Data Analysis on New Setup

Data Analysis on New Setup

The team has decided to proceed with experiments even though the recirculation problem has not been fixed. By conducting some test runs, we are hoping to get a better sense of how the new setup will improve the settling efficiency of tube flocculator.

Results and Discussions

Figure 1 illustrates the effect of different setups of tube flocculator. Using similar initial parameters, the new setup shows a faster drop than the previous setup. This could be an indicator that the new setup has more bigger flocs during the settling state than the previous one. Data smoothing is applied to eliminate fluctuation due to recirculation problem that previously indicated.

Figure 1 The data was smoothed using window average of 33.

The raw data is also normalized and Figure 2 indicates that the changing of setup does not have too much effect to the data.

Figure 2 The raw data was normalized.
