Abstract
The Photocatalytic activity was investigated with the increase of flow rate in a $UV/TiO_2$ packed-bed system. The rate of phenol degradation over $UV/TiO_2$ (dia. = 5 mm) was increased up to 300 mL/min and reached a plateau beyond 400 mL/min. The bead photocatalysts did not exhibit a distinct difference of the phenol degradation rate irrespective of corrosion rates of glass beads and $TiO_2$ coating amounts. Degussa P25 exhibited a higher photocatalytic activity in comparison to other $TiO_2$ sols(Ishihara & N). The performance(activity and durability) of $UV/TiO_2$ packed-bed system can be enhanced by the use of $TiO_2$-coated glass beads instead of granular types that is easily attrited by the shearing force of flowing fluids.
