Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1996 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les normes plus restrictives de rejets après traitement des eaux résiduaires urbaines, ainsi que l'obligation faite aux petites localités d'être équipées (d'ici 2005) de leur propre station d'épuration, entraînent le développement de nouveaux systèmes de dépollution. Le couplage de techniques membranaires au procédé de traitement biologique par boues activées apporte une solution à ces contraintes. L'étape de la clarification par décantation y est supprimée, et la possibilité d'opérer avec des boues âgées et fortement concentrées permet de réduire le volume des ouvrages. Le procédé de traitement avec les membranes directement immergées dans la boue activée représente la 2ème génération de ces systèmes de couplage, il succède au procédé dit à boucle externe et il apporte une simplification de mise en oeuvre et une réduction des coûts énergétiques. L'étude présente les conditions de fonctionnement du procédé de boues activées à membranes immergées (BAMI) tant sous l'aspect de l'épuration biologique que sous l'aspect des performances hydrauliques. Elle permet de définir des conditions opératoires permettant d'obtenir une élimination très poussée de la DCO et de l'azote, ainsi que des flux de perméat stables. La qualité bactériologique de l'eau traitée est satisfaisante. Le dispositif est insensible au phénomène de foisonnement, élimine les risques de perte des boues vers le milieu récepteur et par rapport à un traitement conventionnel, la production de boues en excès est réduite.

Book excerpt: Ce travail traite de l'épuration des eaux usées urbaines en s'appuyant sur le procédé à boues activées, qui est la technique la plus utilisée dans les pays occidentaux. Néanmoins le cas des pays en voie de développement est évoqué à la fin du rapport.La première partie explique la nécessité d'épurer les eaux usées, dans le but de préserver l'environnement et la ressource en eau potable ; elle aborde aussi les paramètres utilisés pour quantifier la pollution avant et après traitement.Ensuite, le principe du procédé à boues activées est expliqué.Le traitement biologique des eaux usées produit des boues. Ces boues doivent être détruites ou valorisées, ce qui constitue le point noir de l'épuration des eaux usées et soulève de grandes questions. Ces questions sont exposées dans la troisième partie.La dernière partie aborde les traitements d'épuration du futur, principalement les améliorations en cours de mise au point et les améliorations attendues.

Download or read book Activated Sludge Separation Problems written by Valter Tandoi and published by IWA Publishing. This book was released on 2017-09-15 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated Sludge Separation Problems: Theory, Control Measures, Practical Experiences, Second Edition, describes the most common activated sludge separation problems and explains the main reasons for the growth of the different filamentous microorganisms in activated sludge. The book summarizes the identification techniques for important groups of activated sludge microorganisms both based on conventional microscopic analysis and using the biological molecular tools available today (FISH and PCR). This new edition, with 70% new and updated material, also provides explanation of basic activated sludge process principles and of parameters necessary for process control and operation. The theory of secondary clarifies is described to the extent necessary for understanding the construction and operation of secondary clarifiers. The activated sludge reactor and secondary clarifies are treated as one system and the interactions are explained. The wide range of experiences around the world is documented and the methods to avoid the proliferation of these organisms are presented and critically reviewed. Activated Sludge Separation Problems consists of six chapters, presenting up-to-date technical and scientific aspects of these processes. The new edition also features an extended list of literature references for further reading. The book will be a valuable help for students of environmental engineering, wastewater specialists, plant operators and designers of activated sludge plants. It is also useful for specialists in wastewater operation laboratories, especially for those studying activated sludge separation properties.

Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A young writer has his heart set on his aunt's large apartment. With this seemingly simple conceit, the characters of The Planetarium are set in orbit and a galaxy of argument, resentment, and bitterness erupts. Telling the story from various points of view, Sarraute focuses below the surface, on the emotional lives of the characters in a way that surpasses even Virginia Woolf. Always deeply engaging, The Planetarium reveals the deep disparity between the way we see ourselves and the way others see us.
