  • What is Chemical Oxygen Demand (COD)?

    Chemical Oxygen Demand (COD) analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Specifically, it measures the equivalent amount of oxygen required to chemically oxidize organic compounds in water. Why Measure COD? COD is used as a general indicator of water quality and is an integral part of all water quality ...
