RESUMEN
This study was conducted to investigate the efficiency of Fenton's reagent (hydrogen peroxide + Ferrousion (Fe+2)) in removing the color and COD (Chemical Oxygen Demand) of a reactive dye wastewater. The textile dyeing wastewater was treated in a continuous reactor. The results showed that the best pH value for Fenton's treatment process was 4 and the optimal contact time for slow mixing was 20 minutes. The average percent color and COD removal efficiency was about 90% and 65%, respectively. Characteristics of wastewater such as contamination with oil makes decolorization, the removal of red color, difficult.
