The experiment was performed successfully and COD values have been determined in the above table. Similarly Chemical Oxygen Demand COD is the demand of oxygen required to reduce dichromate Cr 2 O 72 - Cr in 6 oxidation state to Cr 3. Home current Explore Explore All.
It is normally measured in. Report BOD azida md zin. Extensive observation of the COD and BOD levels on the same wastewater has shown that the COD to BOD ratio of a particular wastewater will remain constant over time.
The purpose of this experiment is to demonstrate the principle of determining the oxygen. The Biochemical Oxygen Demand or BOD is the amount of dissolved oxygen which is used up by these microorganisms and is roughly equivalent to the amount of food organic matter found. BOD determines the relative oxygen required by aqueous microbes for the ingestion of organic materials in natural water and wastewater or any given water sample 2During the process of BOD.
