Does it come with or without micro plastics?
It will certainly comes with a preposterous amount of salt to deal with. That's a critical limiting factor with desalination.
I thought the salt level in the input rises. So you could cycle the input with fresh salt water and pump the higher salt content stuff back to sea.
