Water Purification by Ozone

Abstract

IN Engineering of January 4, Mr. T. Rich gives an account of the development of the treatment of water by ozone which has resulted from the researches made by P. Otto in 1898 in connexion with his thesis for a doctor's degree at the Sorbonne. When Dr. Otto was carrying out his experiments, the question of potable water supplies in France was becoming a matter of concern, and, encouraged by Pasteur, he took up the design of ozone water-sterilisation apparatus for outputs varying from that through a single tap to that required for large cities. One of the first important installations laid down to his designs was that for Nice, and since this was constructed many other places on the Riviera have followed the example of Nice, owing to serious outbreaks of typhoid. In 1932, the scientific commission for the study and control of the water supply of Paris decided to supersede the use of chlorine by the use of ozone for treating water taken from the Seine and the Marne, while quite recently an important ozone-sterilisation plant has been put into commission for the water supply of Nancy, a manufacturing city of 120,000 inhabitants. There are other plants in operation in Belgium, Italy, Rumania and on the Congo, and the system has been applied to the water supply of large passenger vessels. The principal apparatus in a plant is the electrically-worked Otto ozone generator, and of this Mr. Rich gives a full description.
