**4. Conclusions**

The use of novel EC reactor in textile wastewater treatment exhibits a higher removal efficiency than the erstwhile models. The efficiency of the textile effluence pollutant removal with high values was achieved using a lower CD, precisely 4 mA/cm<sup>2</sup> , at initial reaction period (10 min) at 1 cm interelectrode distance (IED) and 150 rpm anode rotation speed. A rise in the value of CD enhanced the efficiency of EC process in the treatment of textile wastewater. The setting of the solution pH to increase the solution temperature and the addition of any chemicals (Na2 SO<sup>4</sup> or NaCl) is not required. The economic viability of the operation of the reactor is influenced by the parameters. The energy and electrode consumption of the EC increases as the CD increases. The optimal energy and electrode consumptions were 0.038 kg/m<sup>3</sup> and 0.966 kWh/m<sup>3</sup> , which led to the lower cost of operation (0.283US\$/m<sup>3</sup> ). The novel EC reactor with rotating anode significantly enhanced the textile wastewater treatment by improving the pollutant removal rate, reducing reaction time of treatment, without any additional chemicals during the process, and reducing the operation cost compared to conventional model (EC and EC-EO). It was found that the passivation phenomenon reduced with the increased rotation speed of anode, which enhanced the EC process performance and validated the novel reactor design.
