A range of depths will be explored to determine the relationship between bed depth and gas removal. Experiments have shown that increasing bed depth increases gas removal. Future experiments will explore the exact relationship to determine whether gas removal will increase with bed depth or whether gas removal levels off at some range of bed depth, etc.
Bed expansion (which depends on the flow rate of influent water)—The expansion of the sand bed affects its porosity, which affects the distance a gas molecule must diffuse to reach a surface, and also may affect aggregation of gas molecules to form larger bubbles. We would like to see the effects on gas removal using different expansions while holding other parameters constant.
