After this first task, our team moved on to our first main challenge (see challenge 2 listed). With the experiment group setting up the apparatus and running the experiments, I was assigned to process the data retrieved from each experiment through Mathcad and analyze the overall result. In the beginning, Laura and I narrowed down the alum dosage range based on the information given from the datalog. However, realizing that our approximations and speculations did not have a firm basis, rather than reading the datalogs ourselves, we changed our method of analysis to be based on the graphs from Mathcad. With each alum dosage, the experiment team varied the flocculator length. And with each set of data I processed through Mathcad, I documented patterns, discontinuities, and any particular trends that needed to be noted. With the Mathcad code modified by Sophie, I was also able to find the overall mean residual turbidity which drew a better overall summary of the experiment.
