Resumen : El propósito fundamental de la actual investigación fue realizar un proceso experimental de tratamiento de aguas residuales procedentes de la industria textil para eliminación de colorantes mediante fotocatálisis con dióxido de titanio; para lo cual se tuvieron en cuenta las características químicas y físicas del agua residual de la industria textil antes del tratamiento, para luego determinar la efectividad de diferentes concentraciones de dióxido de titanio en procesos de tratamientos de las muestras expuestas a diferentes fuentes de radiación mediante el análisis de la incidencia de las variables estudiadas...
Descripción : The fundamental purpose of the current research was to carry out an experimental process of wastewater treatment from the textile industry for elimination of dyes by photocatalysis with titanium dioxide; for which the chemical and physical characteristics of the wastewater of the textile industry before the treatment were taken into account, to then determine the effectiveness of different concentrations of titanium dioxide in treatment processes of the samples exposed to different sources of radiation by means of the Analysis of the incidence of the variables studied. For the research in question, the mixed approach was applied, being the study of historical, descriptive and experimental type, where the 2k complete factorial design was chosen based on the combination of the variables: chemical oxygen demand (COD), color, turbidity, pH and temperature; resulting in a successful COD removal and color reduction using UV light, for a sample volume of 1000 ml, with a residence time of 6 hours, at 150 rpm and with a pH of 3, as optimum conditions obtained. In the photocatalysis, the effect of the pH was determinant for the degradation of the color, being this one inversely proportional to the response variable, with an optimal value of three; however, it could be noted that the final temperature of the solution did not show significant change. In general, it is concluded that heterogeneous photocatalysis (TiO2) is a viable treatment to treat contaminated water coming from the dyeing process of textile industries and with which high percentages of color decrease and chemical oxygen demand are reached, which is conditioned to a greater or lesser extent both by the concentration of the catalyst (TiO2) and the source of radiation used in its treatment.
