To address the challenge of high-water consumption, massive wastewater discharge and high risk of pollution in textile industries, different countries have chosen various treatment methods for textile wastewater according to the location and management of the wastewater. textile companies. To address this need, the present study carried out an environmental evaluation of a conventional process implemented in the textile industry in Medellín (Colombia) compared to modifying this process with advanced oxidation techniques based on hydrogen peroxide and ultraviolet radiation. In this sense, a modeling of the two treatment processes was carried out in the GPS-X 7.0.1 software, and the mass and energy balances necessary for the inventory of resources and waste necessary and produced in each process. The environmental impact analysis was carried out by implementing the life cycle analysis using the Gabi software. The results showed how the treatment is improved with the modification of the conventional process with advanced oxidation. However, the environmental impact increases with the integration of hydrogen peroxide and UV radiation, so looking for more efficient or environmentally friendly advanced oxidation alternatives is necessary.
