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.

Sludge treatment and disposal is the sixth volume in the series Biological wastewater treatment. The book covers in a clear and didactic way the sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are also fully described. The Biological Wastewater Treatment series is based on the book Biological Wastewater Treatment in Warm Climate Regions and on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other books in the Biological Wastewater Treatment series: Volume 1: Wastewater characteristics, treatment and disposal Volume 2: Basic principles of wastewater treatment Volume 3: Waste stabilisation ponds Volume 4: Anaerobic reactors Volume 5: Activated sludge and aerobic biofilm reactors Volume 6: Sludge treatment and disposal

Plus d'un milliard de personnes dans les zones urbaines et periurbaines d'Afrique, d'Asie et d'Amerique latine sont desservies par des dispositifs d'assainissement a la parcelle. La gestion des boues extraites de ces dispositifs, les " boues de vidange ", a ete jusqu'a present grandement negligee. Les ressources financieres sont souvent insuffisantes et les dispositifs d'assainissement a la parcelle ont tendance a etre consideres comme des solutions temporaires, dan l'attente de la mise en place de reseaux d'egouts. Cependant , force est de constater que l'assainissement a la parcelle est la pour durer, soit en tant que solution autonome permanente, soit en association avec des systemes egouts-station. La gestion adequate des boues de vidange issues des dispositifs d'assainissement des menages est un imperatif pour la protection de Ia sante humaine et de l'environnement. Cet ouvrage est le premier a etre consacre a la gestion des boues de vidange. II rassemble l'etat actuel des connaissances de ce domaine qui evolue rapidement, et propose une approche integree qui lie les composantes technologiques, organisationnelles et de planification. II aborde la planification et l'organisation de l'ensemble de la filiere de gestion des boues de vidange depuis la collecte et l'evacuation des boues jusqu'aux solutions de traitement et a l'utilisation finale ou la mise en depot des boues traitees. En plus de fournir des elements fondamentaux sur le traitement et une description des technologies existantes, l'ouvrage presente en detail les aspects operationnels, institutionnels et financiers. II propose egalement une methode de planification d'un projet de gestion des boues de vidange a l'echelle d'une ville avec l'ensemble des parties prenantes.
