Continuous COD Monitoring for Better Wastewater Control

The Liquiline System CA80COD is designed for applications where continuous monitoring of chemical oxygen demand is important for understanding wastewater quality and treatment performance.

Compared with periodic laboratory testing, online COD measurement provides faster process information, helping operators identify changes in wastewater load and adjust treatment strategies more effectively.

Reliable Colorimetric Measurement Principle

The CA80COD uses a proven colorimetric measurement principle to determine COD values.

The analyzer automatically processes samples and provides continuous measurement data, making it suitable for demanding wastewater monitoring applications where stable and repeatable results are required.

Designed for Municipal and Industrial Wastewater

The analyzer is mainly used in wastewater treatment processes, including:

• 
  Plant inlet monitoring
  
• 
  Treatment process monitoring
  
• 
  Final discharge monitoring
  
• 
  Industrial wastewater control
  

It helps users evaluate treatment efficiency, support discharge monitoring and improve process transparency.

Reduce Maintenance with Automatic Functions

The CA80COD includes automatic calibration and cleaning functions, reducing manual intervention and helping maintain measurement availability.

Configurable measuring, cleaning and calibration intervals allow the analyzer to adapt to different process conditions.

Flexible Integration with Liquiline Platform

As part of the Liquiline System family, the CA80COD can be integrated into Endress+Hauser analytical systems and expanded with compatible digital Memosens sensors.

This allows users to build complete analysis stations according to their process requirements.

Supporting Process Documentation and Compliance

Continuous COD monitoring provides valuable data for wastewater quality management, process optimization and reporting requirements.

For industrial wastewater applications, COD measurement can also support wastewater load monitoring and discharge management.
