Coupling of the coagulation/flocculation and the anodic oxidation processes for the treatment of textile wastewater

The increased demand for textile products leads to an increase in the quantity of wastewater discharged. It becomes indeed one of the most critical health and environmental problems in the world. The main challenge, therefore, is to develop innovative techniques for treating this wastewater with low...
