorus removal and sludge handling from such processes. This text is comprised of 43 chapters; the first of which describes the utilization of polyphosphate as an energy reserve in Acinetobacter sp. and activated sludge. Attention then turns to metabolic control in polyphosphate-accumulating bacteria and its role in enhancing biological phosphate removal. The biochemistry and energetics of biological phosphorus removal are also considered. The next section is devoted to process modeling and includes chapters that explore the kinetics of biological excess phosphorus removal; factors affecting anaerobic stabilization during biological phosphorus removal; and the behavior of magnesium in biological phosphate removal. In the next section, bench/pilot-scale studies are presented; one of which investigated the reduction of returned phosphorus from a sludge treatment process. The book concludes with a discussion on phosphate removal mechanisms and pilot- and full-scale experiences. This book will be of interest to students, practitioners, and policymakers in water pollution control.
Book Synopsis Optimization and modeling of combined biological and physical-chemical phosphorus removal in wastewater treatment plants with intermittent aeration by : Erika Varga

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de la thèse est d'analyser les problèmes opérationnels et de modéliser l'élimination des nutriments dans les petites/moyennes installations qui mettent en œuvre une élimination combinée biologique et physico-chimique du phosphore. Le procédé étudié utilise une aération alternée optimisée pour une élimination complète de l'azote par nitrification et dénitrification, un système très représentatif en France. Comme une zone anaérobie est également présente, l'élimination biologique du phosphore est effectuée et combinée avec l'ajout de FeCl3 pour garantir que la qualité des effluents est conforme aux normes de l'UE. Afin de maximiser la fraction biologique de l'élimination du P, les paramètres d'aération et les temps de rétention aérobie/anoxique/anaérobie ont été analysés et optimisés par la programmation d'un système de contrôle automatisé. La libération de P secondaire lors de l'extraction intermittente des boues (et le retour de la liqueur de boue dans la zone anaérobie) a été observée. Une relocalisation du dosage de fer a été proposée du bassin d'aération vers spécifiquement la liqueur de boue avant son retour en tête. Ce changement permet à l'opérateur d'économiser sur les coûts des produits chimiques. Pour évaluer d'autres scénarios, des simulations ont été réalisées avec le logiciel Sumo. La simulation du procédé en fonctionnement régulier a mis en évidence quelques écarts de modélisation propres à ces conditions, à savoir les rejets de phosphore (en bassin non aéré et rejet secondaire lors de la déshydratation) et les transformations redox du Fer dans les boues activées. Plusieurs expériences spécifiques ont été menées pour répondre à ces questions. Comme la récupération du P est une préoccupation émergente (et mal mise en œuvre pour les usines de petite/moyenne taille), il est essentiel d'analyser ces interactions en détail afin de trouver un produit de récupération idéal pour chaque condition. Les boues physico-chimiques, contenant du fer, sont idéales pour la récupération de vivianite, pour laquelle une compréhension approfondie de la réduction du fer est essentielle. Cette thèse présente une étude complète des procédés de réduction du fer dans les boues activées. Avec les résultats des expériences, les observations dans l'installation et la littérature des recherches antérieures, des modifications/extensions au modèle ont été recommandées. Le modèle a été calibré par rapport à de nombreuses données de l'installation avec différentes conditions d'exploitation et des données mesurées à partir d'essais de réacteurs discontinus. Le modèle calibré peut simuler correctement le fonctionnement de l'installation dans différentes conditions et peut également être utilisé pour évaluer différents scénarios de traitement et de récupération.

Download or read book Activated Sludge and Aerobic Biofilm Reactors written by Marcos Von Sperling and published by IWA Publishing. This book was released on 2007-03-30 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated Sludge and Aerobic Biofilm Reactors is the fifth volume in the series Biological Wastewater Treatment. The first part of the book is devoted to the activated sludge process, covering the removal of organic matter, nitrogen and phosphorus.A detailed analysis of the biological reactor (aeration tank) and the final sedimentation tanks is provided. The second part of the book covers aerobic biofilm reactors, especially trickling filters, rotating biological contractors and submerged aerated biofilters. For all the systems, the book presents in a clear and informative way the main concepts, working principles, expected removal efficiencies, design criteria, design examples, construction aspects and operational guidelines. About the series: The series is based on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other titles in the series are: Volume 1: Waste Stabilisation Ponds; Volume 2: Basic Principles of Wastewater Treatment; Volume 3: Waste Stabilization Ponds; Volume 4: Anaerobic Reactors; Volume 6: Sludge Treatment and Disposal

This book was released on 1986 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation addressed the technical and economic feasibility ofretrofitting existing Canadian municipal wasterwater treatment plants forenhanced biological phosphorus removal (EBPR). Various EBPR processes werereviewed briefly and the practicality of using these technologies compared toconventional chemical precipitation technology for removing phosphorus frommunicipal wastewaters was assessed. An attempt was made to identify thetype and size of existing treatment plants in Canada that would be mostamenable to retrofit for enhanced biological phosphorus removal. Costs werecompared for a number of EBPR alternatives and chemical precipitation. Thisstudy was not limited to a single specific plant, but was conducted inbroader context so that those conditions under which either chemical orenhanced biological phosphorus removal was more cost-effective could beidentified.
