Foam Filtration

We are currently in the midst of ploughing through our task list. We have already tested the lifetime of the foam and compression/ decompression abilities. From our tests, we were able to conclude that the foam does not encounter too many problems with mechanical failure, however the structure upon which it sits requires an immense amount of work. There is a need for a more stable structure because of which we are looking into using circular, plastic drums; they would allow for a "tight seal" (between the foam and the filter wall), a sturdy base, and a filter that can visually display its contents. Also, it was discovered that the foam cannot decompress on its own and the string-method of decompressing the foam is extremely tedious, especially when only one of the filter columns is being compressed. The team will look into creating a single column filter system and implementing a mechanical arm to create a more efficient and user-friendly system.

Foam Filtration

We aim to determine a design in which cleaning and draining the filters is most efficient, the controller has the ability to turn individual filters on/ off, and a chemical doser is incorporated.  We will also try to establish some basic information by researching the lifetime of the foam filters, as well as, the level of turbidity that the foam filters can handle. We are hoping to improve the foam filtration system with the purpose of not only increasing its capacity/ variability, but also having it ready to go for implementation in Honduras this winter.
