52 videos calcite grains fluidised in water in an experimental setup using a Canon LEGRIA HF G25 camera. CaCO3 calcite pellets (1.4-1.7mm) and (0.8-0.9mm) in a D=57mm PVC transparent cylindrical column with water at 18 °C for various linear flow rates (flow from left to right). An advanced experimental study at the pilot plant at Waternet Amsterdam.

This research is part of the project “Hydraulic modelling of liquid-solid fluidisation in drinking water treatment processes” carried out by Waternet, Delft University of Technology. Financial support came from Waternet Drinking Water Production Department.
