Chemical Oxygen Demand (COD) is used as an indirect measurement of the sum of oxidizable matter in water and measures the equivalent amount of oxygen required to oxidize organic compounds. Wastewater commonly contains organic compounds, as a result of industrial processes, which can oxidise in the presence of dissolved oxygen in the water.
