Disinfectants and Disinfection Byproducts (Web-based)
Disinfectant biofilm penetration and its effect on biofilm aerobic activity and viability are still unclear. The use of microelectrodes have contributed to a greater understanding of biological mechanisms in biofilm and sediments. This presentation will provide a summary of EPA's research conducted on disinfectant penetration into biofilm and sediment where the disinfectant concentrations were measured with microelectrodes. Free chlorine and monochloramine penetration will be compared, and the impact of disinfectant penetration on viability of biofilm will be discussed.
