Abstract: The invention relates to a method and a device for improving the biodegradability of an organic sludge. It comprises at least two treatment cycles each of a total duration of between around 8 s and around 20 s and each comprising a first step of producing a first hydrolysed sludge emulsion in a first, reduced zone, by injecting a gas into said reduced zone. a second step of abruptly expanding the emulsion in a second zone—the expansion zone—and a third step of recovering the emulsion via a third, restriction zone.

Abstract: The invention relates to a method and a device for continuously or semi-continuously treating/dehydrating organic sludge (1, 41, 69}, wherein a three-phase emulsion of air, solid matter and water is produced by injecting air (6, 47, 68) into the sludge, introducing a flocculant (13, 50, F) into said emulsion in order to create a floc (14, 51) and then degassing said floc at atmospheric pressure. The floc is degassed by soft impact of the floc on itself or on an energy absorbing shutter (39, C), braking the floc, and the floc matured in this way is recovered in a filtration and/or decanting device (56, 74).

Abstract: A method and a device for the continuous purification of a domestic or industrial water stream. After passing through a biological reactor to obtain a sludge of between 4 and 12 g/l of Dry Solids, the method involves feeding a series of chambers separated by restrictions at a flow rate q, injecting air into a second chamber at a flow rate Q>q, in order to obtain an emulsion, injecting a flocculant into a third chamber, and recovering the degassed emulsion in a drain pan. Flocculated and aerated sludge floats on top, such that the remaining liquid centrate has a Dry Solids content less than 100 mg/l and has a positive redox potential>50 mV and a value greater than 100 mV relative to the redox potential of the sludge at the inlet of the chambers, and is reinjected upstream from or into the biological reactor.

Abstract: The continuous treatment of a flow of organic liquid sludge is disclosed. Following the optional addition of granular mineral matter to the flow, the sludge is injected at a rate q into a column of air which is at overpressure relative to atmospheric pressure. The air column is circulating at a rate Q>5 q in a chamber extending over a specific length in order to create a fluidized bed, in which the sludge is aerolized, between air supply piping upstream of the sludge injection and an outlet reservoir downstream of the fluidized bed, the reservoir being substantially at atmospheric pressure. A flocculant is introduced continuously downstream of the chamber into the fluidized bed in order to aggregate the organic matter before the solid part obtained in this way is separated from the liquid part, the resulting solid part thus being deodorized.

Abstract: Treating an organic effluent is disclosed. The effluent is fed in a continuous flow at a rate q via a first chamber maintained at a first pressure and/or directly through a first narrowing to a second chamber or container maintained at a second medium pressure by the injection of air into the second chamber at a rate Q in order to obtain an emulsion in the second chamber. A head loss is generated in the emulsion optionally modified by a second and/or third narrowing or a feed valve for a third chamber maintained at a third pressure in the region immediately downstream of the second or third narrowing and/or valve. A flocculant is injected into the region of the third chamber. The emulsion at atmospheric pressure then being degasified and the emulsion thus degasified being recovered in a filtration or decanting device.

Abstract: The invention relates to a method and a device for anaerobic digestion from an organic liquid sludge (21), comprising, in a known manner, a step of hydrolysis/acidogenesis of the sludge in a digester (47, 100), a step of acetogenesis for producing acetate from the hydrolysed sludge and a step of methanogenesis from the acetates for producing methane. The method comprises an initial step of creating a hydrolysed sludge emulsion (23) obtained by means of the impact of the sludge with gas (27) injected into the sludge, then continuously supplying the hydrolysed sludge to a reactor (25, 101) pressurised in line relative to the digester, before discharging said sludge from the reactor via a member (29) generating a pressure drop in the hydrolysed sludge, the initial stage being repeated at least once before supplying the, and/or via the, digester.

Abstract: Treating and conditioning liquid sludge and a solidified sludge cake obtained thereby are disclosed. A first emulsion of sludge is formed in an in-line container fed at a first flow rate Q owing to the impact of the sludge with air injected into the container at a rate Q′, where Q′>5Q, in a first region which has a small volume of less than 0.05 m3. The first emulsion is then transferred into a second region of the container extending over a first length, and is then discharged via a component which generates a head loss in a chamber extending over a second length. A flocculant is injected in order to obtain a second coagulated emulsion, which is at least partially degasified. The matter in suspension in the second emulsion obtained in this way is then filtered or decanted.
