PSS Meeting Minutes

Spring 2009 Minutes

03.13.09

Working Group: 1

Accomplishments

• We analyzed the data collected in last weeks experiments
• Determined we had many errors in our system and a few calculation errors.

• incorrect peristaltic pump tube
• error in floc blanket height formation due to bubbles in the solenoid valve
• error in our calculation of Vc values

• Fixed these error successfully ran another prelimary run with the correct values and tested flow rates.

• Measured the floc blanket formation rate with the use of the mesh.

Metrics

• Failure in the 9.5 mm diameter tubes, but at very high Vc values.
• Floc blanket formation rate without the use of a mesh.

Outcomes

• We have fixed the problems that resulted in the unfavorable data and now have better results.

Issues

• We need to order the next three sizes of tubes.
• Continue research over break

Any Overall Team Comments:

We are all delving deeper into the research topic.
