| dc.description.abstract | Textile industry is one of the industries that uses a lot of water during the manufacturing process and also releases a lot of effluents containing synthetic colors into the environment, causing health and environmental concerns. Textile companies use reactive blue 19 dye which is regarded major health risks due to its anthraquinone nature. The principal aim of this study is to remove reactive blue 19 dye with Fenton reagents. The main factors of experimental runs of this study are Fenton reagents (H2O2 and ferrous ion Fe 2+ ) and pH of solutions. Currently, the wastewater treatment methods of Bahir Dar textile Share Company are physical, chemical and biological methods for the removal of dyes from wastewater by focusing on aerobic biological processes followed by chemical coagulation. However, these treatment methods have not been effective in treating organic pollutants from textile wastewater due to the complicated aromatic structure and low biodegradability natures. Hence, to solve this environmental problem, this study investigates the potential use of Fenton advanced oxidation treatment methods for the removal of reactive blue 19 dye wastes from textile wastewater. Fenton reagent is a reaction between hydrogen peroxide (H2O2) and ferrous ion (Fe 2+ ) in acidic media to produce hydroxyl radical, and be a strong oxidant capable of oxidizing various organic compounds. This process is oxidation process for the removal of color and chemical oxygen demand (COD) from textile wastewater containing dyes. Batch experiments were carried out in order to study the effect of various dose of Fenton reagents for removal efficiency of reactive blue 19 dye. The maximum removal efficiencies were 90.8%and 94.8% for color and COD respectively under the dosages of 20 mg/l of Fe 2+ , 100mg/l of H2O2 and pH of 3.5. Fenton process is able to remove reactive blue 19 dye from textile wastewater with different dose of Fenton reagents in acidic media.
