Application of the Optimized Pre-ozonation Treatment for Potential Resource Recovery from Industrial Textile Effluent

04 May 2021-Ozone-science & Engineering (Informa UK Limited)-pp 1-14
TL;DR: In this paper, an optimized pre-ozonation treatment has been proposed for textile effluent, which is optimized for high color, organic load, dissolved solids content and toxicity of the textile effluents.
Abstract: Treatment of the textile effluent becomes complex due to the high color, organic load, dissolved solids content, and toxicity of the textile effluents. An optimized pre-ozonation treatment has been...

TL;DR: In this article , an experimental study on the decolorization efficiency and degradation of organic compounds from textile wastewater by the ozonation process in a batch system was performed in a 1 L glass reactor with a magnetic stirrer and a bubble diffuser at the bottom to feed the ozone.
Abstract: ABSTRACT This is an experimental study on the decolorization efficiency and the degradation of organic compounds from textile wastewater by the ozonation process in a batch system. The effects of different sample volumes of textile wastewater over time were investigated. The experiments were performed in a 1 L glass reactor with a magnetic stirrer and a bubble diffuser at the bottom to feed the ozone. The applied cumulative ozone dosage varied at 120 gO3 L−1, 60 gO3 L−1, and 30 gO3 L−1, and the total interaction time for each test was 1 h. To investigate the physicochemical properties of the textile wastewater (solid and liquid phases) before and after the treatment, multiple analytical characterization methods were used: Thermal Gravimetric Analysis, Scanning Electron Microscopy coupled with Energy-Dispersive X-ray Spectroscopy, X-ray diffraction, Fourier Transform Infrared spectroscopy, and Spectrophotometer. The most perceptive change was observed in the color of the liquid medium, which turned from black to transparent, and a visual color number indicator known as DurchsichtFarbZahl (DFZ) was used for the evaluation of this process. Absorbance values decreased about 3.5 times after 5 min of treatment with a 0.15 L sample volume, and these values differed for tests with larger sample volumes. FTIR spectroscopy demonstrated that the bands’ intensities associated with the C − H, C − N, and C − O decrease during treatment. On the other hand, it was possible to conclude that combining treatment methods to improve the degradation of persistent compounds after the ozonation process is necessary. Finally, the ozonation of the textile wastewater proved to be effective at removing color due to its high reaction capacity. Graphical Abstract

TL;DR: In this article, a study was conducted on the efficacy of ozonation in removing dissolved organic matter (DOM) in biotreated textile effluents and effects on its biodegradability and adsorbability.
Abstract: A study was conducted on the efficacy of ozonation in removing dissolved organic matter (DOM) in biotreated textile effluents and effects on its biodegradability and adsorbability Results showed the efficient removal of color and fluorescence compounds were achieved through ozonation, due to increasing hydrophilicity and lowering molecular weight of DOM A significant biodegradability improvement was also observed, and DOM adsorbability on activated carbon was highly dependent on ozone dosage As the key parameter, consumed 38 g O3/ g TOC0 was the optimal dosage in the hybrid process combining ozonation with biological activated carbon (BAC) for wastewater reclamation
