Abstract

In this article, the degradation efficiencies of UV/TiO2, UV/H2O2, and UV/O3 processes are compared in the removal of ACID RED 14 which is the most commonly used dye in the textile industry. Results show UV/TiO2 recorded a degradation efficiency of above 90% in 30 minutes (pH=3, [Dye]=40mg/L, [TiO2]=400mg/L), UV/H2O2 degraded 75mg/L of dye (a degradation efficiency of more than 90%) in 160 minutes, and the efficiency of UV/O3 was above 95% in only 15 minutes using an ozone concentration of 0.9gr/h ([Dye]=250mg/L, PH=9). Judging on their high efficiencies, the use of these processes is recommended for the treatment of textile effluents. It may be noted, however, that the two processes of UV/H2O2 and UV/O3 are effective in both dye degradation and COD removal, but UV/O3 is costly and needs especial equipment. UV/TiO2 is not effective in COD removal and requires the post-treatment separation of nano-particles (using a centrifuge or sedimentation process). Thus, the UV/H2O2 process seems to be the easiest and most effective process in the treatment of textile effluent due to its simplicity and effective COD removal in a short time.
