| Tartalmi kivonat: | Oily pollutions can be efficiently eliminated from waters by membrane filtration and by advanced oxidation processes as well, and the advantageous of the combination of these methods have also been reported [1,2]. Humic pollutions naturally can appear in oily contaminated waters (either in surface- or ground waters [3]), which may affect both ozonation and membrane filtration due to their amphiphilic- and antioxidant properties. In the present study the advantages of the combination of pre-ozonation with membrane filtration was investigated in case of humic-acid containing oil in water emulsions. Fluxes, resistances, membrane foulings and purification efficiencies were investigated in case of different durations of pre-ozonation, and applying different water matrixes (low- and high salt concentrations). In summary, a short (2 minute) pre-ozonation (~ 20 mg/L1 absorbed ozone) increases the available flux and reduces the membrane resistance also in the presence of humic acid. |
