I'm writing a story in a world very similar to our Earth, but with few differences. In this world, the "human" beings have to deal with the shortage of drinkable water. But they have plenty of distilled water available.
To keep a realistic background, are there (here) some plants or other forms of life that can enrich distilled water adding the required substances to make the water drinkable?
For example, I know that peas enrich the soil with nitrogen. So I wonder if there are other species that using the solar energy (or with some other external helps) release into the water the
nutrients minerals and salts useful for our life.
I'm thinking about a kind of hydroponics tanks where these plants grow and after some time you can drink the water.
