Photocatalytic degradation of real textile wastewater using carbon black-NbO composite catalyst under UV/Vis irradiation.

This work investigated the impregnation of NbO into carbon black (CB) in different ratios and its effect in photocatalytic degradation of real wastewater from a dyeing factory by advanced oxidative processes (AOP). Synthesized catalysts were characterized regarding their crystalline structure (DRX, micro-Raman), morphology (MEV), textural (BET area) and optical properties (bandgap energy by diffuse reflectance) and pH at the point of zero charge (pH). Preliminary tests showed better photodegradation results in the acidic medium after 5 h of irradiation with NCB-0.

Coagulation/flocculation of textile effluent using a natural coagulant extracted from Dillenia indica.

The aim of this study was to assess the efficiency of mucilage extracted from the fruit of Dillenia indica for enhancing coagulation in the treatment of textile effluent. The mucilage extraction was carried out in water at room temperature. The pH, concentration of coagulant FeCl.
