Produktbeschreibung

A practice-oriented analysis of water treatment systems using low-cost, low-maintenance technologies and sustainable water resources In Sustainable Water Systems, expert water resources researcher Miklas Scholz delivers a practice-oriented resource that comprehensively covers the design, operation, and maintenance of traditional and novel wetland systems used in water resource management. The book offers a performance analysis of existing infrastructure in constructed wetlands, soil infiltration systems, ditches, dry ponds, and silt traps in both developed and developing countries. Sustainable Water Systems addresses economic and environmental challenges, including flood retention and its incorporation into sustainable water supply systems. Readers will also find: * A thorough introduction to low-cost alternatives to resource-intensive water processing plants * Comprehensive explorations of effective water technologies that work well in less developed and rural regions without access to reliable water treatment * Modelling of wetland systems and how to design them for optimal performance * Practical discussions of industrial wastewater treatment and modelling * Complete treatments of sustainable flood retention basins, including integrated constructed wetlands Perfect for researchers, engineers, and other professionals working in the field of water resource management, Sustainable Water Systems will also benefit anyone interested in water supply engineering and wastewater treatment.
