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>5q 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.
