Biotechnologies for Water Treatment

Abstract

The Story in brief water and wastewater utilities face major changes in their treatment systems as a result of recent environmental regulations. Not only do these new rules specify reduction requirements for contaminats not previously regulated they also target the by-products of chlorination, which has been the basic disinfection technique in this country since the early days of municipal water treatment. As a result, EPRI has been working with the American Water Works Association Research Foundation and the water Environment Research Foundation to support the development of advanced treatment alternatives and improve energy efficiency at treatment facilities The work has identified a number of innovative, electrically based treatment technologies that provide the additional capabilities required, promote higher efficiency in treatment processes, and serve electric utilities' demand-side management objectives.
