  • What is the cod and pH of untreated dye bath wastewater?
  • COD and pH of the untreated wastewater were measured as 787 ppm and 9.24 respectively. The coagulation and the Fenton oxidation techniques were performed for the real dye bath wastewater collected. 3.4.1.
  • Does chemical coagulation and Fenton oxidation reduce reactive Black 5 dye?
  • The application of chemical coagulation and Fenton oxidation on the color and the chemical oxygen demand (COD) reduction of Reactive Black 5 (RB 5) dye solu-tion, the synthetic textile wastewater (STW), and the real dye bath real textile wastewater (RTW), was investigated.
  • Can coagulation reduce Cod and color of industrial wastewater?
  • The coagulation process has been successfully applied to reduce chemical oxygen demand (COD) and other water quality parameters of industrial wastewater . Greater than 90% reduction of COD and color of pulp and paper industry effluents was achieved by coagulation with alum .
  • Does Fenton oxidation decolorize real dye bath wastewater?
  • The Fenton oxi-dation successfully decolorized 87% of hypersaline STW at pH 3. All three coagulants successfully decolorized real dye bath wastewater and showed around 80% color reduction at 400 coagulant dosages. The Fenton oxidation with 0.5 mM H 2O and 0.05 mM Fe2+ decomposed more than 80% of real 2 dye bath wastewater.
