This set of experiments attempts to replicate the grain size research performed with the previous experimental setup. Additionally, the effectiveness of each of the components in the setup will be assessed with respect to theoretical expectations. Theoretically, it is expected that the aerator under 2 atm of pressure will be able to supersaturate the water with 18 ml/L of dissolved gas. With the current aerator, a major assumption made is that the dissolved gas concentration equilibrates with the pressure in the aerator, sending water with 18 ml/L of dissolved gas through the sand filter.
