Sewage Treatment in Hot Climates by David Duncan Mara Pdf
In warmer climates, sewage loses its content of dissolved oxygen more rapidly, causing it to become "stale" or "septic", necessitating the use of waste stabilization ponds. Waste stabilization ponds utilize environmentally-aware technology in treating the wastewater of communities in hot climates. This book covers waste stabilization ponds in detail, and examines wastewater management and treatment today.
Constructed Wetlands for Wastewater Treatment in Hot and Arid Climates by Alexandros Stefanakis Pdf
This edited book presents the first collection of case studies and research projects on the sustainable technology of constructed wetlands for wastewater management under hot and arid climates. It is the first such work that summarizes in a single reference the current international experiences and knowledge on the implementation of this nature-based solution under these diverse and often harsh climatic conditions. It covers the relevant gap in the fragmented and limited literature by providing integrated information and documentation on the feasibility of this green technology. The book presents the treatment efficiency of constructed wetland facilities and the research output from 29 different countries across South America, Africa, Asia and Oceania, while it covers various applications such as domestic and municipal wastewater, various industrial effluents and municipal sludge. Many examples and case studies further demonstrate the potential of this technology to contribute to better address the issues of water scarcity and limited fresh water resources through circular management of treated effluents e.g. reuse in irrigation. It also discusses the various challenges and technical aspects that should be considered in such climates, along with the environmental, financial and social benefits of this technology. This work is a useful handbook and guide for professional engineers, practitioners, academics, researchers, students, and water authorities who wish to get a better understanding and first-hand information on the potential of constructed wetlands for cost-effective and sustainable wastewater management in countries with hot and arid climates.
Biological Wastewater Treatment in Warm Climate Regions by Marcos Von Sperling,Carlos Augustos de Lemos Chernicharo Pdf
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.
Wastewater Treatment in Dry Climates (desert Or Desert with Some Rain) by Mark J. Hammer Pdf
This publication details the most appropriate unit processes for wastewater treatment in a dry climate, which is defined as a desert or a desert with some rain. The knowledge and technology revealed in this book comes from years of extensive research in Saudi Arabian wastewater treatment plants. The research reveals dramatic effects on treatment processes in hot, dry climates resulting in high wastewater temperatures. Evaluations of these treatment plants show that the primary cause of operational problems results from the application of inappropriate design standards, or those intended for plants located in temperate climates. An invaluable reference and research tool, this publication also incorporates problems and solutions so that it can be used as a college textbook. Learn about design considerations, wastewater treatment, sludge processing, and methods of treating wastewater for disposal or reuse in dry climates. --

Domestic Wastewater Treatment in Developing Countries by Duncan Mara Pdf
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.
