Abstract

Oppfinnelsen vedrører en fremgangsmåte for behandling av avløpsvann for å redusere innholdet deri av suspenderte materialer, spesielt parasitter, omfattende en dekanteringsfase bestående av å overføre vannet til en dekanterer ved en behandlingsrate som er større enn 10 m/t, hvori dekanteringsfasen etterfølges av en finsorteringsfase utført ved hjelp av en sil hvis maskevidde er i området fra omkring 5 mikrometer til omkring 25 mikrometer
