With BOD, What You See is Often Not What You Get: The Difficulty with Accurate Testing for BOD in Industrial Stormwater Runoff.
Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an ...

Measuring Short-Term BOD
Measurement of oxygen uptake rates in activated sludge processes is essential to their satisfactory operation. Traditionally, oxygen uptake rates (OUR) have been determined by using a dissolved oxygen probe to measure the change in dissolved oxygen in a BOD bottle. While this method is rapid, it provides only a snapshot, at a single point in time, of the oxygen uptake rate reaction in a treatment ...
