Reliable Ammonium Monitoring for Wastewater Processes

The Liquiline System CA80AM is designed for applications where continuous ammonium monitoring is important for maintaining stable wastewater treatment performance.

Instead of relying only on laboratory sampling, the analyzer provides regular online measurement data, helping operators understand process conditions and optimize treatment performance.

High-Precision Colorimetric Measurement

The CA80AM uses the standardized indophenol blue colorimetric method according to recognized standards including ISO 7150-1, DIN 38406-5 and GB 7481-87.

This proven measurement principle provides reliable ammonium analysis for demanding wastewater monitoring applications.

Designed for Municipal and Industrial Wastewater

The analyzer is mainly used in wastewater treatment processes where ammonium levels directly influence biological treatment efficiency.

Typical monitoring points include:

• 
  Wastewater plant inlet
  
• 
  Biological aeration basins
  
• 
  Treatment plant outlet
  
• 
  Industrial wastewater treatment processes
  

Reduce Maintenance with Automatic Functions

The CA80AM includes automatic calibration and cleaning functions, helping reduce manual maintenance work and improve measurement availability.

Optional cooling modules can extend reagent lifetime, while configurable measuring, cleaning and calibration intervals allow adaptation to different process requirements.

Flexible Integration with Liquiline Platform

As part of the Liquiline analysis platform, the CA80AM can be integrated into complete measuring stations and combined with additional digital sensors using Memosens technology.

This modular approach allows users to expand measurement capabilities according to future process needs.

Support Process Optimization and Compliance

Continuous ammonium monitoring helps operators optimize biological treatment processes and provides measurement records for wastewater quality documentation.

The analyzer also supports remote access options through digital communication interfaces depending on configuration.
