The definitive guide to alternative water sources and wastewater solutions This timely volume discusses alternative water sources and waste disposal methods that are appropriate when traditional means and methods do not exist or are inadequate. Alternative Water Sources and Wastewater Management presents a variety of innovative concepts that are being researched, developed, and implemented worldwide. Featuring detailed illustrations, an eight-page color insert, current examples, statistics, and calculations, this book provides the vital information needed to address the rapidly increasing global demand for clean water. Coverage includes: Water cycle water sources Springs Air conditioning condensate recovery Dew harvesting Fog harvesting Glacier water harvesting Rainwater catchment Solar distillation of water Graywater systems Water quality maintenance Ground water recharge Aquatic plants as waste management system Biological fi lters and constructed wetlands Blackwater recycling systems Septic system design Latrines and privies Composting toilets Net zero water
"This manual contains overview information on treatment technologies, installation practices, and past performance."--Introduction.
In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.
Decentralized Wastewater Management presents a comprehensive approach to the design of both conventional and innovative systems for the treatment and disposal of wastewater or the reuse of treaded effluent. Smaller treatment plants, which are the concern of most new engineers, are the primary focus of this important book.
Adopting a multi-disciplinary approach, Decentralised Sanitation and Reuse places public sanitation in a global context and provides a definitive discussion of current state-of-the-art sanitation technologies. It shows how these technologies can be implemented to integrate domestic waste and wastewater treatment in order to maximize resource recycling in domestic practice. Decentralised Sanitation and Reuse presents technical solutions for on-site collection and transport of concentrated waste streams, and focuses on the compromise between reliability and minimal water wastage. A whole range of available sustainable technologies, both low and high-tech, to treat concentrated (black water) and diluted (grey water) streams are addressed in detail from the fundamental scientific and engineering points of view. Sociological, economic and, particularly, environmental and public health aspects are essential issues within this book. The necessity of new infrastructure implementation and the resulting challenges for a good number of economic branches are illustrated with examples from architecture and town planning. Decentralised Sanitation and Reuse will be an invaluable resource for a wide academic and professional readership active in the fields of environmental protection and public sanitation. Contents The DESAR concept for environmental protection Waste and wastewater characteristics and its collection on the site Technological aspects of DESAR Environmental and public health aspects of DESAR Sociological and economic aspects of DESAR Architectural and urbanistic aspects of DESAR
A-Z guide to soil/plant/microbe-based wastewatertreatment Engineers and planners eager to benefit from the costefficiencies and convenience of land treatment of waste will find practical guidelines in this comprehensive manual. It covers soil hydraulics, vegetation selection, site selection, field investigations, preapplication treatment and storage, and transmission and distribution of wastewater. You're introduced to: Design procedures and appropriate uses for each of the three land treatment processes: soils, plants, and microbiological agents Special attributes of food processing wastewater, with 6 case studies The use of biosolids produced by mechanical treatment systems as crop nutrients Options for preapplication treatment, including ponds and constructed wetlands Much more
The scope of this comprehensive new edition of Handbook of Biological Wastewater Treatment ranges from the design of the activated sludge system, final settlers, auxiliary units (sludge thickeners and digesters) to pre-treatment units such as primary settlers and UASB reactors. The core of the book deals with the optimized design of biological and chemical nutrient removal. The book presents the state-of-the-art theory concerning the various aspects of the activated sludge system and develops procedures for optimized cost-based design and operation. It offers a truly integrated cost-based design method that can be easily implemented in spreadsheets and adapted to the particular needs of the user. Handbook of Biological Wastewater Treatment: Second Edition incorporates valuable new material that improves the instructive qualities of the first edition. The book has a new structure that makes the material more readily understandable and the numerous additional examples clarify the text. On the website www.wastewaterhandbook.com three free excel design spreadsheets for different configurations (secondary treatment with and without primary settling and nitrogen removal) can be downloaded to get the reader started with their own design projects. New sections have been added throughout: to explain the difference between true and apparent yield while the section on the F/M ratio, and especially the reasons not to use it, has been expanded; to demonstrate the effect of the oxygen recycle to the anoxic zones on both the denitrification capacity and the concept of available nitrate is explained in more detail. the latest developments on the causes and solution to sludge bulking and scum formation to show the rapid developments of innovative nitrogen removal and sludge separation problems the anaerobic pre-treatment section is completely rewritten based on the experiences obtained from an extensive review of large full-scale UASB based sewage treatment plants a new section on industrial anaerobic wastewater treatment three new appendices have been added. These deal with the calibration of the denitrification model, empirical design guidelines for final settler design (STORA/STOWA and ATV) and with the potential for development of denitrification in the final settler. A new chapter on moving bed biofilm reactors Handbook of Biological Wastewater Treatment: Second Edition is written for post graduate students and engineers in consulting firms and environmental protection agencies. It is an invaluable resource for everybody working in the field of wastewater treatment. Lecturer support material is available when adopted for university courses. This includes course material for the first 7 modules in the form of PDF printouts and an exercise file with questions and answers and a symbol list. Authors: Prof. dr. ir. A.C. van Haandel, Federal University of Campina Grande - Brazil and Ir. J.G.M. van der Lubbe, Biothane Systems International - Veolia, The Netherlands
Affordable and effective domestic wastewater treatment is a critical issue in public health and disease prevention around the world, particularly so in developing countries which often lack the financial and technical resources necessary for proper treatment facilities. This practical guide provides state-of-the-art coverage of methods for domestic wastewater treatment and provides a foundation to the practical design of wastewater treatment and re-use systems. The emphasis is on low-cost, low-energy, low-maintenance, high-performance 'natural' systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture, for fish and aquatic vegetable pond fertilization. Modern design methodologies, with worked design examples, are described for waste stabilization ponds, wastewater storage and treatment reservoirs; constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches. This book is essential reading for engineers, academics and upper-level and graduate students in engineering, wastewater management and public health, and others interested in sustainable and cost-effective technologies for reducing wastewater-related diseases and environmental damage.
