FIG. 3. (A) Measured and fitted breakthrough curves and (B) retention profiles for Deinococcus radiodurans at 100% saturation. Fitted curves were obtained using the attachment model, the Langmuirian model, and the 2 site model. In Fig. 3A, 127 min is equal to 1 pore volume. C/C0 = relative effluent concentration, where C0 is the influent concentration of bacteria; Nt, number of bacteria recovered in the sand; Ni, number in a unit volume of the input bacterial suspension.
