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
Processing of Solid-Liquid Suspensions is a collection of articles from several industrialists and academicians who are active in fundamental and applied research relating to handling and processing of particles in liquids. This collection of papers deals with the processes of interaction of particles with each other, with the surrounding liquid and process equipment, whereby knowledge of the mechanism of these interactions can be a sound basis for improving the design of the process equipment and create an optimum environment for the formation and processing of the particulate. The above notion is explained through analysis of the role of turbulent aggregation and breakup of particles in the formation of many solid products from aqueous solutions. This book also analyzes particle size and particulate crystals, whether as final products or as intermediates during processing. In the purification of proteins, two essential units of operation are used; precipitation and solid-liquid separation are analyzed, where theoretical considerations are reviewed. This text also discusses the application of model suspensions in the design of aerobic fermenters in practical industrial uses. High concentration of suspension preparations and solid suspension in liquid flourized beds or in stirred vessels are explained in more detail as to how these affect certain industries. This selection finally presents the progress made in developing design and methods needed by industry. Researchers, chemists, and scientists in industry, as well as advanced students with interests in formation and processing of stable suspensions and in advanced process engineering courses will find this textbook a valuable aid.

Book Description
A Frequency Dictionary of French is an invaluable tool for all learners of French, providing a list of the 5000 most frequently used words in the language. Based on a 23-million-word corpus of French which includes written and spoken material both from France and overseas, this dictionary provides the user with detailed information for each of the 5000 entries, including English equivalents, a sample sentence, its English translation, usage statistics, and an indication of register variation. Users can access the top 5000 words either through the main frequency listing or through an alphabetical index. Throughout the frequency listing there are thematically-organized lists of the top words from a variety of key topics such as sports, weather, clothing, and family terms. An engaging and highly useful resource, the Frequency Dictionary of French will enable students of all levels to get the most out of their study of French vocabulary. Former CD content is now available to access at www.routledge.com/9780415775311 as support material. Designed for use by corpus and computational linguists it provides the full text in a format that researchers can process and turn into suitable lists for their own research work. Deryle Lonsdale is Associate Professor in the Linguistics and English Language Department at Brigham Young University (Provo, Utah). Yvon Le Bras is Associate Professor of French and Department Chair of the French and Italian Department at Brigham Young University (Provo, Utah).

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.

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
Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.
