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

What is Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) Determination? Why Should It Be Done?

"Chemical Oxygen Demand (COD) Determination" is carried out to determine the oxygen depletion capacity of water samples contaminated with organic waste materials.

It is a parameter used in determining the degree of organic pollution of domestic and industrial wastes.

Chemical Oxygen Demand (COD) is an important parameter used in determining water quality. It is usually carried out to estimate the "Biological Oxygen Demand (BOD)". It is preferred that the Chemical Oxygen Demand (COD) analysis yields results in a short time.

Biological Oxygen Demand (BOD); Within the scope of the test, it can be defined as the amount of oxygen consumed for organic substances that can be paralyzed by aerobic bacteria at a certain time and temperature.

The Biological Oxygen Demand (BOD) test is a bioassay method that is generally used to determine the bio-treatability capacity and the success of the treatment system. Biological Oxygen Demand (BOD) values ​​are used in the construction and operation of wastewater treatment plants.

Biological Oxygen Demand (BOD) is affected by many factors such as its value, the concentration of organic substances that can be degraded in water, the type and number of microorganisms, the incubation time, temperature, substances that can cause toxic effects.
