Abstract

Foreliggende oppfinnelse vedrører en fremgangsmåte for behandling av en fibersuspensjon slik at væskeinnholdet endres, hvor suspensjonen mates inn i et rotasjons- symetrisk fortrengningsrom (12) med en ytre avgrensende flate (4A) roterende rundt symmetriaksen, hvilken flate (4A) er gjennomtrengelig for fluider og er påvirket av et fluid under trykk fra utsiden.
