Wastewater Sludge

Reap the benefits of sludge The processing of wastewater sludge for use or disposal has been a continuing challenge for municipal agencies. Yet, whensludge is properly processed, the resulting nutrient-rich product--biosolids--can be a valuable resource for agriculture and other uses. Wastewater Sludge Processing brings together a wide body of knowledge from the field to examine how to effectively process sludge to reap its benefits, yet protect public health. Presented in a format useful as both a reference for practicing environmental engineers and a textbook for graduatestudents, this book discusses unit operations used for processing sludge and the available methods for final disposition of the processed product. Topics discussed include sludge quantities and characteristics, thickening and dewatering, aerobicand anaerobic digestion, alkaline stabilization, composting, thermal drying and incineration, energy consumption, and the beneficial use of biosolids. COMPREHENSIVE IN ITS COVERAGE, THE TEXT: * Describes new and emerging technologies as well as international methods * Compares different types of sludge processing methods * Explains both municipal and industrial treatment technologies Written by authors with decades of experience in the field, Wastewater Sludge Processing is an invaluable tool for anyone planning, designing, and implementing municipal wastewater sludge management projects.

New Edition now available - click hereIt is well recognized everywhere that management of sludge derived from wastewater treatment is one of the most critical environmental issues, due to the very fast increase in sludge production as a result of sewerage extension, new installations and upgrading of existing facilities. Within this general picture, sludge is produced under different technical, economic and social contexts, thus requiring different approaches. This report is intended to give an overview of the sludge field in different parts of the world by summarising: current wastewater and sludge treatment provision; current and anticipated legislation; current research horizons; anticipated evolution of management approaches; and prospects for use of innovative and / or simple technologies. The report has been prepared for the Water21 Market Briefing Series in collaboration with the International Water Association's Specialist Group on Sludge Management. It is based on contributions from: Western Europe (Johannes Mueller); Eastern Europe (Pavel Jenicek); North America (Steve Dentel); Latin America and the Caribbean (Jose Barrios); East Asia (Nagaharu Okuno); South Asia and China (Duu-Jong Lee); Africa (Heidi Snyman); and Australasia (David Dixon and Terry Anderson). There is also an introduction and overview section (Ludovico Spinosa).

Sludge Reduction Technologies in Wastewater Treatment Plants is a review of the sludge reduction techniques integrated in wastewater treatment plants with detailed chapters on the most promising and most widespread techniques. The aim of the book is to update the international community on the current status of knowledge and techniques in the field of sludge reduction. It will provide a comprehensive understanding of the following issues in sludge reduction: principles of sludge reduction techniques; process configurations; potential performance; advantages and drawbacks; economics and energy consumption. This book will be essential reading for managers and technical staff of wastewater treatment plants as well as graduate students and post-graduate specialists.

Intended for advanced students and practitioners of wastewater engineering, this text explains the theory and quantitative rationale for treating wastewater and industrial sludges, with public safety and efficiency in mind. It offers important information on various practices for safe and legal sludge disposal.

Sewage sludge is the product resulting from wastewater treatment plants and aquaculture systems. It is an abundant waste biomass, as its production keeps increasing due to population growth, particularly in developing countries and intensified wastewater treatment plants in the developed world due to industrialisation. Effective management and handling of sewage sludge in an environmentally friendly way has become a matter of increasing importance globally, due to the potential health risks on the environment. Importantly, sewage sludge contains large amounts of organic components and nutrients; hence, resource recovery from such an abundant biomass is necessary. This comprehensive book presents an assessment into the impact of sewage sludge on the environment and provides the various treatment options for converting the sludge into useful resources. Biochemical (or biological) and thermochemical (or thermal) methods of sewage sludge treatment are covered. Through contributions from experts in diverse fields, this book has been organised to suit a variety of readers, including professionals and students who are interested in sewage sludge treatment as well as resource recovery from sewage sludge by using different and innovative technologies.

Sludge Treatment and Disposal is the sixth volume in the series Biological Wastewater Treatment. The book covers in a clear and informative way the sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are also fully described. About the series: The series is based on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other titles in the series are: Volume 1: Waste Stabilisation Ponds; Volume 2: Basic Principles of Wastewater Treatment; Volume 3: Waste Stabilization Ponds; Volume 4: Anaerobic Reactors; Volume 5: Activated Sludge and Aerobic Biofilm Reactors

Following a successful first edition published in 2007, the follow-up 2011 edition of Wastewater Sludge - A Global Overview of the Current Status and Future Prospects will present an updated and expanded perspective on developments in relation to wastewater sludge around the world. Sludge arising from wastewater treatment represents a serious environmental issue, requiring technological and management solutions to ensure it is processed in a safe and economically efficient manner. Extension of sewers, the construction of new wastewater treatment facilities and the upgrading of existing wastewater plants means the amount of sludge to be handled continues to increase. Alongside this, aspects relating to energy consumption and sustainable operation need to be considered. Within this general picture, sludge is generated in different technical, economic and social contexts around the world, demanding that different approaches need to be taken. The 2011 edition of this report provides a strategic overview of the wastewater sludge market around the world, based on regional and country contributions. These look at the current situation in terms of sludge generation, legislation, technology applied and management management approaches. These will then look at anticipated developments over the short / medium term, including expected developments in terms of legislation and the technology and management solutions to be implemented. These will be complemented by longer term perspectives also. The report has been prepared for the Market Briefing Series of the International Water Association's magazine Water21, with input from IWA's network of wastewater sludge experts around the world. Contributions in the 2011 edition include Western Europe, Portugal, Italy, Belgium, Eastern Europe, Turkey, USA, Canada, Latin America / Caribbean, Colombia, Brazil, East Asia, Korea, Malaysia, South Asia, China, Africa, and Australasia.
