During Experiment 1, the following capture velocities were used: 5 m/day, 10 m/day, 15 m/day and 20 m/day (convert to mm/s)0.058 mm/s, 0.116 mm/s, 0.174 mm/s and 0.231 mm/s. This experiment was set on low floc blanket formation.

As expected, the effluent turbidity is much higher than that of the control experiment. The presence of saturated water in the influent has a negative effect on the effluent turbidity. In order to quantitatively examine the performance of the experiment with saturated water, data from the control ramp experiment was referenced. The average difference in error between the results was found to be 3.857 NTU. (What error and which results are you referring to on the graph? You can report standard deviation or relative standard deviation, but if you want to do this, I would suggest adding error bars for each point on the graph), with the effluent turbidity of the saturated water experiment generally higher in all cases than that of the control experiment. The bubbles released as a result of a pressure drop in the system disturbed floc formation, allowing less floc particles to settle and more, smaller, lighter particles to leave with the effluent. (Note floc break-up as a cause since you noted cloudy water from observation before)This is supported by the perviously noted observation that the floc blanket appeared cloudy.
