Determination of Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)

Chemical Oxygen Demand (COD): the total amount of oxygen required for the decomposition of an organic substance by chemical oxidation.
Determination of Chemical Oxygen Demand (COD) is carried out by leaving a water sample containing a strong oxidizing agent under certain temperature conditions for a short time. 
Chemical Oxygen Demand (COD) Its purpose is to measure oxidizable pollutants in water, to determine how wastewater affects water bodies.

Biological Oxygen Demand (BOD): The total amount of oxygen required for microorganisms to decompose organic matter under aerobic conditions.
Determination of Biological Oxygen Demand (BOD) is performed by keeping closed water samples at a certain time and temperature. 
Biological Oxygen Demand (BOD) Purpose, waste loading in treatment plants, evaluation of BOD removal efficiency in waste plants.
