What is difference between Biochemical Oxygen Demand and Chemical Oxygen Demand?

Natural and organic waste and detritus from the wastewater treatment plants, failing urban runoff, septic system and agriculture, whole system act as the source food for the bacteria borne in water. Thyes Bacterial decomposes that organic waste using the dissolved oxygen.  Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) both are main properties that show characteristic and strength of sewage. By using these BOD & COD the oxygen demand in wastewater tested during treatment in Sewage Treatment Plant.

What is BOD?

Firstly, BOD stands for Biological Oxygen Demand. It represents that the, how much amount of oxygen is needed and consumed by microorganism and bacteria, during the decomposition of organic matter at a specific temperature.

What is COD?

COD is term represent Chemical Oxygen Demand. It is measurement indication used for monitoring total consumption of oxygen during the reaction takes place. Mainly required for getting measurement of oxygen during the oxidize soluble and organic matter in water.

Difference between Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD)

1- BOD is a biological oxidation process in wastewater or water while COD is chemical oxidation process.

2- Biological Oxygen Demand is performed by using aerobic organism but Chemical Oxygen Demand is performed by using re-agents of chemical.

3- BOD test happens on sealed water preserved for a period of 5 days and 20 degree Celsius temperature. This gave the total oxygen amount consumed by the bacteria and aerobic organism while COD test is done using boiling sulphuric acid for a specific time and temperature.

4- The Value of BOD is lower than COD.

5- BOD value is determined in 5 days while COD value can be measured within few days.

These are the major diffrence between BOD and COD. Based on the BOD and COD strength of water and wastewater is categorised in Weak, Medium, and Strong or Very Strong.
