Removing organic contaminants in water
A new report by the American Water Works Associations Research Foundation (AwwaRF) provides a comprehensive and systematic investigation of 18 treatment processes used by U.S. water utilities to remove endocrine-disrupting contaminants (EDCs) and pharmaceuticals and personal-care products (know as PPCPs). Removal of EDCs and Pharmaceuticals in Drinking and Reuse Treatment Processes describes analytical techniques developed by researchers at the Southern Nevada Water Authority and Arizona State University to assess the removal efficiency of the treatments and presents results from bench- and pilot-scale testing.
"Utilities that wish to remove the vast majority of microcontaminants should consider advanced processes such as ozonation, advanced oxidation processes, granular activated carbon, reverse osmosis, or tight nanofiltration," the report says. Currently accessible to AwwaRF members, the report will be available to the public in early 2008.
