Explanation of methods to lower COD and how to measure COD!
COD (Chemical Oxygen Demand) refers to the degree of pollution caused by organic matter (contaminants) in marine and lake environments, represented by a numerical value. A higher COD indicates a greater amount of organic matter (contaminants) in the water, meaning that there are more substances that readily react with oxygen present. BOD (Biochemical Oxygen Demand) is often confused with COD. While both are indicators of water pollution, there are key differences: COD: Represents the degree of pollution in lakes and marine areas, measured using oxidizing agents. BOD: Represents the degree of pollution in rivers, measuring the amount of oxygen consumed by microorganisms over five days. *For more detailed information, please refer to the related links.
