Chemical Oxygen Demand, COD tube (ChemTEST vials)
Chemical Oxygen Demand is used in water, waste water, and aqueous hazardous waste as a measurement of contaminants. The calculation of soluble Chemical Oxygen Demand in wastewater is one of the applications of the Chemical Oxygen Demand test, as characterization of total Chemical Oxygen Demand in wastewater is important for precise biotransformation modeling in wastewater treatment processes.
Another application is to rapidly infer from the Chemical Oxygen Demand tests the biodegradability of samples. By forming a connection between Chemical Oxygen Demand and Biological Oxygen Demand, this is typically done. When the proportions and types of materials in waste water remain relatively stable, this approach has been found to be efficient.
