Question by Setuch: What do water desalinating plants dilute brine with before returning it back to the ocean?

I read in an article that it takes two gallons of sea water to make one gallon of fresh water. My question is the left over water or brine is twice as salty as regular sea water. Plants say the dilute before returning it back to the ocean. My question is, dilute it with what? If obtaining fresh water is the goal, are they just taking that fresh water back and mixing it with the brine?

No, the desalinating plants will dilute the brine with more salt water because the brine is sometime more salt than water and hard to pass thru the pipes back to the ocean. Hope this clears up the confusion.
