Abstract
Föreliggande uppfinning hänför sig till ett förfarande för behandling av vätskeflöden på en cellulosafabrik, vilket förfarande innefattar åtminstone en alkalisk kokningsprocess för framställning av massa, en brunmassabehandling med väsentligen slutna vätskecirkulationer, ett massablekeri som använder ECF-blekning, ett sodahus innefattande en sodapanna för återvinning av kemikalier, och en avloppsvattenrening. Blekeriets kloridhaltiga avloppsvatten leds till avloppsvattenrening, där de behandlas för att reducera deras innehåll av organiska substanser. Minst 20 % av det renade avloppsvattnet leds tillbaka till cellulosafabrikens process och renat avloppsvatten används i ett sista tvättsteg som ingår i brunmassabehandlingen. Vätskeflödet vid brunmassabehandlingen drivs motströms till avdunstning, varifrån det leds till behandling i sodapannprocessen, där en avskiljningsprocess för klorider anordnats för att hålla lutcirkulationens kloridnivå under kontroll.
