Final Experimental Design
Video of PEG trial with 20 cP solution
PEG trials were done similarly to water trials but no drop in concentration was recorded for a 20 cP solution.
Trials were then done in beakers using an air pump to sparge air and the probe to stir the solution.
Small beaker trials with 5 cP solutions showed promising results. Probe was able to record drop in concentration.
The promising results for the 5 cP solution in the small beaker led to a scaled-up trial in the large tank
PEG trial with 5 cP solution in large tank. Probe did not detect drop in concentration
Sodium sulfite was added as a powder for the trials in large tank. A spike solution with the sodium sulfite already dissolved in the PEG solution was then used in the trial instead of the powder to overcome the foam layer
