Abstract (en)
[origin: WO2020136212A1] 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.
