Description

Liquiline System CA80COD offers constant online measurement of the chemical oxygen demand (COD). It supports you in monitoring the cleaning capacity of wastewater treatment plants and enables load-based billing for industrial dischargers. Automatic calibration and cleaning save operating costs while advanced diagnostics with remote access help to provide process documentation to authorities. The COD analyzer's software-controlled safety functions ensure the highest level of occupational safety.

Field of application

The Liquiline System COD analyzer monitors:

  • Inlet and outlet of wastewater treatment plants for documentation purposes and calculation of the cleaning capacity
  • Discharges of industrial wastewater treatment plants to determine discharge fees and to support the polluter-pays-principle
  • Process water
