In order to obtain conditions that better resemble those of an AguaClara plant, an alum dosing system and a rapid mix tube were added to our experimental setup. Ideally, these slightly larger and "stickier" particles are more likely to be trapped in the foam resulting, in a lower effluent turbidity.

In order to optimize the plan area required for a filtration unit, we would like to be able to utilize horizontal filtration, in which raw water would flow horizontally through a vertically positioned filter. Therefore, a A series of experiments were run to determine if this would be possible.
