Chemical Oxygen Demand definition

Chemical Oxygen Demand means a measure of the oxygen required to oxidize all compounds, both organic and inorganic, in water.
Chemical Oxygen Demand or "COD" means the quantity of oxygen utilized in the chemical oxidation of wastewater under standard laboratory procedures.
Chemical Oxygen Demand means the measurement of the quantity of dissolved oxygen, expressed in milligrams per liter (mg/L, required for the chemical oxidation of decomposable matter under aerobic conditions).
