Treatment of a dye solophenyle 4GE by coupling electrocoagulation / Nanofiltration

The study contributes in the treatment of waste generated by the textile complex cotton of Draa Ben Khedda, Algeria. The azo dye \"Direct Red Solophenyle 4GE\" represents the base particle of the discharges and electrocoagulation with nanofiltration are used as a means of treatment. The solar photovoltaic is suitable for electrochemical process to reduce the energy cost. Several study parameters are considered in this work. The electrocoagulation batch gives the best reduction 37% for a dye concentration of 7.21 mg/L ([NaCl]_added = 1 g/L; <i>j</i> = 25.2 mA/cm²). Coupling methods (electrocoagulation-nonofiltration) gives a complete discoloration rejecting concentration 52.4 mg/L (pHi = 7.6, [NaCl]_added = 3 g/L, <i>j</i> = 2.13 mA/cm²). The result shows the coupling efficiency with a reduced amount of resulting slurry at the end of treatment.
