I

the

Spring 2008 Final Report
In the second half of the semester, the team had a very good sense of direction and the entire team functioned as one unit. I was involved in every stage of the design and construction of the FCM, flocculator and sedimentation tank. The team collaborated with Paul Charles of the Civil and Environmental Engineering machine shop to accomplish the construction tasks. The team built two plants, one of which was sent with the team to meet the Honduran minister in Washington D.C.
After the plants were made, I set up one plant in the lab with pumps, stirrers and turbidity meter to create the experimental setup. I also programmed Process Controller to run the experiments automatically. The results and calculations that followed gave us new insights on the demo plant, for example the fact that the vertical sections of the flocculator contribute very significantly to flocculation, despite previous believe that they were "wasted space". The results are reported on the Wiki as well as during the final presentation.
