Experiment 4: Alum dose = 15 mg/L
This is an underdose. These graphs show the effluent turbidity plotted against time for capture velocities of 0.058, 0.116, 0.174, and 0.231 mm/sec.
.
Figure 1: Effluent Turbidity vs. Time for Floc Blanket on low, alum dose = 15 mg/L
Figure 2: Effluent Turbidity vs. Time for Floc Blanket on high, alum dose = 15 mg/L
Conclusions
This unexpectedly performed well, excpet the floc blanket took a long time to form
