Chemical Oxygen Demand (COD)

Chemical Oxygen Demand (COD) measures the amount of oxygen required to break down organic pollutants in water through a chemical process. It indicates the level of organic material, such as waste or natural organic matter, present in the water. Higher COD values mean more organic pollution, which can deplete oxygen levels in aquatic environments, harming fish and other organisms. COD testing helps assess water quality and the effectiveness of treatment processes, ensuring water is safe and environmentally compliant. It’s a key parameter in managing wastewater and protecting water resources.
