Abstract

Det er beskrevet en fremgangsmåte ved behandling av et faststoffinneholdende material erholdt fra ef- fluent fra et industielt anlegg eller prosess, f. eks. et anlegg for avsverting av avfallspapir. Slik effluenc omfatter en vandig suspensjon av faststof- fer som omfatter organisk material og uorganisk partikulært material. Det uorganiske partikulære material inneholder en vesentlig mengde kalsium- karbonat og sannsynligvis også kaolin eller meta- kaolin. Faststoffene kan også inneholde karbonpar- tikler. Fremgangsmåten innbefatter at det fast- stoff inneholdende material underkastes en varmebehandlingsprosess slik at temperaturen er kontrollert til å være i området 600 - 800°C, for- trinnsvis 600 - 750°C, for å forårsake forbrenning av det organiske material uten dekomponering av mer enn omlag 50 vekt%, fortrinnsvis ikke mer enn 10 vekt% av det foreliggendee kalisumkarbonat for å fremstille et partikulært kalsiumkarbonatinne- holdende uorganisk material i hovedsak fri for organisk material. Det partikulære produkt er i hovedsak hvitt og anvendelig som et pigment eller et fyllstoffmaterial, f. eks. ved papirproduksjon.
