Floating Flocs Meeting Minutes
Spring 2009 Minutes
April 24, 2009
Working Group: Sand Filter
Accomplishments
- Improved the setup by using larger tubing in order to accomodate the higher flow rates
- Implemented the aeration apparatus (bubble chamber) to supersaturate the water entering the sand filter column; automated the setup again
- Obtained a new, taller plastic column (to replace the broken glass column), pressure regulator, and flowmeter and implemented them into the setup
- Final Report Draft completed.
Metrics
- Ran the experiment with Sand 40 (0.42 - 0.59mm) again at the different expansion levels
- Measured the actual flow rate coming out of the bubble collector for each run
- Performed a sugar test for each run
- The new plastic column has a height of ~125cm and inner diameter of ~3cm. The top cap of the column has a 3/8" outlet and the bottom has 1/4" inlet.
Outcomes
- Sugar test still shows that there is a lot of dissolved oxygen present in the water
- Good results and graph for Sand 40
- Cannot run experiment with Glass Beads due to either pressure buildup or flow rate is too fast even with a flow rate of 0.2 mL/min on Process Controller
Issues
- Getting to new setup to work on its own so that it can run overnight
- Still need to collect data for Sand 30 and Sand 20
