COD dosage

Chemical Oxygen Demand (COD) measures the amount of oxygen required to oxidize organic matter in a liquid sample. It is a key indicator of organic pollution in wastewater or industrial water. The analysis is carried out using a standardized method (e.g., NF T90-101) with dichromate oxidation.
