Short summary

Our work investigates the settling behaviour of natural granules applied in drinking water treatment plants. We show that these natural granules have a tendency to show a considerably large deviation in terms of their settling velocity; this is contrary to what many velocity prediction models assume. In the current work, we present and discuss the factors which contribute to the observed deviation in drag and settling velocity. It connects full-scale operations and research.
