Your FO membranes will foul very rapidly from the Exopolymeric substances given off by the algae. Rob accted for 20% flux reduction, but I think depending on the species, you might be seeing something more severe than that, particularly for algae that weeps oil, like Botryoccocus Braunii.

We have already done extensive cycling on the membranes. The algae forms a layer on top but it doesn't impact performance. We have cycled the membranes 30 times which is equivalent to 1 year of use in the ocean. We are repeating more tests, but these particular membranes have already been through some pretty severe testing required for spaceflight and other food processing applications. I'm not how you can make such statements without knowing what kind of materials that we are using.

In response to your other concern, we are not using Botryoccocus Braunii, it grows too slowly.

PM me. :)
