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 5):
The method as claimed in  claim 1 , wherein the dehydration of the products by a ram press is carried out through flexible drains that form filters, which are permeable to the liquid that passes from the outside to the inside of the drains, whilst the solid materials are retained on the outside in order to be discharged by disassembling.
