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 the 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.

M During the first stage, we conducted a literature and online review of existing filtration technology and research. We must determine 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. We then developed a MATHCAD file to generate filtration design parameters given state inputs. We then conducted bench scale experimentation of design parameters produced from the MATHCAD file.Click here for the Synopsis of literature and online review of existing filtration technology and research.

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