Abstract
In order to move towards advanced 1-D models for secondary settling a more thorough understanding of compression is necessary. The inability of the current modelling frameworks to capture the variability in the compression phenomenon indicates that there is still something missing in the expression describing compressive settling. This can potentially be attributed to phenomena such as variations in the flocculation state and segregation of particles during settling which are not considered in the current modelling frameworks. In this work evidence is provided to support this hypothesis together with a brief overview of possible extensions/alternatives to the current modelling frameworks allowing for a changing flocculation state.
