Subteam Leader: Steve Mitchell

Number of team members needed: 3

Important team member skills:

Challenges

CDC

• Work with the team Honduras to evaluate the current linear CDCs at the Tamara and Cuatro Comunidades.
• Need to make the non linear mathCAd file more robust.
  • Incorporate how long tubing will need to be.
• Figure out how the non linear CDC will fit into the overall plant design.
  • Consider connecting two different tubing sizes to accommodate for the distance the flow control module and the stock tank.
• Extend the design to work for a large flow rate range.
• Run experiments to evaluate the materials being used i.e. flexibility of the tubing.
• Test the flow ranges with varying tube lengths.

Rapid Mixer

• Modify the rapid mix mathCAD so that the flocculator first section baffle spacing is no longer a constraint on the orifice collector channel width. In other words modify the code so that an aspect ratio (channel width/water depth) is specified rather a fixed depth.
