Experiment 1: Effluent Turbidity v Time - High Floc Blanket Formation

During Experiment 1, the following velocities were used: 5 m/day, 10 m/day, 15 m/day and 20 m/day. This experiment was set on high floc blanket formation.

Conclusion

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 occasional spikes in the data represent an air bubble floating up through the settler which creates a temporary spike in the turbidity.
