After visiting Honduras, the apparatus designed in fall 2013 was implemented with mild success. The design met the desired constraint of 1 NTU however the filter was difficult to use, especially in cleaning. The Fall 2013 team designed the foam filtration unit to fit all into one 55 gallon drum. The apparatus consisted of two 23” disks: a roughing filter that used 30 ppi* foam and a finishing filter with 90 ppi foam. The filter unit was designed on the premise of providing water for a community of 100 families at approximately 1 L/s. The Spring 2014 team updated the apparatus for easy use and transport.

In order to clean this unit, a user-friendly simple pulley design with a hoist supporting approximately 500 pounds of concrete was implemented to compress the foam with a hard plastic plunging disk. A side drain was spin-welded to the drum to drain the dirty water that pooled on the surface. This was the beginning model for summer 2014. |
