Our attempt to validate our clear well design consisted of three stages: 1) review of existing filtration/backwash technology and research, 2) development of a MATHCAD file that can generate backwash and filtration design parameters for both an actual AguaClara plant and a bench-scale or pilot plant model of the plant for testing and 3) experiments of bench-scale or pilot plant model to confirm design success.
During the first stage, we conducted a literature and online review of existing filtration technology and research. We determined the flow rate needed to sufficiently expand and clean the sand filter bed. This will help us determine how high the clear well needs to be above the filter, how large the flow pipes should be, and how much water should be in the clear well.

Using what we learned from our research, we developed a MATHCAD file, which generated design parameters for our filtration/backwash system when provided with plant flow rate and properties of the granular filter. The MathCAD file contains Besides being the basics important parameters for the final design of the filtration and backwash system for an actual AguaClara plant this program would also generate scaled down parameters and for bench-scale or pilot plant-scale testing.
