Figure 1: Effluent Turbidity vs. Time, Floc Blanket on Low, Alum dose = 65 mg/L
An alum dose of 65 mg/L is considered to be an over dose. At this point in time, only the data for the Floc blanket on high has been collected.

Figure 2: Effluent Turbidity vs. Time, Flock Blanket on High, Alum dose = 65 mg/L
For the Floc Blanket at both the lower and higher levels, the capture velocity of .057 mm/s produces a lower effluent turbidity than the Vc = .116 mm/s, and Vc = .174 produces a higher effluent turbidity than Vc = .116 mm/s, which is expected. However, Vc = .231 mm/s produces a lower effluent turbidity than Vc = .174 mm/s. This is possibly because of particles rolling up the tube settler... FIX
