The textile industry is responsible for generating a large amount of a very complex wastewater during its production process. This wastewater contains residual dyes, high concentration of salt, soaps and detergents. Also, dyes used in the process are soluble in water, but not biodegradable and may be toxic for the environment. The present work proposes using advanced chemical oxidation (AOP) applying the photo- Fenton process in order to evaluate the feasibility of water reuse in the textile industry production process. Reactions were conducted in a bench photo-reactor with radiation, both UV and UV-vis and testing Iron Sulfate and Ferrioxalate as Iron (II) sources. Also, an experimental design was followed in which initial concentrations of Fe(II) and H2O2 varied from 4-20mg/L and 100-500mg/l, respectively. Response variables monitored were TOC (mg/L) and residual H2O2 (mg/L). For a pH equals 3 in a molar rate of Fe/H2O2 ≈ 0,4:3, TOC reduction obtained was 98,4% and residual concentration of H2O2 was 2,6 mg/l. Results favor textile wastewater reuse after AOP treatment.
