    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: 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: 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.
