How to calibrate the chemical oxygen demand value through the controller？

Chemical Oxygen Demand (COD) refers to the amount of oxygen required for the oxidation of organic matter in water under certain conditions. It is an indicator that measures the content of organic matter in water and the degree of water pollution. COD is one of the indicators for evaluating the content of organic matter and water quality in water bodies. During the water treatment process, monitoring COD can help determine the appropriate treatment process and dosage of treatment agents to meet water quality standards. This video shows how to calibrate the COD value through the daruifuno DUC2-COD model online COD controller.
