ENDRESS+HAUSER  CAT860-AAE11A2A100TA

Automatic sample conditioning system for supplying process measuring devices with filtered sample from the inlet or sludge activation phase of a wastewater treatment plant

Application

Liquiline System CAT860 enables the fully automatic collection and filtration of aqueous samples. Thanks to the modular concept, the sample preparation system can be adapted to various different process conditions. There are various order options available for this purpose. For installing the filter in the process medium, various assemblies are available as accessories. The heated version of the hoses and of the housing mean that the system can be used at temperatures as low as -20 C.

The device is designed for use in the following applications:

• Collection of aqueous samples from industrial processes
• Communal and industrial wastewater treatment plants

Your benefits

• Robust and reliable:
  • Peristaltic pump, sampling takes place free from interference
  • Samples free from particles and algae thanks to membrane filtration
  • Automatic filter backflushing with cleaner
  • Filter backflushing with air
  • Optional hose trace heating system
• Simple and user-friendly:
  • Control via a CA80 analyzer
  • Installation compatible with the Flexdip CYH112
• Cleaning and maintenance: Replacement of pump hoses and filter without using tools

Function

A peristaltic pump is used to take the sample. The sample is drawn in via the filter element, filtered and fed to the analyzer. The automatic cleaning function backflushes the filter and the sample hoses with a cleaning solution. Backflushing with a cleaning solution is performed using a vacuum pump. The cleaning valve is switched for this purpose. It is also possible to backflush the filter and the sample hoses with compressed air.
