Research will focus on developing a point of use unit that uses foam filtration. Additional experiments must be conducted, including determining the head loss across the foam, the head loss at which the foam fails (collapses), the optimal layering of foam porosities and the range of influent turbidities over which the filter performs successfully.

Foam Filtration Future Research
After laboratory tests on the filtering capacity of the polyurethane foam material are concluded, we will continue to explore different research areas. This will include the effectiveness of an aluminum hydroxide wash to decrease the ripening time of the foam, the effects of natural organic matter on the foam material and the most efficient way to clean the foam material.
