Oct 1, 1997 · The factors that determine chemical oxygen demand (COD) in Tokyo Bay have been examined by using monthly data, taken during 1980‐89, of COD, solar radiation, SST, inorganic nitrogen, and phosphate phosphorus to clarify the factors contributing to the organic contamination of the bay water.

What is Chemical Oxygen Demand (COD)? Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving waters.

The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency. This test is based on the fact that a strong oxidizing agent, under acidic conditions, can fully oxidize almost any organic compound to carbon dioxide. The COD is the amount of oxygen consumed to

COD 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.
