Book Description
Cette thèse porte sur la mise en œuvre et le démarrage d'un réacteur à lit turbulé inverse avec des particules d'ExtendospheresÔ pour le traitement anaérobie d'un effluent agro-alimentaire. Une étude hydrodynamique a permis de caractériser les écoulements et le macro-mélange en présence de ce support de petite taille (147æm) et de faible densité (0,7). L'hypothèse d'un pseudo-fluide homogène liquide-solide dont la viscosité apparente dépend de la quantité de solide illustre bien le comportement des phases lors de l'injection du gaz pour la fluidisation. Une étude biologique a montré que le contact initial entre cellules et support entraîne une adaptation physiologique des microorganismes à la présence de solide après une inhibition temporaire de la méthanisation. Le rendement en méthane s'est avéré un paramètre de suivi intéressant de la formation et du détachement du biofilm. Un faible temps de séjour hydraulique lors du démarrage a permis de réduire la phase de latence lors de la colonisation du support. Un fonctionnement continu robuste du réacteur a été obtenu grâce à un contrôle de l'alimentation par le pH. Elle a aussi permis d'étudier l'influence de la fluidisation par le gaz sur le taux d'attrition du biofilm. La vitesse du gaz est apparue comme un paramètre de contrôle actif de la proportion de cellules, de la densité et de la résistance du biofilm.

Book Description
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 Description
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.
