Abstract:
The invention relates to a method for ultra-dehydrating thickened or pasty biomass products, in particular sludge from wastewater treatment plants, according to which the products, in particular products having a dryness of 4% to 25%, are subjected to the following steps: hydrothermal carbonisation treatment, including pressurization ( 1, 2 ) and thermal conditioning ( 30 ) for a duration in a closed reactor ( 4 ); followed by dehydration of the products by a ram press ( 12 ), obtaining a dryness of more than 50%; the temperature of the product upstream from the ram press dehydration being regulated by cooling between 40° C. and 90° C., advantageously to around 70° C., in order to optimise the filterability in the piston press; the steps of the method being performed in a confined space making it possible to prevent the release of smells into the atmosphere.

Claim (Index 1):
A method for ultra-dehydrating thickened or pasty products, forming a biomass, wherein the products are subjected to the following steps:\n hydrothermal carbonization treatment, comprising a pressurization and a thermal conditioning for a residence time in a closed reactor, followed by a decompression, then dehydration of the products by a ram press, obtaining a dryness of greater than 50%, the temperature of the product upstream of the dehydration by the ram press being regulated by cooling between 40\u00b0 C. and 90\u00b0 C. in order to optimize the filterability in the ram press, the steps of the method being carried out in a confined space that makes it possible to prevent the diffusion of odors into the atmosphere.
