Foam Filtration Unit Design
We are currently designing a foam filtration unit for four separate situations:
- A family of 7 to 10 people with access to a tap with untreated water. It is assumed that the family will use the filter for all of their water needs: drinking, cooking, cleaning and bathing
- A family of 7 to 10 people with no access to a tap. Since this family must carry all of their water to the filter, they will not use treated water for all of their needs. They will filter their drinking and cooking water, which will result in a decreased filtering capacity required for this design.
- An apartment complex with approximately 150 people with access to a tap. This design will be similar to the family unit with a tap, but the surface area of the filter will be larger to reflect the necessary increase in filter capacity.
- A village without a municipal water distribution system. These people would get water directly from a source. This filter will be brought to the water source used by the community and residents will all use the filter at the water source. Because people in such communities must carry their water from the source, the filter size will be designed to handle the drinking and cooking water needs of community residents.

Our designs use the 2.0 density foam, which is the sites version of the 90 ppi foam.
