COD Reduction and Removal in Wastewater | Arvia Technology
Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water and is expressed in milligrams per litre (mg/L) or parts per million (ppm). The most common application of COD is in quantifying the amount of oxidisable pollutants found in water. A COD test can be used to decipher the level of organics in water.
