Abstract

Ved hjelp av hydrosykloner blir forholdsvis lette og tunge forurensninger separert fra en massesuspensjon. Ifølge oppfinnelsen blir først lette forurensnin- ger separert fra massesuspensjonen og massesuspensjonens fiberkonscntrasjon blir vesentlig øket ved hjelp av en første flerhydrosyklonenhet (6) omfattende et antall parallellkoplede hydrosykloner som er konstruert for separering av lette for- urensninger, og deretter blir tunge forurensninger separert fra massesuspensjo- nen med den økede fiberkonsentrasjon ved hjelp av en andre flerhydrosyklon- enhet (13) omfattende et antall parallellkoplede hydrosykloner som er konstruert for separering av tunge forurensninger.By means of hydrocyclones, relatively light and heavy pollutants are separated from a pulp suspension. According to the invention, first light impurities are separated from the pulp suspension and the pulp concentration of the pulp suspension is substantially increased by means of a first multi-hydrocyclone unit (6) comprising a plurality of parallel coupled hydrocyclones designed to separate light impurities and then heavy impurities are separated from the pulp suspension. - the increased fiber concentration by means of a second multi-hydrocyclone unit (13) comprising a number of parallel coupled hydrocyclones designed to separate heavy contaminants.
