Abstract

Det er beskrevet en fremgangsmåte og anordning for å gjenvinne fibre som er anvendelige for papirfremstilling fra en utløpsstrøm innbefattende en primærprosess for behandling av en utløpsstrøm for å separere ut anvendelige fibre fra forurensende materiale, og sekundære operasjoner, som supplerer primærprosessen, for å behandle det forurensende materialet fra primærprosessen for å gjenvinne anvendelige fibre i rejektmaterialet. I tillegg separerer de sekundære prosesstrinnene rejektmaterialet i organiske og uorganiske fraksjoner som kan være anvendelige i andre prosesser. Fremgangsmåten i henhold til oppfinnelsen krever ikke tilsetning av vann slik konvensjonelle prosesser gjør, forenkler håndtering, deponering og reduserer depo- neringskostnadene.
