Book Description
Biofilms -- Science and Technology covers the main topics of biofilm formation and activity, from basic science to applied aspects in engineering and medicine. The book presents a masterly discussion of microbial adhesion, the metabolism of microorganisms in biofilms, modelling of mass transfer and biological reaction within biofilms, as well as the behaviour of these microbial communities in industry (waste water treatment, heat exchanger biofouling, membranes, food processing) and in medicine (teeth, implants, prosthetic devices). Laboratory techniques and industrial monitoring methods are also presented. The book is directed at readers at the postgraduate level and is organised as a textbook, containing 11 chapters, a glossary, and a detailed subject index.

Book Description
Water Pollution Control in Asia documents the proceedings of the Second IAWPRC Asian Conference on Water Pollution Control, held in Bangkok, Thailand, 9-11 November 1988. The conference brings together the various factors that must be considered when investigating the development of water supply and control of sewage disposal systems, especially for small villages or towns and large communities in Asia which are situated too far from a piped system of water supply, thus requiring its own sources treatment and sewage disposal. The contributions made by researchers at the conference are organized into seven parts. Part 1 examines the various aspects of water quality management. The papers in Part 2 deal with the analysis and cleanup of river, lake, and marine pollution. Part 3 discusses the treatment of human waste while Part 4 is devoted to industrial waste treatment approaches. Part 5 focuses on water treatment methods. Part 6 contains studies on water reuse and groundwater contamination. The papers in Part 7 cover various topics such as wastewater management in developing countries and the treatment of phenolic wastewater using rotating biological contactors.

Book Description
Cette étude concerne l'incinération des boues résiduaires humides dans un réacteur à lit fluidisé chauffé par appoint de gaz naturel. Leur combustion est un ensemble de mécanismes qui comprend le séchage, la pyrolise et la combustion des volatiles. L'étude parmétrique sur le séchage de pastilles de boues en lit fluidié à flottation, validée par un modèle cinétique, montre que la cinétique de séchage peut être représentée par le déplacement d'un front humide de la surface de pastille vers son centre. Lors de la combustion des boues, des interactions entre l'avancement de la combustion et la formation et disparition de CO, NOx et N2O ont été mis en évidences. Une majorité du cadmium, du plomb et du cuivre se volatilisent alors que le zinc, le nickel et le chrome sont adsorbés par les particules de sable. Les émissions de CO, NOx et N2O et la répartition des métaux lourds sont fortement dépendantes de la température du lit et du débit d'alimentation des boues.

Book Description
The central theme of the book is the flow of information from experimental approaches in biofilm research to simulation and modeling of complex wastewater systems. Probably the greatest challenge in wastewater research lies in using the methods and the results obtained in one scientific discipline to design intelligent experiments in other disciplines, and eventually to improve the knowledge base the practitioner needs to run wastewater treatment plants. The purpose of Biofilms in Wastewater Treatment is to provide engineers with the knowledge needed to apply the new insights gained by researchers. The authors provide an authoritative insight into the function of biofilms on a technical and on a lab-scale, cover some of the exciting new basic microbiological and wastewater engineering research involving molecular biology techniques and microscopy, and discuss recent attempts to predict the development of biofilms. This book is divided into 3 sections: Modeling and Simulation; Architecture, Population Structure and Function; and From Fundamentals to Practical Application, which all start with a scientific question. Individual chapters attempt to answer the question and present different angles of looking at problems. In addition there is an extensive glossary to familiarize the non-expert with unfamiliar terminology used by microbiologists and computational scientists.

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
More than 10 years after the "First European Symposium on Organic Micropollutants in the Aquatic Environment", the "Sixth Symposium" was held in Lisbon (Portugal) from 22 to 24 May 1990. The Symposium was organised within the framework of the Concerted Action COST 641 * which is included in the Fourth R&D Programme on the Environment of the Commission of the European Communities expiring at the end of 1990. After restructuring the Concerted Action in 1984, particular attention has been devoted to fate and transformation of organic micropollutants in the aquatic environment. Therefore, a major aim of the Symposium was to review current studies and progress in these areas, besides more general aspects related to analytical methodologies and behaviour of pollutants during water treatment processes. This volume contains the plenary papers presented in the following sessions at the Symposium: - Multidisciplinary studies - Partitioning of organic micropollutants in the aquatic environment - Novel analytical techniques in environmental chemistry - Monitoring micropollutant - Degradation of organic micropollutants during field conditions - Reclamation of polluted ground water - Chemical and photochemical oxidation - Future of environmental chemistry. In addition, extended versions of posters are included, covering the four topics which are dealt within the four Working Parties forming the structure of the Concerted Action: 1. Analytical methodologies 2. Transport and distribution 3. Transformation reactions 4. Water treatment. We believe that the Proceedings give a good overview of current activities in these fields of research in Europe.
