“…It is necessary to confirm the expected figure. A pictorial explanation of the predicted outcomes should be discussed, as should the suitability of the restricted answer to the intended consequence (Darwesh et al., 2021; Ganesan & Thanasekaran, 2012; Rakhmania et al., 2022).…”

Electro‐Fenton oxidation may improve wastewater biocompatibility. In this investigation, steel flakes were used as a novel catalyst in the Enhanced Electro Fenton procedure, in place of the traditional Electro Fenton Process. A degradation study of textile dyeing effluent has been conducted using the Modified Electro Fenton process. In 60 min of reaction time in the Electro‐Fenton process, 98.57%, 95.38%, and 94.93% of color removal was achieved for reactive blue, reactive yellow, and reactive black dyes respectively. From the Laboratory‐scale feasibility studies on the Electro‐Fenton process, the utmost color and COD elimination efficiency of 93% and 70% correspondingly observed at a catalyst dosage of 1 g/L, H2O2 dosage of 132 mM at pH 3. In this study, the average coefficient of correlation was 0.9978, indicating that the framework could describe 99.78% of the variability in response. The Analysis of variance (ANOVA) of the quadratic regression analysis shows that the model is incredibly substantial, as displayed by the Fisher F‐test (F model = 347.52) with the lowest probability value (p model > F = 0.0001). The predicted results from Response Surface Methodology (RSM) closely agreed with the experimental results obtained during the optimization studies and hence confirmed the results obtained.

“…On the other hand, the electrocoagulation (EC) treatment process has great potential in many wastewater treatment methods and has been demonstrated to quickly and effectively treat wastewater that is highly polluted (Rakhmania et al, 2022). It also has outstanding practicability for replacing the disadvantageous conventional treatment with better wastewater treatment.…”

In this study, the electrocoagulation (EC) treatment was used to minimize and separate pollutants from textile industrial wastewater (TIWW), including high color, chemical oxygen demand (COD), total organic carbon (TOC), and total dissolved solids (TDS). To enhance the EC treatment efficiency, a novel strategy has been followed in the study that involves thin‐film coating on 316 stainless steel (SS) electrodes with banana peel‐derived activated carbon (BPAC) by dip coating, spin coating, or spray coating. Among the different types of coating, thickness and contact angle measurements have elucidated that the spray coating of BPAC on SS electrode is the best tool with minimum thickness and contact angle. In this study, a bare SS electrode was used as the anode and a thin‐film spray‐coated BPAC on the SS electrode was used as the cathode. Moreover, optimization plays a key role in EC treatment process, where operating conditions such as a current density of 10 mA/cm2, contact time of 15 min, and a pH of 7 were fixed. As a result, the findings indicate comparatively high color removal of 98%, COD removal of 91%, TOC removal of 89.6%, and TDS removal of 68% are achieved with ease. Accordingly, in comparison with plain SS electrodes or dip‐ or spin‐coated BPAC on SS electrodes, spray‐coated BPAC on SS electrodes in EC treatment outperforms in removing high color, TOC, COD, and TDS. Overall, the study highlights the potential of EC treatment integrated with adsorption procedures for TIWW treatment. Particularly, the use of thin‐film spray‐coated BPAC on SS electrodes in the EC treatment process led to an effective and sustainable tool for treating and reuse of TIWW. It is due to its low operation and maintenance cost and studied in a short interval of time. Finally, the ultimate goal was firmly achieved in pilot‐scale studies by the safe discharge into the environment or reuse of treated textile wastewater. Thus, it is a promising alternative with an environmentally friendly footprint that could be easily implemented in any textile industry premises.Practitioner Points Heavy metals, oils, facts, suspended solids, and other pollutants can be removed from industrial effluent by using electrocoagulation. The process is both cost‐effective and energy‐efficient, and it is easily integrated with other water treatment technologies. According to the findings of this study, minimum current density should be applied to BPAC–SS‐coated electrodes by DC power supplies to treat textile industry effluents at low operating costs. When compared with a plain SS electrode, the spray‐coated BPAC on SS electrode provides better performance in effluent treatment.
