Understanding Chemical Oxygen Demand (COD) in Wastewater: Importance, Analysis, and Environmental Impact
The physical, chemical, and biological properties of water are referred to as its quality. It matters because it has an impact on how effectively people, animals, and plants can endure life. Pollutants, climate change, land use, and other factors can all have an impact on water quality. Water that has been used for bathing, cooking, or toilet flushing is referred to as wastewater. It contains a wide range of pollutants, such as human waste, leftover food, and detergents that contain organic, inorganic, and pathogenic material. If wastewater is not properly treated, it can contribute significantly to water pollution. Wastewater's COD acts as a measure of the level of organic matter present. The COD of wastewater is significant because it can show whether pollution is a possibility. High COD levels can harm aquatic life by reducing the amount of dissolved oxygen in the water. COD may contain pathogens that can lead to disease, which makes it a potential health risk. What is C...
