| description | The objective of this study is to evaluate the performance of photocatalysis/hydrogen
peroxide/metal membrane system. Metal membrane for the separation of TiO2 particles was used in
an experiment and nominal pore size is 0.5 μm. Hydrogen peroxide was tested as oxidants. The
removal efficiency of CODCr and color for initial hydrogen peroxide concentration increases rapidly
with an increase in the hydrogen peroxide concentration up to 50 mg/L. The removal efficiency of
of CODCr and color for 50 mg/L of initial hydrogen peroxide concentration was about 95 % and
98 %, respectively. However, the addition of hydrogen peroxide over 50 mg/L inhibits the system
efficiency. The addition of hydrogen peroxide in UV/TiO2 system enhanced removal efficiency of
CODCr and color compared to no addition of hydrogen peroxide. This may be ascribed to capture
the electrons ejected from TiO2 and to produce OH radicals. The application of metal membrane in
UV/ TiO2/H2O2 system enhanced removal efficiency of CODCr and color due to the adsorption of
metal membrane surface as well as the production of OH radical. In application of metal membrane
with nominal pore size 0.5 μm, TiO2 particles were effectively separated from the treated water by
metal membrane rejection. Photocatalytic metal membrane was much smaller resistance than these
of humic acid, TiO2 and humic acid/ TiO2 due to humic acid degradation of photocatalytic reaction. |
