Challenges

- To explore the effects of plate settler spacing on effluent turbidity when conditions are not ideal. Not ideal conditions may be characterized by low turbidity influent, organics in influent, or dramatically reduced alum dosage.
- Continue to improve model of critical velocity with respect to floc roll-up with Matt and Monroe, try to determine what consitutes failure in terms of floc roll up
- Run experiments to test floc roll-up utilizing ramp function for a variety of tube settler sizes and attempting to visualize failure (flow rate/critical velocity at which a majority of flocs begin to roll-up)
- Investigate ways to optimize plate settler performance given changes in influent properties such as natural organic matter, pH, and alkalinity on floc performance and plate settler performance
- Continue to investigate the filter foam
- Begin to write a paper on floc roll upTo further explore the impact of the floc blanket on sedimentation efficacy.
