Book Description
Cette étude a été consacrée à l'analyse du processus d'agglomération du sulfate de potassium et de l'alumine dans un milieu liquide turbulent. La turbidité constitue une technique tout à fait adaptée à la caractérisation de l'agglomération dont les effets sont ressentis essentiellement au niveau de la distribution granulométrique de la phase dispersée. Elle permet de quantifier et d'interpréter l'effet des différents paramètres qui interviennent au cours du développement du processus: - paramètres hydrodynamiques : la cinétique d'agglomération est conditionnée par le mécanisme de rencontre des particules, lui-même dépendant des conditions hydrodynamiques; la morphologie des agglomérats peut témoigner de cette dépendance ; - paramètres physico-chimiques : lorsque les particule se rencontrent les interactions interviennent et assurent ou non la cohésion de l'amas formé. Il est nécessaire, enfin, de tenir compte de l’agglomération lorsque le comportement d’un système diphasique est influencé par l’évolution de la distribution granulométrique de la phase dispersé : c’est le cas dans la plupart des procédés de cristallisation.

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
Agro-industrial wastes are end-products emerging after industrial processing operations and also from their treatment and disposal e.g. solid fruit wastes and sludge. The agro-industrial wastes are often present in multiphase and comprise multicomponent. Nevertheless, these wastes are a goldmine as they possess valuable organic matter which can be diverted towards high value products ranging from polymers to antibiotics to platform chemicals. There have been plenty of books published on bioenergy, enzymes and organic acids, among others. However, this emerging field of biochemical has not yet been covered so far which is an important entity of the biorefinery model from waste biomass and needs to be understood from fundamental, applied as well as commercial perspective which has been laid out in this book.

Book Description
This book represents a first considered attempt to study the factors that conditioned industrial chemistry for war in 1914-18. Taking a comparative perspective, it reflects on the experience of France, Germany, Austria, Russia, Britain, Italy and Russia, and points to significant similarities and differences. It looks at changing patterns in the organisation of industry, and at the emerging symbiosis between science, industry and the military.
