Spring 2014 Mid-Semester Contributions 

As this semester picks up, the team continue to update the foam filtration unit. Current tasks include: designing a side-valve that can go into the 55gallon drum without creating a path of least resistance for water to flow through, investigating materials for the compression unit that will not rust, designing an efficient compression unit that implements pulleys, and finding more suitable materials to construct the plunger such as stainless steel wire mesh or geomembranes. Once all the components are assembled, the whole unit will be tested in lab for varying turbidities with a fully designed LFOM and flow controller.  The goal is to create an easy to assemble and clean unit. 

Spring 2014 Contributions

This semester our main goal is to redesign the 55-gallon drum unit that went to Honduras. While the unit did work successfully, the cleaning procedure was extremely over-designed. A new cleaning technique that is both compact and easy to use will be designed and implemented this semester. Additionally, the unit should have components such as the LFOM, dose controller, and drainage pipes that are compact and can be easily set-up.
