Determination of biological oxygen demand (BOD)
BOD (biochemical oxygen demand) is a measure of the amount of oxygen that microorganisms need to break down the organic material in a water sample over a specific period of time. It is important to calculate the oxygen concentration at the start and end of the measuring time, which is usually five days and is expressed as an index (BOD5). Chemical, electrochemical or physical methods are used for this calculation.
