Residual organic matter (ROM) removal is an important issue in wastewater reclamation. The performance of photocatalyst/membrane hybrid systems on the removal of ROM from secondary effluents under various conditions was investigated. The variation of TOC and UV254 were examined to evaluate ROM removal, while the degree of membrane fouling was also assessed monitoring transmembrane pressure (TMP) in a constant-flux mode. With an increment of TiO2 concentration, the TOC and UV254 removal efficiency became significant, while TMP increased due to fouling by TiO2 deposition. Significant TOC reduction occurred due to adsorption, but an increase was observed at the initial stage of UV illumination. When wastewater was prefiltered with different pore sizes, significant UV254 and TOC removals were also achieved. |
