Data for: Removal of mineral colloids from water by oscillating flows and grouping
This video, filmed with Go-Pro Hero2, is an overview of the grouping process in a laboratory experiment conducted in a 2 Liter beaker with initial turbidity of 50 NTU. The time shown in the down right corner of the presentation is in minutes (high speed editing). The experiment consisted of 30 minutes of oscillations. The white sedimentation which accumulates in the bottom of the beaker are the aggregates which are formed and settle due to the oscillation process in distinct settling zones. The shape of "lungs" formed by the aggregates sedimentation is representative for all experiments.
