Optimizing Filter Operation in an Ozone-Biofiltration Plant to Reduce Selection for Opportunistic Pathogens in Drinking Water Production

The incidence of waterborne disease outbreaks attributed to opportunistic human pathogens that are not regulated by the EPA appears to be increasing compared to infections caused by traditional fecal-borne pathogens. This research will focus on reduced selection for opportunistic bacterial pathogens during drinking water treatment with a particular emphasis on non-tuberculous mycobacteria (NTM). Specifically, the research team hopes to optimize filter backwashing procedures to reduce selection for disinfectant-resistant, opportunistic pathogens, while maintaining or improving conventional filtration performance parameters.
