Summer 2009 Semester Contributions

This semester, I am the leader of the Floating Floc research subteam. Thus far, the bulk of my responsibilities include training new members of the Floating Floc team, assembling and debugging the experimental setup to be used this summer with my teammates, and generally organizing/coordinating the summer plans of the floating floc team with team members in a way that is hopefully reasonable and beneficial to all. The Floating Floc team's summer plans can be viewed in the Summer 2009 detailed task list and research proposal which can be reached via the Floating Floc main page.

Currently, the bulk of the system has been debugged and is functionally up and running. Hopefully, we will be able to consistently run experiments, collect and analyze data. In the time we were unable to run experiments, the team and I focused on teach-ins and other assignments while trying to fix the setup. Additionally, we decided to begin performing literature searches earlier than originally planned.

Spring 2009 Semester Contributions

For the past semester, I have been working on the Dissolved Air Floation of Flocs team. Originally, I was involved with the Aeration subteam; however, with the dissolution of that group (due to the conclusion that the method was ineffective) I joined the Sand Filter team. The bulk of my work involved aiding in the assembling process and expansion of both setups. Post construction, my focus was mostly helping the team run experiments concerning gas removal from supersaturated water with both the aeration and the sand filter setup. When it was necessary to obtain a range of sand grain sizes for the sand filter, Haley and I spoke to Professor Stewart in the Geotechnical Department and I subsequently aided in sieving out a range of sizes. After data collection from both setups, I aided other team members with data analysis.

My wiki work this semester include drafting up an AutoCAD diagram of the aeration experimental setup that can be found in the Floating Floc Team's Detailed Task List. I've also made flow diagrams and other diagrams for the aeration method and helped to reformat the Floating Floc main page and most of the Aeration Method pages.

While the experimental setup was being constructed, I also performed literature searches in order to find relevant information regarding factors facilitating bubble formation in supersaturated water. The articles I have found are:

Effects of Dissolved Gas Supersaturation and Bubble Formation on Water Treatment Plant Performance by Paolo Scardina

The Fundamentals of Bubble Formation in Water Treatment by Paolo Scardina and Marc Edwards
