Abstract

Fremgangsmåte for behandling av slam hvor det slam som skal behandles føres til en blander (1) hvor det tilføres et eller flere alkaliske reaktivstoffer. Blandingen måles ved utløpet av blanderen (1) med hensyn til kohesjons verdi i slammet, og en dosering av en tilførsel av minst ett alkalisk reaktivstoff iverksettes for å få en gitt kohesjonsverdi eller et gitt tørrinnhold i slammet etter behandlingen.
