| biochemical oxygen demand |
A quantitative measure of the oxygen needed by bacteria and microorganisms for the biological oxidation of organic wastes in a unit volume of waste water. BOD is generally measured in milligrams per liter (rng/1) of oxygen consumed over a five-day period. Although complete biological decomposition of, organic waste requires about 20 days, the five-day BOD is about two-thirds of the total oxygen requirement and, therefore, is a practical measure of waste concentration. ...

A gross measure of wastewater strength. The regional plant uses an accelerated treatment process in which living bacteria, thriving in an oxygen-rich environment, consume material in the wastewater. Industry wastewater that is high in BOD requires more oxygen and is therefore more expensive to process.
