The previous team conclusion on this kind of experiment was that increased fluid shear not only decreased the average size and sedimentation velocity of flocs, but it resulted in higher residual turbidities as well. The results of Fall 2009 are consistent with the previous team results.
The goal of this experiment was not to analyze into depth the results but to replicate on of the experiment from Spring 2009 and understand the utilization of the data processor. The next set of experiments will analyze the evolution of the effluent turbidity with the alum dose and the length of the flocculatorProcess Controller
