- the present invention as shown in FIGS. 1 and 2 relates to a device or installation for treating a liquid, preferably aqueous medium (possibly containing undifferentiated cells or microorganisms), characterized in that it comprises, preferably communicating with a "reservoir" 6 of the liquid medium to be treated, a compartment 2, preferably of cylindrical shape or of square section, said compartment 2 comprising (along its wall) one or more emitters 1 of high ultrasound frequencies 4 emitted towards the interior of compartment 2 (preferably towards the center of this compartment 2), and one or more emitters 3 of gas microbubbles 5 arranged so as to ensure the emission of gas microbubbles 5 in the ultrasonic field 4 emitted in compartment 2.
- microbubbles means gas bubbles having an average diameter of less than 1 mm, preferably less than or equal to 50 ⁇ m, more particularly less than 30 ⁇ m.
- undifferentiated cells means cells having a hyperpoliferative effect such as tumor cells, bone marrow cells or totipotent cells, in particular algae cells, etc.
- micro-organisms in a liquid medium that is to be treated, all pathogenic or non-pathogenic organisms that can cause discomfort to humans, animals or the transport and storage facilities liquid media.
- microorganisms can be bacteria, viruses or algae.
- the definition of these microorganisms includes single and multicellular beings, in particular algae, which may be present in different liquid, preferably aqueous, media such as swimming pools, water tanks, aquariums, industrial cooling circuits. such as cooling towers, etc.
- liquid medium is also understood to mean physiological fluids which can be administered to humans or animals, or extracted from humans or animals and reinjected therein after treatment (ex vivo treatment of physiological fluids such as as blood, serum, cerebrospinal fluid, etc.), as described in American patent US-5401237 incorporated here by reference.
- "High frequencies” means frequencies between 100 kHz and several MHz.
- the high frequencies used are between 200 kHz and 10 MHz.
- said emitter 3 of gas microbubbles 5 is disposed at the base 11 of compartment 2, that is to say in the lower part of compartment 2, so that the microbubbles move by natural ascent or entrainment gas in the liquid stream.
- the gas microbubbles are microbubbles of air, ozone or oxygen.
- said microorganisms appear to be eliminated by the production in their environment of radicals of the H-, -OH and HOO- type also capable of forming H 2 0, this molecule and / or these radicals being toxic for these microorganisms and thus causing their inactivation and / or their destruction.
- the species created would result from reactions of high frequency ultrasound on the water molecule which could cause (especially in the presence of oxygen) the following reactions:
- the energy required to produce the toxic species is reduced if one works in the presence of these microbubbles. Indeed, it would seem that the injection of microbubbles in the ultrasound field causes an increase in the phenomenon of sonoluminescence, by the superimposition of the microbubbles on the cavitation bubbles caused by ultrasound, which seems to multiply the number of excited and toxic species. .
- This phenomenon is accentuated by the fragmentation of the microbubbles 5 created when they pass through the ultrasonic field 4, in particular when the device comprises several successive emitters along the wall of the compartment 2, which ensure greater fragmentation of the microbubbles and this , gradually.
- Figures 3 and 4 show a count of selenastrum capricornutu algae. It is observed that these algae placed in optimal culture conditions see their recovery threshold inhibited when they are treated with the device of the invention (with injection of microbubbles (Figure 3) and without injection of microbubbles ( Figure 4)). For a given ultrasonic power, the effectiveness of the treatment is proportional to the residence time in the compartment, and therefore inversely proportional to the flow rate.
- Figure 5 demonstrates, compared to a reference blank (treated under all conditions of concentration, flow, temperature and bubbling equal but without ultrasound), the effect of ultrasound. It is observed that a treatment by ultrasound but without the injection of microbubbles does not cause growth inhibition or reduction in the number of algae in the liquid medium.
- the device has the advantage that there is no need to dedicate ultrasound in particular areas, since it is found that the treatment system works by diffusion of the products formed in situ (for example radicals and H 0 2 formed) to the reservoir 6 of aqueous medium to be treated.
- the products formed in situ for example radicals and H 0 2 formed
- the ultrasonic transmitter 1 of the device of the invention is oriented so as not to cause standing wave phenomena, that is to say it is oriented obliquely to the axis 9 of compartment 2 (acute angle not perpendicular to this axis 9) and with respect to the flow of liquid and the flow of microbubbles 5 (see FIG. 2).
- This characteristic allows all the microbubbles 5 in compartment 2 to be treated in a statistically identical manner, without creating stationary zones in said compartment 2.
- the device also comprises a light emitter 12 towards the inside of the compartment 2 in the ultrasonic field 4, that is to say an emitter of electromagnetic radiation, the majority of which of the frequency is in the visible.
- a light emitter 12 towards the inside of the compartment 2 in the ultrasonic field 4, that is to say an emitter of electromagnetic radiation, the majority of which of the frequency is in the visible.
- electromagnetic radiation some of which frequencies correspond to ultraviolet radiation (UVA, UVB or UVC type ) or other types of energy emissions such as infrared, laser, microwave, etc.
- UVA, UVB or UVC type ultraviolet radiation
- the Inventors unexpectedly observed that a treatment comprising the emission of microbubbles in the combined fields of ultrasound and light radiation, was particularly effective in obtaining an inactivation and elimination of the microorganisms, in particular algae, present in the liquid medium.
- the phenomenon of sonoluminescence can favor the production of extremely active oxygen species such as the superoxide radical or oxygen of the singlet type, which are responsible for a whole series of
- singlet oxygen is to oxidize the various components of cells which are proteins, lipids, amino acids and nucleotides.
- a photosensitizing agent it is not always necessary to add a photosensitizing agent to the medium to be treated.

- Such a means of electromagnetic treatment of the aqueous medium allows, when said aqueous medium is subjected to the action of a field created between at least two transfer means (so as to modify the nucleation and / or the formation and / or the growth of crystals, in particular calcium carbonate), at least one of said transfer means receiving substantially rectangular electrical signals comprising a first phase in which the signal is close to a lower level and a second phase in which the signal is near a higher level, said signals having, when they are close to the lower level or the higher level, a series of damped variations.
- the signals correspond to the superposition of a rectangular wave of frequency less than 100,000 Hz, preferably between 1000 and 30,000 Hz, and of a damped sine wave of frequency less than 100,000 Hz, preferably between 1 MHz and 15 MHz, and the damping of the sine wave is such that after 5 periods of said wave, the amplitude of the variation is less than 10% of that of the initial variation.
- the latter for each phase of the rectangular wave, the latter is associated with a single damped sine wave, the frequency of the damped wave being greater than that of the rectangular wave and the damped wave being emitted for each phase of the rectangular wave, the life time of the damped wave being between 10 ns and 500 ⁇ s, preferably between 100 ns AND 100 ⁇ s.
- the potential difference between the lower level and the upper level of the rectangular wave is between 5 and 200 V, preferably between 12 and 60 V

- said salts consist of calcium carbonate present in the aqueous medium, which can be provided via a connection of the aqueous medium to water from the collection and distribution network or by adding said salts to the liquid medium.
- This large quantity of salts present in the aqueous medium can also be obtained by partial evaporation of the water, this phenomenon being particularly important in the cooling towers.
- the liquid medium can also comprise a supersaturation with other salts, such as phosphates or sulfates of alkali or alkaline earth metals, etc.
- Such a device makes it possible to develop anti-scale systems, to produce water supersaturated with salts, to cause biotoxic effects on certain microorganisms due to the presence of water supersaturated with certain salts, etc.
