What is it about?

The hindered settling function in decanter centrifuge has been in situ measured by periodic segmentation technique implemented in wireless electrical resistance detector (psWERD). The proposed technique offers the in situ measurement in the decanter centrifuge for real hindered settling function based on the distribution of particles volume fraction during the centrifugation.

Why is it important?

The significance of psWERD is that we introduce the in situ measurement technique to enhance the approaches of hindered settling function calculation, particularly, in decanter centrifuge. Conventionally, the calculation of hindered settling function is conducted by Sigma theory, which relies on experimental data after the centrifugation. By using psWERD, the real-time and in situ experimental data is used and processed to obtain the in situ hindered settling function which leads to the direct evaluation of the separation performances of the decanter centrifuge.


I do hope that this proposed technique can contribute to the powder technology society, particularly, for particle-liquid separation machinery such as decanter centrifuge. Moreover, psWERD has been compared to previous works and showed a good agreement. Therefore, we hope that this technique could broaden the measurement technique of hindered settling function.
