  • 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.
  • 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 .
  • Is water color removal still a process?
  • Wastewater color removal is a process that must be assessed on a case-by-case basis. Chemical/physical methods are certainly still common used. Advanced chemical oxidation processes are the most promising ones today. Electrochemical and biological processes must still be adequately studied.
  • Do COAG ulants decolorize STW?
  • All three coag-ulants showed less efficiency in color reduction and failed to decolorize STW regardless of the dosage or the pH of the dye wastewater. This may be due to the high stability of dispersed dye molecules in the highly saline wastewater solution.
