Fundamental study on development of photocatalytic reactor with TiO2-coated fluoropolymer beads

Abstract

This study examined flow rate dependence of treatment efficiency in TiO2 photocatalystreactor. The photoreactor made of TiO2 immobilized fluoropolymer beads which has the same refractive index of water. The methylene blue aqueous solution was circulated and decomposed to evaluate the performance of the reactor. As a result, when changing the flow rate per reactor from 0.0125 L / min to 0.42 L / min, the pseudo first order reaction constant increased by 1.67 times. Also, the Reynolds number in the reactor was calculated and the relation with the pseudo first order reaction constant was examined.
