“…Pazdzior et al (2015)proposed an integrated process where concentrate from the membrane process was treated biologically (90% removal of color). Advanced oxidation processes that use ozonation (Panda and Mathews, 2014), ultra-violet/ hydrogen-per-oxide (Basturk and Karatas, 2015), and Fenton oxidation (Soares et al, 2015) are also effective in dye removal, but they are not economical and easy to use in most cases. On the other hands, biodegradation of dye is a challenge not only because of the low BOD/COD ratio but also the presence of metals, metalloids, salts, and other toxicants (Imran et al, 2015).…”

The presence of residual dyesin textile effluent is not desired as they are very toxic to the ecosystem components and carcinogenic in nature. The removal of reactive azo dye Remazol Brilliant Orange 3RID (RBO3RID) and anthraquinone dye Reactive Blue MR (RBMR) by nanoscale zero-valent iron (NZVI) particles was investigated in this study. The dyes were degraded up to 97%by NZVI particles under different experimental conditions likeNZVI dosages (0.15-0.3 g/L), initial dye concentrations (100-500 mg/L), and pH values (2-12). NZVIwas found to work the best in the pH range of 8-12 which is the typical range of pH in textile wastewater. One gram of NZVI could remove up to 2757mg of RBO3RID dye and 2207 mg of RBMR dye, and more than 80% dye removal was achieved within the first 15 minutes of reaction. FT-IR analyses showed the end products after the degradation are amines.

“…33 The results obtained in this research are in agreement with those of the studied literature, where the faster RO 16 decolourisation process with ozone oxidation compared to RB 19 is confirmed. 34 The smallest decolourisation rate of DR 28 could be explained by the large aromatic molecule with two conjugated azo groups (chromophores), which intensify the colour of the dye leading to the prolonged time of the oxidation process.…”

In this paper, the results of decolourisation of Reactive Orange 16 (RO 16), Reactive Blue 19 (RB 19) and Direct Red 28 (DR 28) textile dyes in aqueous solution by plasma needle are presented. Treatment time, feed gas flow rate (1, 4 and 8 dm 3 min-1) and gas composition (Ar, Ar/O 2) were optimized to achieve the best performance of the plasma treatment. An artificial neural network (ANN) was used for the prediction of parameters relevant for the decolourisation outcome. It was found that more than 95 % decolourisation could be achieved for all three dyes after plasma treatment, although the decolourisation of DR 28 was much slower than those of the other two dyes, which could be explained by the complexity of its molecular structure. It was concluded that the oxidation was very dependent on all three mentioned parameters. The ANN predicted the treatment time as the crucial factor for decolourisation performance of RO 16 and DR 28, while the Ar flow rate was the most relevant for RB 19 decolourisation. The obtained results suggest that the plasma needle is a promising tool for the oxidation of organic pollutants and that an ANN could be used for optimization of the treatment parameters to achieve high removal rates.

The “reactive” dyeing of textiles requires an application of low-molecular-weight salts (LMWS), such as NaCl or Na2SO4, as necessary auxiliary agents. LMWS acts only as a remediation factor and remains in the dyeing effluents constitute brine. The main goal of the presented study was to investigate the application of ozone technology for industrial textile wastewater highly polluted by LMWS. The study was divided into two parts. In Part 1, by-products accumulated during multi-recycling of the same wastewater was investigated. While Part 2 was devoted to the scaling up of ozonation process, Part 1 concerns the efficiency of textile wastewater ozonation carried out as a repeatable process. The sequence of wastewater treatment and textile dyeing was repeated four times in a closed loop using the same process water. Although the wastewater decolorization was efficient in the subsequent ozonation cycles, some adverse effects, such as an increase in chemical oxygen demand (COD) and self-buffering at pH 9.5–10.0, were suggested the accumulation of by-products. The preliminary detection of by-products by thin layer chromatography (TLC) revealed phenol and naphthol derivatives as the transformation products (TPs) of ozonation. Dyeing of cotton using purified wastewater (brine) resulted in very good DECMC color matching parameters (under 1.16), but only in the first recycling loop, and then the TPs affected the process.
