Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Download or read book Nitrogen Cycling in Coastal Marine Environments written by T. Henry Blackburn and published by . This book was released on 1988-03-21 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen discharge to the coastal environment has been increasing, posing the threat of accelerated eutrofication. Considerable research has been conducted in recent years to examine the impact of the nitrogen loading in coastal ecosystems. Based on proceedings from a SCOPE symposium held at the University of Aarhus in July of 1985, this volume covers a variety of up-to-date developments in research on nitrogen cycling in coastal marine environments. Topics include the role of nitrogen in algal productivity, regeneration of nutrients in the water column and the sediments, and the flow of nitrogen in coastal ecosystems.

Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

Download or read book Pollution et impact d eaux de ruissellement de chauss es written by Michel Legret and published by . This book was released on 2001 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: De 1996 à 2000, le thème de recherche sur la " pollution et l'impact d'eaux de ruissellement de chaussées " a couvert un ensemble de travaux concernant la caractérisation des eaux de ruissellement pluvial sur les chaussées autoroutières et urbaines ainsi que l'impact des infrastructures sur la qualité des sols et des hydrosystèmes. L'objectif de ce thème est de fournir des données nouvelles permettant d'aider à la gestion des eaux pluviales afin de réduire la pollution et l'impact sur les milieux naturels. Les travaux de recherche du thème ont été subdivisés en trois sujets : - le premier sujet se rapporte à l'étude de la pollution des eaux et sols liée au ruissellement sur les chaussées en rase campagne, et concerne notamment l'évaluation de l'origine et des flux de polluants dus au trafic routier ainsi que les mécanismes de dispersion de ces polluants dans l'environnement ; - le deuxième sujet concerne l'évaluation de l'impact des chaussées poreuses urbaines sur la qualité des eaux de ruissellement et du sol, en particulier à travers le suivi du fonctionnement de chaussées à structure réservoir et de l'étude du phénomène de colmatage de ces structures ; - enfin, le troisième sujet s'intéresse à l'approche biologique de l'impact des rejets d'eaux de ruissellement de chaussées sur les hydrosystèmes, en particulier par la mise en œuvre d'une nouvelle méthode d'évaluation de l'impact basée sur la mesure de l'activité d'un bio-indicateur particulier, le périphyton.
