ABSTRACT
The results of the study focused on the impact of membrane on the performance of the integrated system photocatalysis/nanofiltration applied to remove mycoestrogens from water are discussed in the paper. The results were compared with ones obtained during single step photocatalysis and nanofiltration processes. The subject of the study were simulated waters containing difference concentration of humic acids to which mycoestrogens were added to the concentration level 500 μg/dm3. It was shown, that the application of integrated system improved the efficiency of mycoestrogens removal in comparison with single step photocatalysis process. In case of nanofiltration, the efficiency of the treatment was comparable in both, integrated and single nanofiltration processes regardless of the membrane type applied. However, it was found that investigated membranes differ in the affinity to fouling and removal rate of inorganic compounds, what should be considered during water treatment technology development.
