The whole point of the article is that this membrane has about 1000x higher flow rate than RO filters.

I still am not an expert, but the way I understand this is that, at say 30 bar, this membrane would produce 1000 times the amount of desalinated water as a conventional system, not that it would produce 100 times more at 3 bar or 10 times more at 0.3 bar than conventional ones at 30 bar.
