This study addresses the possibility for nanofiltration (NF) membrane processes to serve as analternative to remove low levels of selected antibiotics from surface waters and wastewatersgiven changing water conditions such as pH. Preliminary results from bench-scale cross-flowfiltration tests suggest that antibiotic rejection is highly dependent on membrane pore size as wellas changes in pH due to varying electrostatic interactions between the charged antibiotics and themembrane surface. The extended Nernst-Planck model was applied to further understand thesize-exclusion and electrostatic mechanisms behind the observed experimental data. Includes 19 references, table, figures.
