An Online Continuous Emission/Effluent Monitoring System is a set of analysers that measure pollutants continuously and send the data to CPCB and the State Pollution Control Board. It is required for highly polluting industry categories and any other units the Board directs.
Each unit's limits are set in its consent from GPCB and depend on where the effluent goes. Under India's general standards for discharge to inland surface water, COD is 250 mg/L and BOD is 30 mg/L. Always check your own consent first.
Common causes are power cuts, network or internet failures, data logger faults and analysers taken out for maintenance. Record every outage with its cause and time, so gaps can be explained.
Follow the manufacturer's schedule and CPCB's calibration guidelines. Probes in effluent foul quickly, so regular cleaning and checks against buffer solutions are good practice.
COD (chemical oxygen demand) measures the oxygen needed to oxidise pollutants chemically. BOD (biochemical oxygen demand) measures the oxygen used by microbes over 3 days in India or 5 days in the EU. BOD is normally lower than COD.
A Common Effluent Treatment Plant treats the combined effluent of many units in an industrial estate. It sets inlet limits for its members and monitors the quality of what each one sends.
Licensed sites in Ireland report each year on their emissions and monitoring results, incidents, complaints and environmental management programme, in the format the EPA sets.
The site must notify the EPA, investigate and take corrective action. Repeated or serious breaches can lead to EPA enforcement, including prosecution.
