Description
This study addresses the possibility for nanofiltration (NF) and reverse osmosis (RO) membraneprocesses to serve as an alternative to remove low levels of selected antibiotics from wastewatersand surface waters given changing water conditions such as pH and presence of natural organicmatter (NOM). Preliminary experimental results obtained with a dead-end filtration apparatussuggest that adsorption of antibiotics onto the membrane surface is negligible. However,removal is greatly affected by changes in pH due to changes in electrostatic repulsion betweencharged antibiotics and membrane surfaces. Both the pore diffusion model for NF and thesolution diffusion model for RO will be applied to further understand the mechanisms and trendsbehind the experimental data. Includes 17 references, table, figure.
