Abstract
The treatment of textile industrial wastewater using advanced oxidation process is studied by this work in decolourization of Disperse Red 17. The oxidized materials used were hydrogen peroxide (H2O2) (in the range of 17, 51, 102 and 170 mg/L) and ferrous ions (Fe2+) (in the range of 22.5, 56, 94 and 130 mg/L). A 100 mg/L of Disperse Red 17 dye was used. The reaction was performed in the presence of UV radiation (20 and 40 watts) and without radiation. The study included the effects of peroxide and ferrous concentrations in addition of study of reaction time, mixing rate on the efficiency of contaminants removal, alongwith other conditions, like temperature and pH were considered on their ideal cases for each process. The results show maximum removal efficiency (95.7%) was observed at concentration of 170 mg/L of hydrogen peroxide with agitation speed of 300 rpm in absence of UV radiation whereas maximum removal of 98% using ferrous ions and ultraviolet rays of 40 watts, at time of 60 min and agitation speed of 200 rpm was observed.
