Spring Semester 2008 Research Goals
The team has discussed and agreed on several important goals to focus on for the Spring semester 2008:
- Analyze the data from the Fall Semester 2007 and make solid conclusions. The team will look into further analytical tools such as Excel, MatLab, and MathCAD to handle and display the data in a better, more user friendly format. The team last semester found that the current MathCAD file is hard to use, for example if the user wants to isolate one run in a series of iterated experiments or compare certain runs to each other on the same graph.
- Develop models to describe what is happening in the flocculator. The team will use this to determine what parameters are important in regulating the flocculation process.
- Literature research to compare research, to see if previous similar experiments have been conducted, or for inspiration for further experiments or data analysis.
- Find the relationship between G and Gθ. This is the ultimate goal that the team is trying to determine, it will take a combination of data analyses, modeling, and maybe more experimentation.
Ongoing Research - Spring 2008
- Developing analytical methods for understanding flocculation/settling data from our tube flocculator apparatus
- Augmenting sampling frequency and accuracy of our nephthelometric turbidimeters by accessing raw voltages directly from sensor
- Reevaluating the efficacy of tube flocculator setup & designing methods to eliminate sedimentation within flocculator and maintaining quiescent conditions in the settling volume
- Determining settling velocity and floc concentration using PIV.
- Writing tutorials on Process Controller.
Future Research - Beyond Spring 2008
- Using PIV to evaluate floc formation from previous experiments: varying alum dose and varying G in flocculator
- Once the new IR turbidimeter is up and running, re-run previous experiments from last semester and compare settling curves
- Develop Process Controller Tutorial and exercises for future team members
