COD (Chemical Oxygen Demand)

Chemical Oxygen Demand (COD) is a measure of the amount of oxygen that microorganisms will consume while decomposing organic matter in water. It indicates the level of pollution and the organic material present in water, helping to assess water quality and the effectiveness of wastewater treatment processes. A higher COD value suggests more pollution, as it means there’s more material for bacteria to break down. Monitoring COD is essential for environmental health, as it helps ensure that water bodies remain safe for ecosystems and human use.
