Fig. 3. (A) log values of E. coli cell numbers in filtrates after filtering through MWCNTs coated filters with three different levels of MWCNTs loading. The MWCNT loadings were 1.5, 3, or 4.5 mg MWCNTs. The surface coatings on the filters were 0.15 mg CDots or SWCNTs. (B) The effects of CDots and SWCNTs loading on the bacterial removal efficiency showing by log reductions in E. coli cell numbers after filtration using the coated filters loading with three different levels of CDots and SWCNTs (0.1 mg, 0.15 mg, and 0.2 mg).
