Abstract: Process for treating, especially waters to be made drinkable, with ozone in a reactor (2), especially with a bubble column, in which ozone is generated (in 1) in a gas enriched in oxygen containing at least 70% of oxygen by volume, to produce an ozonised gas containing more than 2%, especially from 2% to 20%, of ozone by weight, in which the said ozonised gas is diluted by means of a secondary fluid and the treatment is carried out by means of the diluted ozonised gas.Another subject of the invention is a plant for the use of the process according to the invention, comprising an ozoniser (1) generating an ozonised gas, at least one reactor (2) for treatment with ozone, and a supply pipe (3) connecting the outlet of the ozoniser with the inlet of the reactor, in which means (4, 5; 15, 16), for injecting a secondary fluid into the said supply pipe (3), are additionally provided.

Abstract: Device for supplying power from a three-phase network to an ozonizer comprising at least two discharge elements (3, 4) having a capacitive character, and comprising two single-phase step-up transformers (1, 2) having air gaps connected in a SCOTT circuit and connected between the three-phase network and said discharge elements (3, 4). The device further comprises a three-phase transformer (8) whose secondary windings (5, 6, 7) are connected between said single-phase transformers (1, 2) and the three-phase network and whose primary windings (9, 10, 11) are star-connected and connected to the three-phase network through a dimmer (12).

Abstract: The ozonization installation comprises a group of n ozonizers supplied with energy by a common source in a successive alternating voltage wave train mode, the application of the wave trains being controlled by a control device. The latter produces initiating signals which selectively enable the passage of the electric energy in the form of wave trains coming from the common source to the ozonizer. The installation comprises a servo system chain comprising devices for controlling the duration of the initiating signals by means of a set signal, having regard to the total ozonization produced by the n ozonizers. This duration corresponds to that of each successive wave train. Synchronization devices are provided for connecting the common energy source to solely one ozonizer at a time.

Abstract: The device comprises a fluid supply tube immersed in the liquid to be treated. There are disposed coaxially with this tube: an induction enclosure connected to the lower part of the tube and provided with induction orifices for the liquid and means defining a centrifugal pump. The pump is connected to the lower end of the induction enclosure and is adapted to draw in the liquid entering the enclosure in such manner that this liquid itself draws in the fluid supplied by the supply tube, to form in the enclosure an emulsion of the fluid in the liquid and to project this emulsion toward the surrounding liquid.Application in the treatment of drinking and waste waters.

Abstract: This device for measuring a physical operating characteristic of an ozonizer such as, for example, the ozonization power, the production of ozone or the concentration of ozone in the air, comprises a medium or high-frequency sensor placed in the ozonization zone of the ozonizer and an electronic processing circuit which delivers a signal which is an image of the energy received by the sensor. The sensor detects the medium or high-frequency energy produced in the ozonizer and produces a signal which is an image of one of the aforementioned physical characteristics owing to the fact that the curves of these characteristics are colinear with those of the medium and high-frequency energy components.
