Floating Floc Meeting Minutes

Spring 2009 Minutes

March 6, 2009

Working Group: Bubbles

Accomplishments

• Wrote meeting
• Collected data

Metrics

• Ran several experiments simulating the different stages in the pipe leading to the grit chamber and the grit chamber
• Spoke with Monroe
• Spoke with Paul

Outcomes

• Found that DO probe is working properly
• Found that cracks in the lid aren't a problem.

Issues

• Dissolved Oxygen probe possibly malfunctioning
• Data collected doesn't make sense according initial theory

Working Group: Sand Filter

Accomplishments

• Acquired concrete data on the performance of the device
• Began altering sand depths in column and observing the effects on bubble formation

Metrics

• At 200mL/min, the column reaches its optimum extraction of air after 20 minutes
• Ran tests at different flow rates for ten minute intervals; found that the higher the flow rate, the more bubble extraction there was, which means that more dissolved oxygen was extracted

Outcomes

• Obtained more data
• Spoke to Monroe about getting more supplies to improve the setup

Issues

• Obtaining and installing a new DO probe
• Redesigning setup to improve quality of data; installing a pressure probe on top of the bubble chamber and finding a method to automatically remove air from the bubble chamber between runs
