| biochemical oxygen demand |
Biochemical oxygen demand, generally referred to as BOD, is a measure of the oxygen utilized by bacteria to reduce the organic material contained in wastewater. It is simply an indicator of the organic strength of wastewater. As the strength of wastewater increases, greater amounts of energy are required to clean the wastewater while increasing the costs as well.
