A new perspective on the modelling of settling behaviour in water resource recovery facilities is introduced. The ultimate goal is to describe in a unified way the processes taking place both in primary settling tanks (PSTs) and secondary settling tanks (SSTs) for a more detailed operation and control. First, experimental evidence is provided, pointing out distributed particle properties (such as size, shape, density, porosity, and flocculation state) as an important common source of distributed settling behaviour in different settling unit processes and throughout different settling regimes (discrete, hindered and compression settling).

- Advanced 1-D models for Secondary Settling Tanks (SSTs) consider various factors affecting the settling process, like hindered and compression settling, requiring careful selection and calibration of mathematical expressions.
- Evaluating existing hindered settling functions against long-term data reveals that traditional exponential models combine hindered and compression effects, making them inadequate for precise advanced modeling.
- A power-law function is identified as a more suitable option for accurately representing hindered settling velocity in advanced 1-D SST frameworks.
