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
• Recommending one team member who's sole responsibility is troubleshooting: This requires extensive knowledge of how process controller and the experimental apparatus work

Challenges

• 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 up
