Concentration measurement on primary and secondary sludge

To achieve a better rate of dewatering, a flocculating agent is added to the sludge during dewatering. Prior to addition, the solids content is determined by microwave measurement to not only optimise the dosing but also to monitor solid content in the feed to control for constant solids loading.

Technical Features

  • Reliable online concentration measurement
  • Representative output with microwave transmission measurement through entire pipe or through product stream.
  • No wear of components as with other technologies.
  • Precise measurement with only one calibration coefficient even with different sludges.
  • Automatic temperature compensation
  • Maintenance-free measuring system

 

Customer benefits

  • Reduce costs by optimising polymer and flocculant addition
  • Non-optical measurement, insensitive to contamination
