“…For example, low-cost techniques, which are confirmed to be efficient as adsorption by activated carbon, are producing large quantities of solid wastes, which need further disposal, therefore adding to the environmental threats. However, the other sufficiently promising methods are not economically effective (Azbar et al 2004;Tony et al 2016). Thus, it is crucial to explore a novel alternative treatment technique that is more efficient in removing dye-water streams.…”

“…These processes are mainly dependent on highly reactive hydroxyl radicals ( ⋅ OH ); those radicals are effective on initiating the oxidation of the organic pollutants and then mineralizing them. The complete removal of pollutants leads to harmless end products, CO 2− and H 2 O (Sobczynski and Dobosz 2001;Saravanan et al 2013d;Ashour et al 2014;Azbar et al 2004;Tony et al 2016). AOPs include several photocatalytic techniques such as the combination between a semiconductor (ZnO, TiO 2 ) and UV-induced light (Legrini et al 1993;Daneshvar et al 2004).…”

The photocatalytic oxidation of methylene blue (MB) in aqueous media is explored using nanoscale ZnO nanoparticles (ZnO NPs) for maximal dye removal within the high-surface-area nanoparticle photocatalyst. The operating parameters such as illumination time, initial MB load, ZnO NP dose, solution flow rate and pH were examined. The experimental results revealed the alkaline pH (12.0) corresponding to the higher oxidation rate within only 20 min of reaction time; however, increasing the initial MB load decreased the reaction rate at the optimum circulation flow rate of 460 mL/min and ZnO NP dose of 0.4 g. Additionally, for providing maximum performance, the interaction between the most effective independent parameters (ZnO NP dose, flow rate, and initial pH) were explored using Box-Behnken experimental design based on the response surface methodology. The results showed a good fitness of the model (R 2 = 96.86%) with the experimental data. The optimum values were recorded after 20 min of reaction time with the values: 0.45 g/L for ZnO NP dose, 370 mL/min for flow rate and pH 11, showing a 94% maximum dye removal compared to 92% using manual optimization. Finally, the kinetic models were applied and the data were described by second-order kinetic model.

“…dyes and phenols (Parker et al, ; ). Recently published work also showed that S300 (starch‐derived Starbon prepared at 300ºC) was effective for the treatment of laundry wastewater (Tony et al, ). However, Starbon can also be prepared from alginic acid, resulting in materials with slightly altered textual properties.…”

Grey water from commercial laundry facility was used for treatment to substitute the conventional water sources. Algibon, A800 derived from mesoporous alginic acid and Starbon S300, carbonaceous mesoporous polysaccharide-derived materials, silica gel (SG) and activated carbon (AC) were used for the treatment of wastewater. The optimum adsorbent dosing and pH value for each adsorption system are defined. The adsorption efficiency are in the order of A800 > SG > AC > S300 and the removal rate reached to 91% when A800 was used. Furthermore, the reaction followed the second-order kinetic model and the rate constant is high when A800 adsorbent is applied.

The untreated wastewater from the dye industry having high ammoniacal nitrogen and chemical oxygen demand (COD) significantly pollutes the receiving water, such as a river, having major ill implications on the aquatic environment. The present study is undertaken to address this problem. It investigates the effectiveness of Fenton reagent in simultaneous treatment (removal) of ammoniacal nitrogen and COD present in the wastewater by varying the parameters like pH, concentration of Fe 2+ and H 2 O 2 and their molar ratio. The reaction time for all the experiments was kept 60 min. The experimental analysis in terms of calculating the residual % of ammoniacal nitrogen and COD revealed that the maximum reduction occurred at pH 3. At this pH, further set of experiments were performed by varying the molar doses of Fe 2+ /H 2 O 2 as 1:1, 3:3 and 5:5, and the results reveal that the maximum reduction in both ammoniacal nitrogen and COD happens at molar dose of 3:3. To understand the effect of the concentration of Fe 2+ and H 2 O 2 on the respective removal efficiency, set of experiments were performed by taking the molar ratio of Fe 2+ /H 2 O 2 as 2:1, 3:1, 5:1, 1:2, 1:3 and 1:5. The experimental analysis reveals that the maximum reduction happened at molar ratio 1:3. Fenton process can mineralize the pollutants up to 75.8% and 78.6% for ammoniacal nitrogen and COD removal. The findings of the study would be of great use for planning and optimizing the wastewater treatment facility for the dye intermediate industry.
