This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Los lodos de depuradora son el principal subproducto de las plantas de tratamiento de aguas residuales en todo el mundo. Se estima que debido al crecimiento de la industrialización y de la urbanización, la necesidad de tratar las aguas residuales va a ser cada vez mayor y, en consecuencia, también aumentará la cantidad de lodos de depuradora producidos en las estaciones depuradoras de aguas residuales (EDAR). Los procesos habituales de gestión final de este subproducto incluyen el depósito en vertedero, la incineración y su uso en la agricultura. Sin embargo, debido a que se trata de un residuo rico en metales pesados y patógenos, su gestión se está convirtiendo en uno de los grandes problemas asociados al tratamiento de las aguas residuales, al ser cada día la normativa medioambiental más estricta. Por lo tanto, es necesario buscar de manera urgente alternativas más respetuosas con el medio ambiente y que permitan valorizar este residuo. En este trabajo se propone una vía de valorización dentro del concepto de economía circular que consiste en aprovechar los lodos de depuradora como materia prima de bajo coste para su transformación en productos de alto valor añadido como son los materiales carbonosos porosos con propiedades adsorbentes...

Book excerpt: Resumen: Los lodos provenientes de plantas de tratamientos de aguas residuales suelen poseer grandes concentraciones de materia orgánica que se puede aprovechar en la recuperación de suelos, para lo anterior resulta indispensable una previa estabilización del lodo, tarea llevada a cabo por Agroavícola San Marino una empresa dedicada a la genética avícola que incursiona en el proceso de manufactura de aves y que busca desarrollar todas sus actividades con los más altos niveles de calidad y una búsqueda permanente por la disminución de su impacto ambiental. Buscando cumplir con los objetivos planteados para este proyecto, se realizó una caracterización fisicoquímica y otra microbiológica, los resultados obtenidos fueron comparados con lo establecido en el Decreto 1287 de 2014. Dicho proceso sirvió para determinar el cumplimiento de los requerimientos estipulados en esta norma y plantear una metodología encaminada a corregir aquellos parámetros que en la actualidad no permiten clasificar el lodo objeto de estudio como una sustancia apta para insumo en la fabricación de abonos.
Book Synopsis Gestión de los fangos EDAR mediante la adición de óxido cálcico by : Rebeca Fenoy Baena
Download or read book Gestión de los fangos EDAR mediante la adición de óxido cálcico written by Rebeca Fenoy Baena and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: En este proyecto se realiza un estudio teórico del tratamiento físico químico a los fangos de estaciones depuradoras de aguas residuales mediante la adición de óxido cálcico. De forma que se compara y analiza esta alternativa de gestión de tratamiento previo de los fangos de depuradora para su posterior valorización y/o utilización del producto final obtenido en diferentes ámbitos. Todo ello se realiza para el soporte en el trabajo de tesis de Ricardo José Granados en el desarrollo y ensayo de validación de la planta piloto de tratamiento de fangos de depuradora con óxido cálcico. Dicho Proyecto está vinculado a la tarea 6b del proyecto SOSTAQUA, desarrollado dentro del Programa CENIT, promovido dentro del Centro de Desarrollo Tecnológico Industrial (CDTI). Los objetivos planteados son el estudio de este tratamiento frente a las otras vías de gestión más utilizadas hoy en día como el tratamiento orgánico (compostaje), el secado térmico de los fangos o la digestión aeróbica y anaeróbica entre otros. De forma que se define y analiza el proceso de estudio con la tecnología desarrollada para este tratamiento realizando un análisis teórico del proceso, una descripción de la tecnología utilizada, una evaluación de la viabilidad y una definición de sus aplicaciones posteriores. Después de realizar un estudio de los diferentes tratamiento previos de los fangos y de las diferentes alternativas de aplicación se define y describe la instalación necesaria para el tratamiento de los lodos con óxido cálcico, se analiza el proceso de estabilización de los fangos que tiene lugar en la planta realizando un balance de masas y energías y se realiza la evaluación de impacto ambiental del proceso. Los resultados obtenidos según los valores fijados para el estudio tales como la cantidad de lodos que van a ser tratados, las características de estos lodos, etc. Son la obtención de un producto seco, homogéneo e inertizado viable para su valorización mediante la incorporación en la fabricación de cemento o de materiales de construcción o mediante la disposición del producto obtenido en vertederos de clase II. El producto obtenido en el proceso de estudio tiene una reducción de humedad del 65 % en masa respecto de los fangos de entrada al proceso y además pierde un 65% aproximadamente del peso total de los productos de entrada en el proceso. Esto es gracias a las reacciones que tienen lugar de hidrólisis del CaO y de la degradación de la materia orgánica, las cuales son exotérmicas de forma que la energía que liberan permite la evaporación del agua contenida en los fangos y hace que no sea necesario la aportación de energía extra para la realización del tratamiento.

Book Synopsis Anaerobic Digestion Model No.1 (ADM1) by : IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes
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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.
