Challenges for Fall 2009 and Beyond
Current Subteam Leader: Rachel Philipson
Number of team members needed: 3-4
Important team member skills:
- Fluid Dynamics Background
- Self-motivated
- Curious student
- Eager to learn
Challenges
- Develop a way to theoretically model and calculate the particle size that will roll up the tube settler at a given flow rate and spacing
- Improve model of critical velocity with respect to floc roll-up with Matt and Monroe
- Run experiments to test floc roll-up utilizing ramp function and attempting to visualize failure (flow rate/critical velocity at which a majority of flocs begin to roll-up)
- Continue to investigate the effects of the velocity gradient in the tube settler by varying the floc density and plate settler spacing (change alum dose, change influent turbidity, add NOM)
- 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
