Abstract:

The unconscious use of surface and ground waters and the rapid pollution of water, which is the main source of life for all living creatures as a result of drought due to global warming, pose a serious problem. The rapidly increasing world population and the need for clean water have brought up a global water crisis. The textile industry is one of the largest producers of wastewater in the world. Textile industry wastewater contains high amounts of non-biodegradable organic compounds, high concentrations of dyestuffs, salt, detergent and soap. Therefore, it is of great importance to remove organic pollutants in this wastewater. Since traditional methods are insufficient to remove organic compounds in wastewater, advanced treatment methods are required. Advanced oxidation processes (AOPs) are one of the alternative treatment methods preferred in recent years. In this study, color removal from textile industry wastewater was researched by the heterogeneous Fenton process, which is an advanced oxidation process. The parameters such as catalyst dosage, pH, hydrogen peroxide concentration, temperature, reaction time and mixing speed that effect heterogeneous Fenton processes were investigated. Under optimum experimental conditions, the color removal efficiency was achieved as 87%.
