Concentration measurement during sludge thickening

Measuring total solids 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
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, therefore unaffected by impurities
