Abstract

A novel photocatalytic filter is developed by depositing a TiO2 (anatase) film on a porous quartz disc. It is found to be compatible with the ultrapure water (UPW) system. SEM micrographs show that the TiO2 film is uniform and the pore size is not lowered. The photocatalyzed oxidation of trace chlorinated hydrocarbons in ultrapure water is investigated. 1,1,1-trichloroethane (1,1,1-TCA), trichloroethylene (TCE) and chloroform are tested as total oxidizable carbon (TOC) model compounds. Significant increase in the overall TOC removal efficiency is observed for all the three chlorinated compounds. Two types of low mercury vapor UV lamps are tested but little difference is observed. A trace amount of ozone is introduced into the ultrapure water stream as an extra oxidant source. The overall TOC removal efficiency is increased but the photocatalytic effect is not enhanced significantly.
