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. Authors: Linda Strande,Eawag, Switzerland, Mariska

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.
