Sample preparation system PurCon®

WTW sample preparation PurCon®

The perfect online sample preparation - continuous, safe, low-maintenance. Yields samples free of suspended solids and bacteria

  • Continuous sample preparation
  • Suspended solids and bacteria-free permeate
  • Very low maintenance thanks to BubbleClean® self-cleaning system
  • Permeate for up to 3 analysis modules

In contrast to regular preparation procedures, e.g. the sedimentation, the PurCon® device continuously supplies samples that are free of suspended solids and bacteria. Thanks to the self-cleaning BubbleClean® procedure, this type of sample preparation is very low-maintenance.

The sample preparation system is suitable for all kinds of applications in the wastewater treatment industry, even for applications in biological cleaning levels with hard to sediment sludge portions. The sample preparation PurCon® is the ideal supplement for the TresCon® analysis system, as up to three online analysis modules can be supplied with permeate at the same time.

With typical applications in municipal wastewater treatment plants, e.g. in biology (3 – 6 g/l mud), a maintenance-free operation is possible for up to 6 months.
