theoretical oxygen demand;ThOD
Molecular formula :

nature : the water of a particular theory of organic oxygen demand. Usually refers to the organic carbon and hydrogen elements for the complete oxidation of carbon dioxide and water by the strength of the theoretical value (based on complete oxidation reaction calculate the oxygen demand, as units g / g). In the strict sense but also organic nitrogen, phosphorus, sulfur and other elements complete oxidation by the strength of the theoretical value (when these elements included in the complete oxidation in oxygen demand when data indicated). Theoretical Oxygen Demand normally used for oxygen demand estimate; For comparison with the chemical oxygen demand, the research and testing to the COD determination of applicability and reliability of data; Also used with the BOD contrast, the study of pollutants in the water biodegradable wastewater characteristics and biochemical treatment, the applicability of .
