By running the ramp state function on different tube settler diameters, we hope to further develop the relationship between plate settler size and floc roll up.

Experiment 1: Ramp State with 9.5 mm Plate Settler Tube Diameter
...
The very clear spike in the data represents the point at which the floc particles began to roll up the tube settler, which was confirmed visually in the experimental apparatus. The velocity represents the critical velocity. At a certain velocity, the turbidity stabilizes, and stops increasing. This is because at a certain point, the number of flocs rolling up in the settler cannot increase anymore, therefore the turbidity cannot increase anymore. Given the current data that has been collected, we are not sure if this curve accurately represents how the turbidity should change during the ramp state function. Futher experiments are being run to confirm this.
