Bimetallic V2O5-TiO2 catalyst coupled with ceramic membranes for the facile oxidation of micropollutants |
| 초록 |
A residue of micropollutants in drinking water cause health problmes. However, conventional water treatment couldn’t mineralize it. To enhance the removal efficiency, ozone with ceramic membrane system is proposed. Moreover, the heterogeneous catalysts are introduced in the ozonation processes due to the increased production of hydroxyl radicals. In this study, we conducted the hybrid ozone-ceramic membrane process with V2O5-TiO2 for the enhancement of removal of micropollutants. After V2O5 was successfully coated on the membrane through filtration-coating method, the catalytic oxidation effect was evaluated in the presence of ozone. The hybrid system was conducted in the dead-end cell, 2 mg/L of dissolved ozone concentration, and 1 mg/L of 4 selected compounds. As a result, the hybrid system with V2O5-TiO2 catalyst depicted higher removal rate than without catalyst due to the catalytic reaction between ozone and V2O5 nanoparticles incorporated in the ceramic membrane. |
