Continuous Emission Monitoring Systems (CEMS & OCEMS)

Real-Time Regulatory Telemetry and Data Integrity

For high-pollution potential industries categorized under the Central Pollution Control Board’s (CPCB) 17 Categories of Highly Polluting Industries—including pharmaceuticals, pesticides, dyes, petrochemicals, and metallurgy—real-time emission reporting is a strict operational mandate. Regulatory bodies require continuous, tamper-proof streaming of stack emissions and treated effluent data directly to State Pollution Control Board (SPCB) and CPCB central servers.

We provide comprehensive, end-to-end Continuous Emission Monitoring Systems (CEMS) and Online Continuous Effluent Monitoring Systems (OCEMS). Our services bridge the gap between complex analytical instrumentation and robust digital telemetry, ensuring your facility maintains uninterrupted compliance, eliminates data-gap penalties, and achieves complete operational transparency.

Our Technology Spectrum

We design and commission monitoring suites tailored to the physical and chemical nature of your industrial discharge:

1. Gaseous CEMS (Stack Emission Monitoring)

Engineered to analyze and report flue gas components and process vent pollutants continuously under extreme temperature, moisture, and dust conditions.

  • Extractive Systems (Hot-Wet & Cold-Dry): Utilizing advanced Multi-Gas Analyzers based on Non-Dispersive Infrared (NDIR), Fourier-Transform Infrared (FTIR), or Chemiluminescence technologies to monitor SO2, NOx, CO, CO2, and O2.
  • In-Situ Analyzers: Laser-diode (TDLAS) systems for highly reactive gases like HCl, NH3, or HF, measuring parameters directly across the stack diameter without sample extraction.
  • Particulate Matter (PM) CEMS: Utilizing Opacity, Light Scattering, or Electrodynamic technologies to track dust and ash loads post-APCM filtration blocks.

2. Online Continuous Effluent Monitoring Systems (OCEMS)

Deployed at final ETP/STP discharge outlets or critical reuse junctions to monitor liquid discharge streams or confirm true Zero Liquid Discharge (ZLD) status.

  • Organic Load Tracking: UV-Vis Absorption and high-temperature TOC (Total Organic Carbon) Analyzers providing real-time, correlated values for COD and BOD.
  • Physical Parameters: High-precision, automated sensors for pH, Total Dissolved Solids (TDS), Electrical Conductivity, and Temperature.
  • Volumetric Flow Telemetry: Electromagnetic and Ultrasonic Flow Meters integrated with digital totalizers to verify actual volume allocations against consented limits.

 

Data Acquisition, Telemetry & CPCB Compliance

The Data Integrity Guarantee: Hardware is only as good as its connection. Our systems feature integrated Data Acquisition Systems (DAS) and Data Logging Software that are fully validated against CPCB guidelines. We ensure secure, encrypted, two-way data transmission via RTUs (Remote Terminal Units) to central SPCB/CPCB servers with a guaranteed data availability metric greater than 95%.

  • Automated Calibration Systems: Built-in auto-zero and auto-span calibration cycles using certified reference gas cylinders, preventing sensor drift and satisfying statutory remote audit protocols.
  • Tamper-Evident Architecture: System enclosures equipped with digital loggers tracking door-open status, calibration adjustments, and power interruptions to protect your facility during regulatory evaluations.
  • Early Warning Diagnostic Dashboards: Local touchscreens provide plant operators with predictive alarms before emission parameters approach maximum permissible consent thresholds, allowing active adjustments to ETP or scrubbing systems.
