Book Synopsis Faecal Sludge Management by : Linda Strande
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.
Book Synopsis How to Design Wastewater Systems for Local Conditions in Developing Countries by : David M. Robbins
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.

Book Synopsis Caractérisation expérimentale et modélisation de l'émission de polluants lors de l'incinération des déchets ménagers by : Thomas Rogaume

This book was released on 2001 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif principal est relatif à l'étude de la formation des polluants et notamment des oxydes d'azote lors de la combustion des déchets ménagers. Un mélange, composé de bois, de carton et de plastiques, représentatif de la fraction combustible des ordures ménagères a été retenu pour la partie expérimentale réalisée dans le but de contribuer à l'amélioration des techniques primaires de réduction des oxydes d'azote lors de l'incinération et de leurs mécanismes de formation. A la suite de l'étude expérimentale, un modèle permettant la simulation du processus chimique de la combustion des ordures ménagères a été développé, mis au point et validé. A l'aide de ce modèle les zones et les intermédiaires réactionnels importants au sein du pilote de combustion ont été définis. Les résultats obtenus sont susceptibles de développements et d'applications industrielles.
Book Synopsis Carbonisation discontinue du bois en four à combustion partielle by : Narendra Shah
Download or read book Carbonisation discontinue du bois en four à combustion partielle written by Narendra Shah and published by . This book was released on 1990 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: La technique de carbonisation en four à combustion partielle dépend, aujoud'hui, des critères de contrôle subjectifs qui sont difficiles â normaliser, exige une surveillance continue et aboutit à un rendement de conversion aléatoire. Cette étude a été conduite dans le but d'améliorer les connaissances sur la carbonisation discontinue en four à combustion partielle. Partant d'une expérimentation sur un four pilote, ces travaux de recherche ont testé les différents capteurs et la validité des informations fournis pour mettre en évidence l'influence des paramètres portants sur les rendements de conversion, sur la qualité de charbon de bois, sur la composition des émissions, sur l'évolution des températures et sur l'évolution de perte de masse. Le suivi de la perte de masse apparaît comme un paramètre intéressant permettant une meilleure gestion du cycle de carbonisation.

This book was released on 2009 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deals with a theoretical study of heat and mass transfer by combined mixed convection, radiation and chemical kinetics in an incinerator of wood carbonization with recovery and incineration of the pyrolysis fumes. A thermochemical model was elaborated to predict the temperatures, molar flows (in particular molar flow responsible for the racing of the incineration reaction) and the concentrations in each zone of the pilot plant. The radiative transfers in the gas phase and soot are modelled by applying the weighted sum of the grey gases model. We applied the finite volume method and the "blocked-off-region" procedure to handle the complex geometries. The equations governing the transfers by combined mixed convection, radiation and the chemical kinetics are solved by the finite volume method, TDMA and the SIMPLE algorithms. We analyzed the shadow effect caused by the baffles, the fumes optical thickness, the Boltzmann number, the conduction-radiation parameter, Reynolds number and the Richardson number. We determined the best configuration of the baffles and shown that the increase in the soot volume fraction causes an increase in radiative heat flux and the presence of soot at a temperature different from that of the fume causes a radiative thermal non equilibrium. The partial pressure ratio of H2O and CO2 does not effect the radiative heat flux on the walls of the incinerator. The heat generated by the incineration of the fumes causes intensification and homogenisation of the transfers in a forced convection mode. The results of the thermochemical model are in qualitative and quantitative good agreement with the experimental results
