Subteam Leader:

• Tanya or Ling
• One can lead the physical modeling (Tanya) one the computer modeling (Ling)

Number of team members needed:

• 4-6 members

Important team member skills:

• Process Controller (can be trained)
• Microsoft Excel
• Mathcad

Challenges

• Accurately measure the flow rate of water through the sand bed for different sand grain sizes. This should be expressed as an upward velocity.
• Determine how this change in flow rate impacts the saturation of water leaving the bubbler (because you are changing the residence time in it)
• Build a taller supersaturator with a much longer residence time to ensure that the supersaturator reaches equilibrium over the wide range of flows needed.
• Accurately measuring the total amount of gas in the influent and the effluent
• Mathcad modeling of system (sand grain sizes, flow rates, bed depth, and expansion) relationship between bed expansion, sand grain size, flow rate, depth of sand, tank cross sectional area.
