If we conclude from laboratory tests that the foam material provides adequate filtration, it will be necessary to test the effects of natural organic matter on the foam material.
Foam Filtration Unit Design
This filtration unit design should be optimized according to the required surface area and filtration velocity parameters determined through previous laboratory experiments. In addition, it should minimize the required plan area, as well as maximize the ease of maintenance for the operator.

An alternative to using the foam simply as a flat sheet which water is filtered through is to design a hybrid upflow filter, which uses small pieces of the foam as the filtering material, as opposed to the traditional upflow sand filter. This idea is based on the technique outlined in this article, Water Filtration- Advantages of Fabric Media
