remove chemical oxygen demand (COD) from the wastewater. Thus, a biodegradation process was used to further treat the effluent of the Fenton-like process. After 12 h of aerobic activated sludge process, 90% of COD was removed, and the pH value of the effluent ranged from 8 to 9. In addition,

Wastewater COD - Why it is Critical in Wastewater Treatment?
Wastewater COD - Why it is Critical in Wastewater Treatment?

Wastewater COD, (,Chemical Oxygen Demand,) is the amount of oxygen necessary to oxidize the organic carbon completely to CO2 and H2O. Some organic chemicals are not completely oxidized. However, ,COD, is measured in approximately 3 hours via oxidation with potassium dichromate (K2Cr2O7) in the presence of Sulfuric ,Acid, and Silver Sulphate.
