This book was released on 2016 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Actualmente las estaciones depuradoras de aguas residuales (EDAR) urbanas están ampliamente implantadas en los países industrializados, puesto que es necesario realizar un tratamiento de las aguas residuales antes de verterlas al medioambiente. En los sistemas de tratamiento convencionales, los compuestos nitrogenados se eliminan mediante un tratamiento biológico de nitrificación autotrófica y desnitrificación heterotrófica, que garantiza una buena calidad del efluente. En estos tratamientos se necesita gran cantidad de aireación para la nitrificación y la mayoría de la materia orgánica del agua residual se destina a la desnitrificación en lugar de a la producción de biogás. Por tanto, las EDAR urbanas presentan un gran consumo energético y el principal reto en la actualidad es conseguir una depuradora urbana autosuficiente energéticamente. Una alternativa para conseguirlo es la implementación de la eliminación biológica autotrófica de nitrógeno (BNR) en la línea principal de aguas. El tratamiento consistiría en una primera etapa (A-Stage) en la cual se eliminaría toda la materia orgánica destinándola a la producción de biogás, y una segunda etapa (B-Stage) en la que se eliminaría el nitrógeno mediante el proceso BNR. El proceso BNR es un proceso en dos etapas. Primero, la mitad del amonio presente en el agua residual se oxida a nitrito mediante el proceso de nitritación parcial (PN), y a continuación el amonio restante y el nitrito generado se convierten en N2 mediante el proceso anammox, sin necesidad de oxígeno ni materia orgánica. El proceso BNR se ha aplicado al tratamiento de aguas con altas cargas de nitrógeno y temperaturas cálidas, pero nunca se ha implementado en el tratamiento de aguas residuales urbanas (bajas cargas y temperaturas). Recientemente, la investigación se ha centrado en el desarrollo del proceso BNR en un único reactor. Sin embargo, muchos de los estudios publicados mostraron el fallo del proceso PN en la operación a largo plazo al tratar agua urbana, e incluso aquellos sistemas con una operación estable alcanzaron bajas velocidades de eliminación de nitrógeno. En esta tesis se propuso la utilización de un sistema en dos etapas como alternativa para una mejor implementación del proceso BNR en la línea principal de aguas de una EDAR urbana. Así, el principal objetivo fue demostrar la estabilidad de los dos procesos implicados, PN y anammox, en dos reactores independientes tratando un agua residual urbana. En primer lugar se operó en continuo un reactor airlift con biomasa granular tratando un influente sintético que simulaba el efluente de la etapa A-Stage. Se trabajó a bajas temperaturas (hasta los 10 °C) y no solo se consiguió una operación estable a largo plazo sino que se obtuvieron altas velocidades de nitrificación y un efluente adecuado para un reactor anammox contiguo. Además, se determinaron las emisiones de N2O producidas en el reactor y se realizó un estudio del efecto de la temperatura sobre éstas. En segundo lugar se operó en continuo un reactor UASB (Upflow Anaerobic Sludge Blanket) realizando el proceso anammox a largo plazo. Por una parte, se presentó el reactor UASB como una buena alternativa para realizar el proceso anammox en la línea principal de aguas de la depuradora. Además se realizó un estudio exhaustivo del efecto de la velocidad ascensional en el reactor y del efecto de la baja temperatura en la actividad anammox. Por otra parte, el reactor UASB anammox no sólo mostró una operación estable a largo plazo tratando un agua residual urbana real, sino que también se alcanzaron altas velocidades de eliminación de nitrógeno a una temperatura de 11 °C. Conjuntamente, se realizó un estudio detallado de la biomasa desarrollada en ambos reactores desde los puntos de vista microbiológico, cinético y físico-químico, con el objetivo de relacionar estas características con la operación.

Download or read book Anaerobic Digestion Model No.1 (ADM1) written by IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes and published by IWA Publishing. This book was released on 2002-02-01 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Book Synopsis Applications of Activated Sludge Models by : Damir Brdjanovic
Download or read book Applications of Activated Sludge Models written by Damir Brdjanovic and published by IWA Publishing. This book was released on 2015-02-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1982 the International Association on Water Pollution Research and Control (IAWPRC), as it was then called, established a Task Group on Mathematical Modelling for Design and Operation of Activated Sludge Processes. The aim of the Task Group was to create a common platform that could be used for the future development of models for COD and N removal with a minimum of complexity. As the collaborative result of the work of several modelling groups, the Activated Sludge Model No. 1 (ASM1) was published in 1987, exactly 25 years ago. The ASM1 can be considered as the reference model, since this model triggered the general acceptance of wastewater treatment modelling, first in the research community and later on also in practice. ASM1 has become a reference for many scientific and practical projects, and has been implemented (in some cases with modifications) in most of the commercial software available for modelling and simulation of plants for N removal. The models have grown more complex over the years, from ASM1, including N removal processes, to ASM2 (and its variations) including P removal processes, and ASM3 that corrects the deficiencies of ASM1 and is based on a metabolic approach to modelling. So far, ASM1 is the most widely applied. Applications of Activated Sludge Models has been prepared in celebration of 25 years of ASM1 and in tribute to the activated sludge modelling pioneer, the late Professor G.v.R. Marrais. It consists of a dozen of practical applications for ASM models to model development, plant optimization, extension, upgrade, retrofit and troubleshooting, carried out by the members of the Delft modelling group over the last two decades.

Book excerpt: This book focuses on the application of various dyes in the dyeing process and treatment of dyeing wastewater. Chapter One deals with the chemistry and application of reactive dyes, which are the most widely used dyes for the coloration of cellulosic and allied textile fibres. Chapters Two and Three introduce photochromic dyes. Chapter Two gives a general description and Chapter Three describes the chemistry of crown ether styryl dyes in detail. Chapters Four and Five discuss indigo, the oldest known natural blue dye. Chapter Four systematically describes indigo formation in plants and application in textile coloration. Chapter Five discusses the mechanisms of a non-conversional process of indigo reduction. Chapter Six also concerns natural dyes and describes dye extraction from mangrove bark and its application in fabric dyeing. Chapter Seven summarises various kinds of macromolecular auxiliaries for salt-free dyeing auxiliaries and discusses their physiochemical properties and advantages/disadvantages. Chapter Eight aims to investigate the spinning technology of the sheath/core nylon/PET composite filament, to survey the elution characteristics of the fabrics, and to analyse their physical properties. Chapters Nine-Thirteen all discuss the treatment of dyeing wastewater, one of the biggest contributors to water pollution. They concern the different technologies applied in the treatment of dyeing wastewater, including adsorption, electrochemical techniques, coagulation/flocculation, biological treatments, and membrane bioreactors. From these contents, readers can get a good understanding on the current advances and developing trends of treatment technologies for dyeing wastewater.

Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

This book was released on 2017-06-15 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
