Title: Integrating Microbial Systems into the Engineered Water Cycle to Improve Sustainability and Promote Public Health (seminar announcement attached)
Conventional drinking water treatment goes to great lengths to eliminate microorganisms from drinking water, but despite these efforts tap water still contains millions of bacterial cells per liter. Instead of trying to eliminate microorganisms from drinking water systems, we can integrate microbial systems into the engineered water cycle to improve sustainability and promote public health. Using bench-scale systems, we have shown that biologically-active carbon filters can remove several harmful contaminants (perchlorate, nitrate, hexavalent chromium) from drinking water sources. However, we found that chloramine disinfection of biofilter effluents in a full-scale water treatment plant enriched for opportunistic, pathogenic bacteria. Results of this research have the potential to promote biofiltration for drinking water treatment but underscore the need for more research on disinfection efficacy of mixed microbial communities in biologically-treated water.
