Fall 2009 Contributions

I am on the Design team. I started off the semester working on the design of the horizontal flocculator. To understand how the algorithm works, I documented the design of the vertical flocculator and discussed some minor changes with Monroe, including lowering the height of the top baffles to half of the freeboard height in the flocculator to allow space for water to go if there is an overflow. I looked at what would be different for the horizontal flocculator and began to code the changes. I also discussed when the transition should occur vertical to flocculators, which is the flow rate that makes the horizontal flocculator the same height as the sedimentation tank. Once we learned that there needed to be design changes for Agalteca, however, I worked extensively on that, especially on the flocculator. We changed the energy dissipation rate to be even such that there were even baffle spacings. I also aided in determining the new design of the sedimentation tank with Monroe, Nicolas Pautassi, and Gonzalo Caprario. As AguaClara Team Leader, I have done a lot of organizational work including setting up the syllabus, sending out reminder emails, grading weekly minutes, and helping the Outreach team.

I have been doing a thorough review of the wiki and making any necessary updates.
