This semester, I am working on the foam filtration team. We are currently preparing our experimental apparatus to run an experiment to determine the head loss across the foam column both with clean water running through it and when the foam fails and collapses due to particle buildup on the top layer. Results were collected for both of these experiments, and will be used to help design the point of use filter unit. Additionally, we have begun experimentation with layering foam porosities in order to find the optimal layering that will increase filter performance. Additionally, the foam filtration team is working on designing a point of use foam filtration unit that will be submitted the the EPA P3 competition this semester.constructed in future semesters. Several different situations in which the filter could be used were analyzed, and different designs were considered for each situation. I have also worked on the EPA P3 phase 1 application for the foam filtration team, which included a written proposal and other forms.
Spring 2011 Contributions
During Spring 2011, I am again the subteam leader of the Foam filtration team. This semester the team is divided into two parts: design and research. The design team has been focusing on designing and constructing the prototype for the POU foam filtration unit. The majority of the work thus far has been to determine the best way to dose the influent water with alum. Experimental trials this semester have been focused on the trials with varying influent turbidities to determine the optimal range under which the filter can operate. Additionally, I have been working on a paper about the optimization and characterization of foam filtration and have been running individual experiments to fill in gaps in the paper.
