What is a COD meter?

A COD meter (Chemical Oxygen Demand meter) is a device used to measure the amount of oxygen required to oxidize organic matter in water. COD is an important indicator in wastewater treatment and water quality testing, especially for managing wastewater discharged from factories. A high COD level indicates a high amount of organic matter in the sample, meaning that the water is more polluted.

COD meters use a strong oxidizing agent to react with organic matter in the sample, and measure the oxygen consumption during the oxidation process. The higher the oxygen demand, the more organic material is present, signaling greater pollution. COD meters play a crucial role in water quality management and environmental monitoring.

Application of COD meter

✅Industrial Wastewater Management
Regular measurement of the COD in wastewater discharged from factories ensures that the wastewater is being treated properly. High COD levels indicate the need for additional treatment to prevent environmental pollution.
✅Monitoring Water Quality in Rivers and Lakes
COD meters are used to monitor the water quality of rivers and lakes. High COD values indicate that pollution from agricultural runoff or industrial wastewater may be affecting water quality. Regular testing helps detect pollution early and take corrective actions.
✅Monitoring in Sewage Treatment Plants
In sewage treatment plants, COD meters are used to assess the quality of water after treatment. They help ensure that the water meets environmental standards and determine if additional treatment is needed when COD levels exceed allowable limits.
✅Testing Drinking Water
COD meters are used to measure organic matter in drinking water to ensure its safety. High COD levels suggest that organic material is present in excessive amounts, which could indicate degraded water quality, necessitating enhanced treatment.
