Floating Floc Meeting Minutes

Spring 2009 Minutes

March 27, 2009

Working Group: Bubbles

Accomplishments

• Teach in on March 25, 2009

Metrics

• Spoke with Monroe

Outcomes

• Considering alternative solutions to floating floc problem

Issues

• This method may not work

Working Group: Sand Filter

Accomplishments

• Completion of the Sand Filter Simulation Image for Teach in
• PowerPoint Presentation for Teach in on March 25, 2009

Metrics

• Conflicts within data may be a result of the order in which the depth of the sand is changed
• Spoke to Monroe

Outcomes

• Need to run the experiment at different flow rates. 
• For next week: Run experiments with different sand densities or diameters
• For next week: Run a sugar test to ensure our setup is truly stripping the dissolved oxygen out of the supersaturated water.

Issues

• There seem to be some bubble formation in the Flow accumulator when the depth of sand is changed. Possible solution is to let sand completely settle before running another experiment
