  • Apparatus for separating into its two phases a substance consisting of solid matter suspended in a liquid
    Patent number: 4966700
    Abstract: The apparatus comprises, among other things, an external group or unit (10) and an internal group or unit (20) which are movable relatively and which define a chamber (17) and an enclosure (223) separated by a body (11) permeable with respect to the liquid and impermeable with respect to the solid matter and an impervious elastic membrane (220) which can be expanded so as to be able to reduce the volume of the enclosure (223) in order to expel from it the liquid of the substance to be treated which has been placed therein and in order to press the solid matter against the body (11) or a filter (16) from where the said solid matter is detached by a scraper (50) so as to be collected separately.Application for the production of separated solid matter with a dry-matter content at leaet equal to 40%.
