WebJun 7, 2024 · The COD is a quicker method of estimating the oxygen demand of a sample. The COD actually represents the ultimate BOD (BOD u) or the amount of dissolved oxygen to completely oxidize the organic matter in a sample, and the COD will always exceed BOD 5. The BOD 5 concentration typically is around 65 percent of the COD concentration. WebApr 2, 2024 · The amount of dissolved oxygen used up by aerobic microorganisms to decompose the organic matters present in a sample of water is termed Biochemical Oxygen Demand or Biological Oxygen Demand (BOD).

The COD test is more robust than BOD because not all organic matter is readily oxidized by bacteria. Additionally, other chemicals, and inorganic substances in the water can be oxidized by dichromate.

WebCOD Testing Advantages. COD is most suitable for rapid and frequent monitoring of treatment plant efficiency and water quality. This method is more accurate than BOD (with a 5-10% relative standard deviation) and it offers a relatively short analysis time (2-hour digestion time), compared to the 5-day BOD test.
