Resumen:
The treatment of reject water from a nanofiltration system by photo-oxidation with ultraviolet light and titanium dioxide (TiO2) showed that degradation efficiency of the organic micropollutants (OMPs) varied depending on the reaction time analyzed. Thus, compounds such as diclofenac and ibuprofen exhibited greater than 95 % degradation within the first 15 min, while less than 65 % of naproxen and gemfibrozil was degraded after 15 min of reaction time. Salicylic acid had the lowest degradation efficiency in 15 min (<45 %) of all of the compounds studied. In addition to radical recombination, suspended particles limit potential homogeneous illumination in the reaction system while the presence of organic material causes parallel hydroxyl radical-consuming reactions, which may be responsible for low degradation efficiencies under these conditions. © Springer International Publishing Switzerland 2017.
