Despite the usage of remarkably poisonous reagents, COD is made use of since the reactions make sure the whole oxidation with the Uncooked material, as opposed to proposals exactly where the alter in oxidizing brokers will not allow this type of response.
BOD and COD correlate with one another in pretty much all samples, but BOD is always lower than COD given that the biochemical breakdown of organics is commonly not as entire since the chemical system.
COD is most suitable for speedy and Recurrent monitoring of remedy plant effectiveness and water high-quality.
Chemical Oxygen Demand is an important evaluate in being familiar with the level of natural and organic pollutants present in surface h2o or wastewater. It really is expressed in milligrams for every liter (mg/L), which indicates the mass of oxygen eaten for each liter of Resolution.
