What is a Continuous Effluent Quality Monitoring System (CEQMS)?

A Continuous Effluent Quality Monitoring System is an automated online system installed at the outlet of Effluent Treatment Plants (ETPs) or Sewage Treatment Plants (STPs) to continuously monitor critical parameters of water pollution. It helps industries and authorities ensure that the treated wastewater complies with environmental standards set by the Central Pollution Control Board (CPCB).

Purpose of CEQMS

• • To monitor industrial discharge quality in real-time

• • To ensure statutory compliance with CPCB norms

• • To provide data for regulatory decision-making

• • To enable remote surveillance and alert mechanisms

Key Parameters Monitored in CEQMS

CEQMS monitors the following critical effluent parameters as per CPCB guidelines:

Physico-Chemical Parameters:

• • pH

• • Chemical Oxygen Demand (COD)

• • Biochemical Oxygen Demand (BOD)

• • Total Suspended Solids (TSS)

• • Total Dissolved Solids (TDS)

• • Ammoniacal Nitrogen

• • Nitrate, Phosphate, Chloride

Heavy Metals (if applicable):

• • Lead (Pb)

• • Arsenic (As)

• • Mercury (Hg)

• • Chromium (Cr)

These parameters are monitored 24×7, and the data is automatically transmitted to CPCB/SPCB servers via GPRS/cloud platforms.

How Does CEQMS Work?

Step-by-Step CEQMS Workflow

1. 1. Effluent Sampling – A submersible or bypass pump collects water samples.

1. 1. Sensor-Based Measurement – High-accuracy analyzers continuously test parameters.

1. 1. Data Logging – All readings are logged in real-time.

1. 1. Data Transmission – The system transmits encrypted data to CPCB’s servers using GPRS/Internet.

1. 1. Alert Mechanism – Immediate alerts on parameter breaches via email/SMS.

1. 1. Reporting & Archiving – Historical data can be analyzed for trend prediction and audits.

Who Needs to Install CEQMS?

According to the CPCB CEQMS mandate, the following sectors must install CEQMS:

• • Textile and Dyeing Units

• • Pulp and Paper Industries

• • Sugar Mills

• • Pharmaceutical Manufacturing

• • Food Processing Units

• • Distilleries

• • Common Effluent Treatment Plants (CETPs)

Any industry discharging wastewater must comply with CEQMS regulations.

Compliance with CPCB Guidelines and Integration

• • CEQMS systems must follow the latest CPCB guidelines.

• • Must have auto-calibration features and tamper-proof logging.

• • Two-way communication with CPCB servers is mandatory.

• • Annual calibration and quarterly validation by authorized third-party labs is essential.

---

Data Transmission Protocol & Connectivity

• • Data should be sent to the CPCB server via GPRS, VPN, or cloud server.

• • CEQMS must be capable of encrypted and tamper-proof transmission.

• • Compatibility with OCEEMS (Online Continuous Effluent and Emission Monitoring System) architecture is required.

---

Cost of CEQMS Setup

The cost of CEQMS varies depending on:

• • Number of parameters monitored

• • Complexity of installation (e.g. flow type, sample quality)

• • Brand and accuracy of analyzers

• • Maintenance and AMC inclusion
