How are dissolved oxygen and bod related
WebDissolved oxygen (hereafter abbreviated as DO) is oxygen (O 2) dissolved in water, and in the world of nature, it is dissolved in water in proportion to the partial pressure of O 2 in the atmosphere. Dissolved oxygen levels are expressed as the amount of O 2 dissolved per unit volume of water (mg/L). It is known that the saturation level of O 2 dissolved in … WebBOD is the amount of oxygen that will be consumed by bacteria or other aerobic microorganisms while decomposing organic matter under aerobic conditions.

Webenters a system faster than it can be degraded, dissolved oxygen levels can drop below the minimum level required by aquatic organisms. In extreme cases, all of the dissolved oxygen may be removed, making the stream “anoxic”. When this happens, most organisms die, thus adding more BOD to the system and further increasing the oxygen demand.
