So it deionizes the water too? Wow. If this technology does the same, doesn't that imply we'd need to supply people using this as a source of water with electrolytes and minerals for the water?
Mineralizing water is pretty straight forward, treating it to safe drinking levels is much more complex. So if you simplfy 80% of the water treatment facility's job, you can often process significantly more water through it at the same cost.
How is it different from desalination where you add some of the salt back in because the water is too pure?
I often wonder if this matters anymore, since food has a high amount of salt, and minerals.
The food in developing countries doesn't necessarily.
