Alternative Uses for Sewage Sludge


Book Description

The treatment and disposal of sewage sludge is an expensive and environmentally sensitive problem that is growing worldwide. Sludge production is increasing whilst previously accepted methods for disposal are coming under pressure or even being phased out altogether so there is now an urgency to find cost-effective and innovative solutions that appease environmental and public pressures. The purpose of the conference recorded in these proceedings was to review the range of alternative disposal/recycling options for sewage sludge. The alternative uses considered are in land reclamation, forestry, compost and soil production, landfill, incineration, and energy and resource recovery. The papers presented include recent research findings and technological developments, as well as operational implementation of schemes, showing that beneficial re-use of sludge can be entirely compatible with a cost-effective and environmentally sensitive approach to sludge disposal.




Wastewater Sludge Processing


Book Description

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.







Sludge Treatment and Disposal


Book Description

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







Biosolids Treatment Processes


Book Description

The past thirty years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for ”zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the above three questions. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of en- ronmental engineering, and has accounted in large measure for the establi- ment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.




Sludge Reduction Technologies in Wastewater Treatment Plants


Book Description

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.




Wastewater Treatment Engineering


Book Description

This book provides useful information about bioremediation, phytoremediation, and mycoremediation of wastewater and some aspects of the chemical wastewater treatment processes, including ion exchange, neutralization, adsorption, and disinfection. Additionally, this book elucidates and illustrates the wastewater treatment plants in terms of plant sizing, plant layout, plant design, and plant location. Cutting-edge topics include wet air oxidation of aqueous wastes, biodegradation of nitroaromatic compounds, biological treatment of sanitary landfill leachate, bacterial strains for the bioremediation of olive mill wastewater, gelation of arabinoxylans from maize wastewater, and modeling wastewater evolution.







Food Bioconversion


Book Description

Food Bioconversion, Volume Two in the Handbook of Food Bioengineering series is an interdisciplinary resource of fundamental information on waste recovery and biomaterials under certain environmental conditions. The book provides information on how living organisms can be used to transform waste into compounds that can be used in food, and how specialized living cells in plants, animals and water can convert the most polluting agents into useful non-toxic products in a sustainable way. This great reference on the bioconversion of industrial waste is ideal in a time when food resources are limited and entire communities starve. - Presents extraction techniques of biological properties to enhance food's functionality, i.e. functional foods or nutraceuticals - Provides detailed information on waste material recovery issues - Compares different techniques to help advance research and develop new applications - Includes research solutions of different biological treatments to produce foods with antibiotic properties, i.e. probiotics - Explores how bioconversion technologies are essential for research outcomes to increase high quality food production
