The appropriateness and the economy of the technology must be an integral part of the selection process. This book emphasizes application of the methods and outlines their design criteria in a simplified manner. The authors discuss in detail process modifications and upgrading of conventional treatment facilities. The first two chapters introduce the water quantity and quality requirements and outline both conventional and advanced water treatment processes. The subsequent six chapters extensively discuss the six unit processes in drinking water treatment.
Emphasis is given to low-cost methods that can be successfully applied in developing countries.
Inc. Describes feasible technologies, operating procedures, management and financing opportunities to alleviate problems faced by small water systems in both developed and developing countries. In addition to widely used traditional technologies, the 74 papers also present promising emerging technologies and nontraditional approaches. Coverage includes disinfection of waterborne pathogens, filtration, pre-engineered treatment systems, analytical monitoring, well remediation, and training programs. The May 1998 symposium was organized by NSF International, the Pan American Health Organization, and the World Health Organization.
