Web1- 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 … WebSep 12, 2024 · The dissolved oxygen readings are usually in parts per million (ppm). Higher BOD indicates more oxygen is required, which is less for oxygen-demanding species to feed on, and signifies lower water quality. Inversely, low BOD means less oxygen is being removed from water, so water is generally purer.
WebJun 19, 2015 · COD is the amount of oxygen required to chemically breakdown the pollutants. Whereas BOD is the amount of oxygen required to do this biologically through micro-organisms.

The COD value of chemical oxygen demand is generally higher than the BOD5 value of biochemical oxygen demand, and the difference between them can roughly reflect the content of organic matter in sewage that cannot be degraded by microorganisms.
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.
