Domestic Wastewater Treatment in Developing Countries

<p>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.</p> <p>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. </p> <p>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.</p> What is Domestic Wastewater and Why Treat It? * Excreta-related Diseases * Essential Microbiology and Biology * Effluent Quality * BOD Removal Kinetics * Domestic Wastewater Treatment Options * Domestic Wastewater Flows and Loads * Preliminary Treatment * Waste Stabilization Ponds (WSP) * Anaerobic Ponds * Facultative Ponds * Maturation Ponds * Physical Design of WSP * Operation and Maintenance of WSP * Monitoring and Evaluation of WSP * Wastewater Storage and Treatment Reservoirs * Constructed Wetlands * Upflow Anaerobic Sludge Blanket Reactors * Biofiltration * Simple Activated Sludge Variants * Waste Re-use in Agriculture * Wastewater Re-use in Aquaculture * References
