Excerpt
Challenges:

  1. What limits the cleaning efficiency of the foam?

  2. Do oscillations while plunging enhance cleaning efficiency? (Preliminary evidence from El Carpintero, Honduras, suggests that oscillations improve cleaning.)

  3. Which sizes of foam and what depth of foam can be cleaned using the plunge method?

  4. Could a high flow rate be used to clean the foam?

Summary

Goals of the semester:

  • Create an efficient testing apparatus for foam back wash
  • Design a new testing method and standard for foam cleanliness
  • Figure out the parameters that most affect back washing the foam
  • Figure out if the foam used for filtering contains any harmful materials (Duke Foam Lab)
