The results for our research semester are that no concrete conclusions could be made towards the Floc Breakup theory because the new turbidmeter system still needs a lot of work and there are still many things we do not completely understand about SWaT. The research this semester has shown us that there are still improvements that need to be made to SWaT. Unfortunately, all the tests we have run so far are proving SWaT to be a worse residual turbidity measurement system than FReTA was. The NTU readings using SWaT were significantly higher than the NTU readings for FReTA at the same PACl dosage concentrations. Nonetheless, SWaT has been incorporated into the Laminar Tube Flocculator apparatus and Process Controller has been updated to the correct states.
Fall 2014 Semester Contributions
Semester Goals
The Laminar Tube Flocculator Team hopes to build off of the Summer 2014 Research Team's work on testing Floc Breakup Theory and make a final conclusion as to whether or not breaking up flocs in the midst of the flocculation process improves flocculator performance. Goals for this semester include running experiments using varying PACl dosages and finding an optimal PACl dosage that results in the best flocculation performance. Hopefully by the end of the semester, clearer correlations can be drawn from the experimental data and conclusions regarding Karen Swetland's Floc Breakup Theory can be finalized.
