Chemical Oxygen Demand (COD)

Chemical Oxygen Demand (COD) is a key parameter used to measure the amount of oxygen required to chemically oxidize organic and inorganic compounds in water. It serves as an indicator of the overall pollution level and organic content in water bodies. High COD levels signify a greater presence of organic pollutants, such as industrial effluents or wastewater discharges, which can lead to oxygen depletion when these compounds decompose.

Monitoring COD levels is crucial for assessing the effectiveness of wastewater treatment processes and determining the potential impact on aquatic ecosystems. By managing and reducing COD levels, water utilities can improve water quality, protect aquatic life, and ensure compliance with environmental regulations.
