I don't know any reverse osmosis makers that are anywhere near 1:1. Current RO systems are 9.5:1. Over 90% of the saltwater is rejected as brine.

These 1:1 are the best numbers for demineralizing sweet water - I assumed that salt water desalination had much different proportions, which also means, that the relative change in salt content is pretty small and consequently the impact of putting it back into the sea.
