Download or read book Dise o construcci n y validaci n de un sistema de reciclado de agua de un lavabo para su uso en sanitarios written by Ester Gonzáez Quero and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La realización del presente proyecto de final de carrera viene motivada por la necesidad de diseñar un lavabo capaz de reciclar la gran cantidad de agua que se utiliza en las actividades cotidianas de higiene (lavado de cara, manos, dientes, afeitado...) y que se realizan en cualquier hogar. La aplicación de principios de sostenibilidad en la gestión y optimización de los recursos hídricos es una obligación y necesidad en todos los ámbitos. En este sentido, el desarrollo de mecanismos eficaces, capaces de reducir el consumo de agua de cara a contrarrestar la inminente reducción de los recursos hídricos ha sido uno de los principales objetivos para la realización de este proyecto. Los sistemas de saneamiento comúnmente utilizados para el tratamiento de las aguas residuales (sistema habitual de alcantarillado y estaciones depuradoras) no tienen en cuenta la naturaleza de las aguas, no obstante no todas las aguas tienen la misma calidad. En términos generales se distingue entre aguas grises y aguas negras. Las aguas grises son específicamente las que provienen del cuarto de baño, lavaderos... y que no arrastran organismos que puedan contener enfermedades. En cambio las aguas negras, por lo contrario, provienen principalmente de los retretes y contienen grandes cantidades de materia orgánica, nitrógeno y celulosa. La separación de las aguas negras de las aguas residuales domésticas (aguas grises) se considera como un paso muy importante hacia un planteamiento sostenible del uso del agua. Así mismo, las aguas grises utilizadas apropiadamente constituyen una fuente de gran valor y su reutilización supone un alargamiento de su ciclo de vida añadiendo valor a su uso. En el desarrollo del proyecto se intentará dar solución a algunas de las preguntas que nos aparecen cuando desaprovechamos el agua del lavabo. De la necesidad de la sociedad por conseguir un ahorro de agua, han surgido muchas ideas de cómo reutilizar, aprovechar y no malgastar este recurso natural tan importante. Este proyecto contempla una idea que posiblemente todos nos hemos planteado alguna vez, pero que nadie se ha propuesto llevar a cabo. En resumen, en el siguiente proyecto se dará explicación de los conceptos e ideas que se han utilizado para diseñar un inodoro capaz de reciclar el agua del lavabo para la descarga de las cisternas. Se presentará la normativa vigente y las diferentes tecnologías existentes, se expondrá el diseño conceptual y se realizará una evaluación económica del coste y la evaluación de su implicación ambiental.

Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.
Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. 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.

Download or read book Cradle to Cradle written by William McDonough and published by North Point Press. This book was released on 2010-03-01 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: A manifesto for a radically different philosophy and practice of manufacture and environmentalism "Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. But as this provocative, visionary book argues, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world? In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are). Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, William McDonough and Michael Braungart make an exciting and viable case for change.

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.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Boundaries written by Christine E. Gudorf and published by Georgetown University Press. This book was released on 2010-04-15 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this expanded and revised edition of a fresh and original case-study textbook on environmental ethics, Christine Gudorf and James Huchingson continue to explore the line that separates the current state of the environment from what it should be in the future. Boundaries begins with a lucid overview of the field, highlighting the key developments and theories in the environmental movement. Specific cases offer a rich and diverse range of situations from around the globe, from saving the forests of Java and the use of pesticides in developing countries to restoring degraded ecosystems in Nebraska. With an emphasis on the concrete circumstances of particular localities, the studies continue to focus on the dilemmas and struggles of individuals and communities who face daunting decisions with serious consequences. This second edition features extensive updates and revisions, along with four new cases: one on water privatization, one on governmental efforts to mitigate global climate change, and two on the obstacles that teachers of environmental ethics encounter in the classroom. Boundaries also includes an appendix for teachers that describes how to use the cases in the classroom.
