TREATMENT OF TEXTILE WASTE-WATER BY FENTONS REAGENT

Treatment of textile wastewaters from a dyeing and finishing mill by F enton's reagent is investigated. The experimental results are assessed in terms of COD and color (turbidity) reductions to determine the tre atment efficiency of the Fenton's process. Operating variables, such a s the pH, amounts of H2O2 and FeSO4, time of Fenton's treatment and am ounts of polyaluminum chloride (PAC) and polymer, are explored to dete rmine their respective effects on the efficiency of the Fenton's oxida tion of the textile wastewater. Optimum operating range for each of th ose variables are experimen-tally obtained. The operating ranges of th ose were found to be different from those of dye waste-water containin g only single dye component. The treatment of Fenton's reagent was fou nd to be rather effective with an efficiency of COD removal of up to 8 0%.
