  • What are the chemical approaches for textile dye wastewater treatment?
  • Chemical approaches for textile dye wastewater treatment, including coagulation-flocculation (A), photocatalytic degradation of toxic dye molecules (B), photo-Fenton (C), electro-Fenton (D), electrocoagulation (E), and anodic oxidation approach (F). 3.2.1. Coagulation-flocculation
  • What methods are used to treat dye waste?
  • The treatment of wastewater containing dyes has been achieved by chemical (ozonation, Fenton reagents photocatalysis), physical (adsorption, filtration, ion exchange), and biological methods (enzymes and microbes). On the other hand, these methods for treating dye wastes have their benefits and disadvantages as described in Table 8.
  • What technologies are used to treat dye industry wastewater?
  • Various technologies such as advanced oxidation process, membrane filtration technique, microbial technologies, bio-electrochemical degradation, photocatalytic degradation have been reported for treatment of dye industry wastewater [ 3, 21–24 ].
  • What coagulants are used to remove dye from industrial wastewater?
  • Tamarindus indica and Azadirachta indica have been reported as highly effective natural coagulants for dye removal from industrial wastewater effluents (Mathuram et al., 2018). In the coagulation-flocculation approach, several chemical coagulants were also used.
