Based on the fact that many micropollutants such as endocrine disrupting compounds
(EDCs) and pharmaceutically active compounds (PhACs) have a molecular weight of >150
dalton, it is expected that nanofiltration (NF) or reverse osmosis (RO) membranes would control these compounds. In order to relate the physical/chemical
properties of these compounds to membrane properties, and to develop a database which
can be used for the prediction of rejection performance of a membrane for a certain
compound, it is essential to establish an experimental protocol to rationally determine the
rejection rate. In this study, it was shown that the determination of rejection rate is not
straightforward due to adsorption of compounds on membranes, especially when
hydrophobic and electro-statically neutral compounds are examined. The experimental
results demonstrated that a relatively large amount of the feed water needed to be filtered
for saturation. Includes 13 references, tables, figures.
