Over the past twenty years, the knowledge and understanding of wastewater treatment has advanced extensively and moved away from empirically based approaches to a fundamentally-based first principles approach embracing chemistry, microbiology, and physical and bioprocess engineering, often involving experimental laboratory work and techniques. Many of these experimental methods and techniques have matured to the degree that they have been accepted as reliable tools in wastewater treatment research and practice. For sector professionals, especially a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access to advanced level laboratory courses in wastewater treatment is not readily available. In addition, information on innovative experimental methods is scattered across scientific literature and only partially available in the form of textbooks or guidelines. This book seeks to address these deficiencies. It assembles and integrates the innovative experimental methods developed by research groups and practitioners around the world. Experimental Methods in Wastewater Treatment forms part of the internet-based curriculum in wastewater treatment at UNESCO-IHE and, as such, may also be used together with video records of experimental methods performed and narrated by the authors including guidelines on what to do and what not to do. The book is written for undergraduate and postgraduate students, researchers, laboratory staff, plant operators, consultants, and other sector professionals.

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.

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.
