58 Online Monitoring Stations | 53 Stack Monitoring | 5 Effluent Monitoring
Completed in 2023, Aaxis Nano Technologies deployed a 58-station online monitoring network at Bhilai Steel Plant,
strengthening continuous emission and effluent surveillance, centralised environmental data management and regulatory data connectivity.
Integrated Emission & Effluent Monitoring
The system brings together 53 Continuous Emission Monitoring Systems (CEMS) across identified stacks and plant outlets and 5 Effluent Quality Monitoring Systems (EQMS) at designated locations.
The monitoring architecture incorporates online emission analysers, moisture measurement, opacity and dust concentration monitoring, flow, pressure and temperature instrumentation, along with pH, dissolved oxygen and conductivity measurement for effluent monitoring.
The emission monitoring systems cover SO₂, NOx, PM, CO, CO₂, O₂, moisture, flue gas pressure, flue gas temperature and flue gas flow velocity. The effluent monitoring systems measure pH, TSS, COD, BOD, cyanide, phenol, effluent flow and temperature.
Centralised Data. Connected Visibility.
A central server and data acquisition infrastructure collect, store and manage information from the monitoring installations. The system supports data analysis, health and diagnostics, alarm management, registers, reporting and web-based viewing.
Real-time data from the CEMS and EQMS is linked to CPCB and CECB, supporting online regulatory data transmission from Bhilai Steel Plant. Communication interfaces including RS232, RS485 and Ethernet support connectivity between field systems and the central monitoring infrastructure.
Supporting Continuous Monitoring
The monitoring architecture provides for calibration and validation records, analyser diagnostics, operational logging and remote access, along with provisions for recording continuous operating data and maintaining measurement information for extended periods.
A five-year Comprehensive Maintenance Contract after the warranty period supports continued maintenance of the monitoring systems, helping ensure consistent operation and availability of environmental data.
Together, the connected monitoring systems provide Bhilai Steel Plant with continuous access to emission and effluent data, centralised monitoring and direct regulatory data connectivity.
