Effects Of Phosphate On The Transport Of Escherichia Coli In Saturated Quartz Sand, Nan Chen
Theses and Dissertations
Bacterial deposition and survival in porous media is a crucial phenomenon in various environmental processes including bioremediation, water treatment, and pathogen contamination. The fate of bacteria in porous media may be greatly influenced by ionic strength and phosphate. Although phosphate is widespread in the natural environment, the influence of phosphate on the transport of three strains of ESCHERICHIA COLI O157:H7 cells in the groundwater system remains unknown.
Experiments were performed in saturated sand packed columns with and without phosphate to examine the transport of bacteria, deposition rate coefficient, interaction energy between bacteria and sand, and bacteria surface charge.
