How to Turn Sea Water Into Fresh Water Without Pollution

[dexter]

Enter the Solar Dome, a new desalination system built on existing technology. It’s supposed to be a low-cost, efficient, and carbon-neutral way of turning saltwater into freshwater. With water scarcity already threatening the Middle East, Saudi Arabia is the world leader in desalination, but the process does pose problems. We take a closer look at the environmental costs of desalination, and how new innovation like the Solar Dome is trying to tackle these issues.

According to this video, they have solved one of the two big problems with desalination. They have found a way to heat up the seawater using solar energy, rather than dirty fossil fuel energy. That is a big win, though hardly ground-breaking.

The other problem, is what to do with the brine by-product. They have not found an environmentally sustainable solution yet. But I think over time, they will figure out ways to breakdown and process the brine, to put the chemicals in it to good use. When that happens, we will truly solve the world's fresh water problem.

Can't then continue to dehydrate the brine, extract all the moisture, until you are only left is mineral deposits, and then take the mineral deposits and bury them deep underground in basically an artificial salt mines(who usually are a natural phenomena in similar processes via Evaporite formations).

Spain has developed Similar system. I am sure you can a video for it on YouTube.
