As expected, the effluent turbidity is much higher than that of the control experiment. The presence of saturated water in the influent has a very clear negative effect on the effluent turbidity. 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. The occasional spikes in the data represent an air bubble floating up through the settler which creates a temporary spike in the turbidity.
