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.

This book is devoted to sewage sludge, its sustainable management, and its use and implications on soil fertility and crop production. The book traces the main chemical and biological properties of sewage sludge, and covers topics such as sewage sludge biostabilization and detoxification, biological and thermochemical treatment technologies, emerging nutrient recovery technologies, the role of microorganisms in sewage sludge management, and the sustainable use of sewage sludge as fertilizer in agriculture. The book offers a valuable asset for researchers, scholars and policymakers alike.

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

This book summarises current knowledge and experience of the properties of construction materials made from sewage sludge derivatives as well as assessing the potential savings and hazards of using sewage sludge as a construction material.

Comprehensive reference examining activated sludge technologies in industrial wastewater treatment, combining a theoretical framework with practical methodologies Application of Sewage Sludge in Industrial Wastewater Treatment provides a roadmap to the methodologies for the treatment of industrial wastewaters from several major sectors integrating theory and practice, highlighting the importance of sewage sludge technologies in industrial wastewater treatment to clean up the environment from pollution caused by human activities, and assessing the applications of several existing activated sludge techniques and introduces new emerging technologies. All discussion within the text is based on a solid theoretical background. Application of Sewage Sludge in Industrial Wastewater Treatment covers key topics such as: Issues related to activated sludge treatment, such as biodegradability-based characterization, modeling, assessment of stoichiometric, and kinetic parameters and design Issues related to industrial pollution control, such as in-plant control, effect of pretreatment, and more Recently increasing quantity and complexity of toxic effluents, which can be bio remediable for plants and suitable microbes, whether natural or customized for specific purposes Ecological, profitable, and natural solutions designed to eliminate heavy metals, radionuclides, xenobiotic compounds, organic waste, pesticides, and more This reference provides an essential, one-of-a-kind, integrated approach for environmental microbiologists, biochemical engineers, environmental engineers, effluent treatment plant operators, and biologists and chemists at wastewater treatment plants.

Varying degrees of environmental impact by sewage sludge disposals alternatives, present challenges for waste management practice and policy. Many regulating bodies throughout the world are implementing measures which actively promote environmentally sound and economically viable routes to convert this waste into a valuable resource. These provide opportunities, but at the same time, given the nature of the material and obstacles that may exist, require that responsible and proven practices are followed. This book presents the proceedings of an International Symposium organised by the Concrete Technology Unit, University of Dundee, which brings together some of the worlds leading experts in the field of sewage sludge recycling.
