| Abstract |
D-0 bleaching wastewater from E. globulus Kraft pulping industry was treated by Fenton and photo-Fenton processes. The aim was to optimize the operational conditions for adsorbable organic halides (AOX) removal, namely oxidant concentration, [H2O2], catalyst concentration, [Fe2+], and treatment time, using the central composite experimental design (CCED) tool. Temperature and pH were set at 60 degrees C and 2, respectively, which are similar to the natural values of the D-0 bleaching wastewater. Both processes showed potential to remove AOX from D-0 with 177 - 178 mM H2O2 and 10 min reaction time. Maximum AOX removal was 85 % for the Fenton process with 8.5 mM Fe2+, and 95 % for the photo-Fenton process with 2.0 mM Fe2+ and UV irradiance 142 W.m(-2). For both methods, the only statistically significant variable (p=0.05) was the concentration of oxidant, [H2O2]. (C) 2019 Published by Elsevier Ltd. |
