Advanced water treatment processes, including nanofiltration (NF) membranes, granular activated carbon (GAC), and ozone process, were evaluated in terms of removal efficiencies of personal care products (PCP). Four different PCP compounds that included DEET, galaxolide, tonalide, and musk ketone, were used to evaluate their removal efficiency by selected advanced water treatment processes. Two different NF membranes, RF and NE40, were studied to investigate PCP removal mechanisms. PCP compounds which have higher molecular weight and higher K_ow were more effectively removed by NF membranes. Two different GAC, SCL-100 and F-400, completely removed all of tested PCPs. Compared to other processes, ozone provided relatively low removal efficiencies of PCPs. Includes 8 references, tables, figures.
