. . . to make use of the u n i q u e a d v a n t a g e s of WELSBACH OZONE . . . and, if you are faced with an oxidation problem, it may well pay you to investigate the potential value of Welsbach "Tonnage" Ozone in your process. It's a new approach —a new and better solution to your oxidation problems. Ozone has always been regarded as a powerful oxidizing agent but there were problems—availability and dependability. Now those problems have been answered— with low-cost Tonnage Ozone, produced where it is u s e d . . . by dependable Welsbach Ozonators. Just consider these unique advantages— advantages which only Welsbach Ozone can offer! 1. N o procurement problems. N o freight, storage or materials handling expense. Welsbach Ozone is generated where it is used. 2. Fully automatic for continuous processings—maintenance costs are negligible. And since the only raw materials needed are electricity and air or oxygen, operating costs are constant and predictable. 3. Inorganic reaction with ozone is quantitative and instantaneous. And, since only oxygen is added, no post-oxidative cleanup is needed. VOLUME
