Abstract
The document discusses water treatment technologies and associated cost for removing turbidity, Giardia, viruses and bacteria from public drinking water supplies. The document discusses the technologies which can be used to comply with the EPA's proposed surface water treatment requirements plus the total coliform maximum contaminants levels (MCLs). (An extensive source reference is provided.) Technologies discussed include conventional treatment (coagulation, flocculation, sedimentation, and filtration), direct filtration, diatomaceous earth filtration, slow-sand filtration, and package plants. Disinfection methods discussed include chlorine, chlorine dioxide, chloramines and ozone. Alternative filtration and disinfection technologies are also discussed.
