A New Method for the Deposition of Metallic Silver on Porous Ceramic Water Filters

Figure 3

Average log change of E. coli, log(C/C0), versus pore volumes of flow after an one-min pulse injection of E. coli to ceramic filters manufactured using the silver nanoparticle method and the silver nitrate application method. Error bars show one standard error above and below the mean. For the silver nitrate application method, the mass of added silver was five times (5x) or ten times (10x) the mass of silver applied to the ceramic filter fabricated using the silver nanoparticle method. Samples were taken at the same time for each disk and converted to pore volume. Since pore volumes varied minimally (3%) between disks, samples at the same time were averaged.
