Announcements
Class notes
Read through pages 341-355 of the notes and view the online narration below. Don't forget to complete the quiz in Canvas!
The main points of the lecture were
- Concentration Polarization in Filtration
- Membrane Sweeping for a Rotating Membrane
Goals:
After this class you should be able to:
- Understand why concentration polarization negatively affects filtration.
- Scale the transport equations to determine the rotational velocity necessary to mitigate buildup for rotating membrane systems.
Reading
- The class notes.
- BS&L 22.8-5
- The solution to the rotating plate problem from last year (problem 11-3)...
- The Wikipedia article on this flow field is also useful.
- A nice article from the Bruening group describing ion separations via membrane filtration is found here.
