What do you do with all the leftover toxic brine?
Presumably it's toxic mostly because of the concentration of salt.
If it can't be used—and up north salt is used in winter for roads—it can be cleaned a bit, diluted with more seawater and discharged back into the ocean.
((the brine of 1 mass unit of seawater that's been desalinated) + 20 units of regular seawater) ÷ 20 = 20 units of 5% saltier seawater discharged
You make it sound so safe and easy. It isn't.

What is their ratios-of-brine to seawater do they use?
It's nice that you think you, without any experience in the matter, can solve problems with desalination that engineers in the field can't, but I doubt you are actually able to.
My question isn't totally rhetorical: I'm but an pseudonymous person on the internet.
Also, I don't think it's an engineering problem as much as a political one.
