Abstract

YARCE-CASTANO, Jaleimy et al. Study of the effect of radiation intensity and H₂O₂ concentration in the treatment of effluent from the textile industry with UV/H₂O₂. Ing. compet. [online]. 2022, vol.24, n.1, e22511308.  Epub Oct 30, 2021. ISSN 0123-3033.  https://doi.org/10.25100/iyc.24i1.11308.

A large amount of textile wastewater containing various toxic chemicals is discharged daily, posing a risk to ecosystems and human health. Since the processes of conventional municipal wastewater treatment plants do not effectively remove these compounds, in this study, the actual treatment of textile wastewater was evaluated by a tertiary treatment with the advanced oxidation process, UV/H2O2 based. A pre-treatment consisting of filtration and neutralization was applied, followed by a UV/H2O2 treatment varying the concentration of H2O2, the intensity of the radiation was also varied using a set of 15 W power lamps each. The best degradation condition was obtained with a H2O2 0.10 M and a radiation intensity of 45 W, considering an energy consumption evaluation of the treatment.

Keywords : advanced oxidation processes; energy consumption analysis; real textile wastewater; radiative power.
