We based our initial design on empirical granular filtration equations from existing literature on granular filtration. A bench-scale model of our system was built and tested to observe the discrepancy between the actual and the calculated fluidization velocity required to achieve a target bed expansion. We noted an increasing difference between those two sets of values that prompted us to hypothesize that, if we were to base our design on these empirical equations, we need to implement a significant safety factor. Further experiments are needed before we can conclude whether or not our design is feasible.
