Available in PDF, EPUB and Kindle. Book excerpt: Thèse de doctorat en Chimie et microbiologie de l'eau. En France, le traitement des eaux résiduaires abouti à une production annuelle de 865 000 tonnes de boues d'épuration (M.S.) en majeure partie éliminées par incinération ou par valorisation agricole. La contamination microbiologique des boues brutes est systématique, du fait même de leur nature fécale. Par ailleurs, ces boues à forte teneur en matière organique sont très souvent le siège de fermentations, à l'origine de nuisances olfactives. Elles doivent donc subir, avant d'être valorisées en agriculture, un ou plusieurs traitements de stabilisation, visant essentiellement à réduire leur pouvoir fermentescible. Ces traitements de stabilisation sont généralement défavorables à la survie des micro-organismes et certains d'entre eux entraînent une telle inactivation des pathogènes qu'ils sont qualifiés de traitements hygiénisants. Ainsi, la réglementation française a-t-elle introduit la notion de boues hygiénisées, qui doivent contenir moins de 8 salmonelles, moins de 3 oeufs d'heminthes viables et moins de 3 Enterovirus (NPPUC) par 10 grammes de matière sèche. Les boues stabilisées, ou hygiénisées, sont épandues à l'état liquide, pâteux ou solide, après une période de stockage pouvant aller jsuqu'à 9 mois. Au cours de ces différentes étapes de stabilisation et de stockage, les micro-organismes entériques sont soumis à une inactivation. Néanmoins, les quantités de virus, bactéries et oeufs de parasites intestinaux épandues sur les sols peuvent constituer un risque de contamination des hommes ou des animaux, qui dépend notamment de leur survie dans les sols et leur dose minimale infectante. L'obejctif du travail a été d'étudier la contamination microbiologique des boues d'épuration urbaines, et, plus particulièrement le devenir de certains micro-organismes pendant le stockage des boues et à la suite de 2 traitements susceptibles d'être considérés comme hygiénisants, à savoir le chaulage et le compostage. L'étude a porté sur 3 micro-organismes pathogènes (Enterovirus, salmonelles et oeufs de nématodes viables) et parallèlement sur 2 indicateurs bactériens de contamination (E. coli et entérocoques) et 3 indicateurs potentiels de contamination virale ( coliphages somatiques, bactériophages à ARN F spécifiques et bactériophages de B. fragilis).[...]

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 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 Sustainable Sludge Management written by R. D. Tyagi and published by Amer Society of Civil Engineers. This book was released on 2009 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stricter regulations in many countries are increasing interest in sludge management processes which promote sustainability. Engineers and scientists are looking for viable options for resource management through the creation of value added-products from wastewater sludge. The ASCE's Technical Committee on Hazardous, Toxic, and Radioactive Waste Management identified the need to collect and present the latest information on recent trends in the bioconversion of sludge to value-added products like biopesticides, biosurfactants, enzymes, bioplastics, and biofertilizers/bioflocculants. The committee envisioned an easy-to-read book to serve as a reference for practicing professionals and as a textbook in undergraduate or graduate courses. Sustainable Sludge Management: Production of Value-Added Products offers an examination of wastewater sludge characteristics; a road to sustainability by converting sludge into value-added products; and detailed information on the various types of value-added products being created from sludge. This book will be valuable to undergraduate and graduate students in environmental engineering, educators, researchers, practicing engineers and scientists.
