Stay Compliant.
Stay Ahead.
Our OCEMS (Online Continuous Effluent Monitoring System) enables industries to monitor wastewater discharge in real-time, ensuring compliance with regulations set by the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs).
Whether you’re in pharmaceuticals, textiles, food processing, or manufacturing, our plug-and-play effluent monitoring solutions help you stay compliant, avoid penalties, and uphold environmental integrity—all while considering Indian weather conditions and system usage
Why OCEMS is Mandatory?
OCEMS Guidelines for Effluent Monitoring (as per CPCB)
As per CPCB guidelines (dated 10th July 2018), industries with high pollution potential must install Online Continuous Effluent Monitoring Systems (OCEMS) or real-time monitoring and regulatory compliance.
- Mandatory for highly polluting industries and CETPs.
- Monitor pH, BOD, COD, TSS, TDS, Ammoniacal Nitrogen, Flow, etc.
- Install OCEMS at the final discharge outlet after treatment.
- Transmit Data live to CPCB and SPCBs via a secure network.
- Calibrate analyzers at least once every six months.
- Audit annually by CPCB/SPCB-approved third-party agencies.
- Use Certified Instruments (TUV, MCERTS, USEPA, or equivalent).
- Industry Responsible for installation, operation, and data integrity.
- Non-Compliance may lead to penalties or closure action.
Problems Solved by OCEMS
- Lack of real-time pollutant discharge data
- Manual monitoring delays & human error
- Limited transparency in pollution control
- Regulatory blind spots due to infrequent inspections
- Difficulty in identifying non-compliant units
- Complex, time-consuming lab sampling methods
CPCB Guidelines for OCEMS
As per Section 18(1)(b) of the Water and Air Acts:
Mandatory for 17 categories of highly polluting industries and common pollution treatment units
Data must be transmitted to SPCB/PCC and CPCB servers
Zero Liquid Discharge (ZLD) industries must install surveillance systems
Systems must be tamper-proof, have online calibration, and ensure 24x7 operation
Guidelines are enforced under the Environment (Protection) Act, 1986
Where is OCEMS Applicable?
17 Categories of Highly Polluting Industries:
Pulp & Paper, Distilleries, Sugar, Tanneries, Power Plants, Iron & Steel, Cement, Oil Refineries, Fertilizers, Chlor-Alkali, Dyes, Pesticides, Zinc, Copper, Aluminum, Petrochemicals, Pharmaceuticals.
Other Mandatory Units:
Parameters Monitored by OCEMS
Effluent Quality:
- COD, BOD, TSS, TDS
- pH, Conductivity, DO
- NH4-N, NO3, NO2
- Oil in Water, Flow, MLSS
- Salinity, Chlorophyll A & B
- CDOM, FDOM, Color
- Blue Green Algae
How It Works – 3-Step Flow of OCEMS
Sampling & Smart Sensing
Effluent from ETP/STP outlet is drawn into the OPRUSS OPM 300.
Smart sensors detect real-time values of pH, COD, BOD, TSS, and more.
Data Analysis & Validation
Data is analyzed using internal calibration logic, with built-in validation to ensure high precision and fault tolerance.
Real-Time Reporting
Processed data is transmitted to SPCB/CPCB servers via cloud.
This ensures regulatory compliance and real-time visibility to operators and regulators.

Case Study Highlight
Seamless OCEMS Implementation Across 4 STPs
PT Ecological Services (PTESPL) successfully deployed the OPRUSS OPM 300 Online Continuous Effluent Monitoring System at four Sewage Treatment Plants (STPs) to meet stringent CPCB compliance norms. The system was tailored to monitor critical parameters—pH, COD, BOD, and TSS—ensuring real-time and accurate pollution tracking.
The project began with technical consultations, requirement analysis, and detailed system demonstrations. Our expert team, in collaboration with client stakeholders, finalized the solution design and completed the installation within 25 days, despite COVID-related restrictions.
Highlights:
- End-to-end project execution with CPCB server integration
- Clear sensor labeling, directional piping, and visual system diagrams
- Full safety compliance and transparent reporting during the pandemic
- Exceptional coordination between PTESPL and the client teams
This case showcases PTESPL’s commitment to precision, communication, and customized pollution monitoring solutions—delivering not just a product, but peace of mind.
