Summary (AI generated)

Track B in the competition focuses on novel membrane materials for treating seawater to potable water quality using reverse osmosis membranes. The Winning Team will need to demonstrate an operational lifetime of at least 10 years. Teams will receive additional information on how to test for this capability.

The primary goals of the competition include treating seawater, meeting WHO standards for drinking water quality, and ensuring no harmful by-products with flat sheet membrane technology. Teams must also develop a scalability plan considering salt rejection percentage and create a Safety Data Sheet.

There are also bonus goals outlined in the competition guidelines for teams to explore.
