Use of Ozone in Germany

Use of Ozone in Germany

Ozone works for the sterilization of drinking water have been erected in the following European cities: Wiesbaden, Paderhorn. Hermannstadt and Chemnitz, in Germany; Paris, Nice, Chartres and Dinard, in France; Florence, in Italy, and St. Petersburg, in Russia. Eminent authorities agree that the plants in those cities are working satisfactorily. The process of ozonization effects a complete destruction of all bacteria of typhoid cholera, and dysentery that may be contained in the water. At the same time it is claimed that the number of so-called innocuous bacteria in the water is considerably diminished. The ozonization process may also be used on a small scale where sterilized or chemically pure water is desired. Portable apparatus is made in Berlin that can be used for the sterilization of drinking water intended for soldiers while in the field. Machines are also constructed for the ozonization of water in ice plants, in breweries, on board ship, or for any other purpose for which a limited amount of pure water may be demanded. A representative of a large concern manufacturing ozone apparatus claims that under ordinary conditions the approximate cost of sterilizing water on an extensive scale is about one-fourth cent per cubic yard. This estimate, however, refers only to the cost of operation after the plant has been installed. Experience up to the present time has demonstrated that the cost of ozone sterilization, inclusive of the preliminary filtration, is 1.6 to 1,8 pfennigs per cubic meter (about ¼ cent per cubic yard), of which amount the ozonization process itself costs the city approximately onehalf.
