Brine is just water plus the salt that was in the seawater before. You have to dilute it and spread it.

But, sufficiently diluted, it’s just seawater.

In a sense, it’s the same effect as water evaporating over the ocean: Water goes out and salt remains.

It's not as easy as 'dilute and spread' -- highly concentrated brine doesn't really mix readily (halocline effect) when released back into the sea.

Couldn’t there be some kind of dilution step in the plant, using pumps to mix it 1:10 with seawater?

After that, it’s just slightly more salty seawater.

[sithadmin]

Relatively small differences in dissolved salts are enough to cause halocline barriers that don't really mix well and still pose a hazard to local flora/fauna.

Technically uranium is in all kinds of soil in small amounts... turns out the poison is the dose.

It starts getting really expensive moving a lot of heavy brine and attempting to dilute it, especially when the amounts of water you'll need will create mountains of salt.

Is there a good way to dilute it without using water?

[saalweachter]

As long as you can dilute it with salt water (until it's not deadly) that shouldn't be a problem.
