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
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
