Use of Ozone in the Technology of Bottled Water

Sulphur, iron and manganese are easily oxidized by ozone and the iron and manganese hydroxides are removed by filtration. Arsenic is eliminated by coprecipitation with iron. Fluoride can be largely removed by filtration through alumina. Any off-taste, occasionally caused by natural organic substances, is prevented by the ozone treatment. Additionally, the possibility of sterilizing wine bottles with ozone-containing water, is shortly dealt with.
