That’s not how it works. Think of this as what happens when you drop a couple of cubes of ice in a tub? The temperature of the tub doesn’t go down for sure like you said, but the water around the ice cubes will be very cold. That’s what happens when you release highly concentrated water in the sea, the marine life is decimated but overall the salinity of oceans doesn’t change.
Now you could argue you could dilute the release water, but then why desalinate?

- richk449 4y agoWhy would the salt be dumped back in the ocean? Wouldn’t it be sold to consumers?
- stametseater 4y agoThe "salt" is in the form of brine, it's a liquid and you'd need huge evaporation ponds to keep up with the outflow if you wanted to dry it all out to sell. If you put your desalination plant near urban areas, where the demand for fresh water is, then the land you'd need for evaporation ponds would be a lot more expensive, and I suspect the profit margins for salt are fairly tight (sea salt competes with salt mines where they just scoop the stuff right out of the ground.)
