Measuring total chemical pollution load to protect water bodies and ensure compliance.
A COD sensor measures the Chemical Oxygen Demand of water or wastewater, which represents the amount of oxygen required to chemically oxidize organic and inorganic pollutants present in a sample. COD is a critical indicator of overall pollution load.
Online COD sensors estimate pollution load using optical, electrochemical, or UV absorption techniques. These methods correlate measured signals with laboratory COD values through calibration models.
The measured value directly represents the estimated oxygen demand caused by chemical pollutants.
COD trends indirectly indicate organic load variation, treatment efficiency, shock loads in effluent, and potential regulatory non-compliance.
With Industrial IoT integration, COD sensors enable real-time pollution tracking, automated treatment optimization, early warning of effluent violations, and continuous environmental compliance reporting.
The COD Sensor quantifies chemical pollution at scale. By converting complex contamination into a single actionable metric, it empowers industries to treat wastewater responsibly and protect natural ecosystems.
