    Treatment of mineral water is restricted to removal of unstable elements such as iron and sulfur compounds. Treatment for such minerals may extend only to filtration or decanting with oxygenation. Free carbon dioxide may be removed only by physical methods, and the regulations for introduction (or reintroduction) of CO 2 are strictly defined ...

    A 1965 report suggested synthesizing methanol from carbon dioxide in air using nuclear power for a mobile fuel depot. [62] Shipboard production of synthetic fuel using nuclear power was studied in 1977 and 1995. [63] [64] [65] A 1984 report studied the recovery of carbon dioxide from fossil fuel plants. [66]

    en.wikipedia.org/wiki/Water_softening

    Rain water contains dissolved carbon dioxide taken from the atmosphere. Some of the dissolved carbon dioxide reacts with the water to form carbonic acid, which remains in solution. Minerals containing calcium and magnesium form soluble bicarbonates when exposed to carbonic acid. Water containing these minerals is known as "hard water".
