Process Control of Activated Sludge Plants by Microscopic Investigation
ISBN: 9781900222297
eISBN: 9781789060003
Process stability and final effluent quality largely depend upon the composition of the biomass in an activated sludge plant. Operational problems such as bulking and scum formation occur when the wrong micro-organisms are dominating the sludge population. Microscopic sludge investigation is therefore essential for process control and stable plant operation. The manual outlines the theoretical framework, extensively illustrated with full-colour micrographs.
Contents: - Microscopy - Microscopic sludge investigation - Characteristics of activated sludge flocs - Filamentous micro-organisms - Protozoa and metazoa - Conclusions of microscopic sludge investigation - The activated sludge process - Operational problems - Bulking sludge - Scum formation.
Organic Waste Recycling: Technology and Management – Third Edition
ISBN: 9781843391210
eISBN: 9781780402024
This book covers the principles and practices of technologies for the control of pollution originating from organic wastes (e.g. human faeces and urine, wastewater, solid wastes, animal manure and agro-industrial wastes) and the recycling of these organic wastes into valuable products such as fertilizer, biofuels, algal and fish protein and irrigated crops.
Each recycling technology is described with respect to: - Objectives - Benefits and limitations - Environmental requirements - Design criteria of the process - Use of the recycled products - Public health aspects. Organic Waste Recycling includes case studies, examples, exercises and questions. This book is intended as a text or reference book for third or fourth year undergraduate students interested in environmental science, engineering and management, and graduate students working in the environment-related disciplines. It also serves as a reference text for policy makers, planners and professionals working in the environment and sustainable development fields.
Manejo de Lodos Fecales
ISBN: 9781780408019
eISBN: 9781780408026
This book is a Spanish translation of Faecal Sludge Management: Systems Approach for Implementation and Operation.
Más de 1.000 millones de personas en las áreas urbanas y peri-urbanas de África, Asia y América utilizan tecnologías descentralizadas de saneamiento. Hasta ahora se ha descuidado tremendamente el manejo de los lodos fecales producidos por estas tecnologías. Los recursos financieros son frecuentemente insuficientes y estos sistemas descentralizados suelen ser vistos como soluciones temporales, hasta poder implementar sistemas con alcantarillado. Sin embargo, la verdad es que el saneamiento descentralizado está aquí para quedarse, sea como soluciones independientes temporales o permanentes, o en combinación con sistemas basados en el alcantarillado. El manejo adecuado y apropiado de los lodos fecales es primordial para la protección de la salud humana y ambiental. Este es el primer libro dedicado netamente al manejo de lodos fecales. Compila el estado actual de conocimiento en este campo que está evolucionando rápidamente y presenta un enfoque integrado que incluye la tecnología, el manejo y la planificación. Aborda la planificación y organización de toda la cadena de servicios de manejo de lodos fecales, desde su recolección y transporte hasta su tratamiento y uso o disposición final. Además de resumir los fundamentos y tecnologías, el libro también expone los detalles de los aspectos operativos, institucionales y financieros y las pautas para planificar un proyecto para el manejo de lodos fecales con la participación de todos los actores. Editado.
Biological Wastewater Treatment in Warm Climate Regions Volume II
ISBN: 9781843391074
eISBN: 9781780402703
Biological Wastewater Treatment in Warm Climate Regions gives a state-of-the-art presentation of the science and technology of biological wastewater treatment, particularly domestic sewage. The book covers the main treatment processes used worldwide with wastewater treatment in warm climate regions given a particular emphasis where simple, affordable and sustainable solutions are required.
This comprehensive book presents in a clear and informative way the basic principles of biological wastewater treatment, including theory and practice, and covering conception, design and operation. In order to ensure the practical and didactic view of the book, 371 illustrations, 322 summary tables and 117 examples are included. All major wastewater treatment processes are covered by full and interlinked design examples which are built up throughout the book, from the determination of wastewater characteristics, the impact of discharge into rivers and lakes, the design of several wastewater treatment processes and the design of sludge treatment and disposal units. The 55 chapters are divided into 7 parts over two volumes: Volume One: (1) Introduction to wastewater characteristics, treatment and disposal; (2) Basic principles of wastewater treatment; (3) Stabilisation ponds; (4) Anaerobic reactors; Volume Two: (5) Activated sludge; (6) Aerobic biofilm reactors; (7) Sludge treatment and disposal. As well as being an ideal textbook, Biological Wastewater Treatment in Warm Climate Regions is an important reference for practising professionals such as engineers, biologists, chemists and environmental scientists, acting in consulting companies, water authorities and environmental agencies.
