Automatic sample conditioning system for
supplying process measuring devices with filtered
sample from sludge activation, secondary
clarification or surface water
Control of sample conditioning by means of the
Liquiline System CA80 or a time control system
Application
Liquiline System CAT820 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 filters and hose
lengths 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:
- Communal and industrial wastewater treatment plants
- Surface waters
- Collection of aqueous samples from industrial processes
Your benefits
- Robust and reliable:
- Peristaltic pump, sampling takes place free from interference
- Optional compressed air cleaning system
- Optional hose and housing heating system
- Simple and user-friendly:
- Control via a CA80 analyzer
- Alternatively via a time control function
- Installation compatible with existing holders
- Cleaning and maintenance: Replacement of pump hoses and filter without using tools
- Flexible:
- Modular filter system
- Accessories for a range of installation conditions
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. An optional cleaning valve enables backflushing of the filter unit with
compressed air.
