Abstract

Det beskrives en fremgangsmåte for behandling av avfall (D) ved tilsetning av en mengde av minst ett alkalisk reagens (R) som omfatter de trinn som består i å tilføre kontinuerlig avfallet som skal behandles, i en blander (1), tilsette konti- nuerlig til avfallet som skal behandles, en dosert mengde av minst ett alkalisk rea- gens, blande intimt og kontinuerlig i et gitt tidsrom avfallet og nevnte minst ene alkaliske reagens og, på samme tid, transportere den således oppnådde blanding gjennom blanderen, deretter tappe kontinuerlig denne blanding ut av blanderen, og det karakteristiske er at under blandetrinnet blir avfallet og et alkaliske reagens blandet suksessivt ved en første hastighet (V1), i en første oppholdstid (t1), og ved en annen hastighet (V2) som er lavere eller lik den første hastighet (V1), i en annen oppholdstid (t2) som ligger over tiden (t1).
