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 6):
The method as claimed in  claim 1 , wherein the regulation of the temperature of the product upstream of the dehydration is carried out with the aid of a chiller heat exchanger.
