Abstract

Temaet for oppfinnelsen er en fremgangsmåte for å behandle vann ved flokkulering (4)/bunnfelling (5), som omfatter et steg (3) for å injisere en ballast og et steg (7) for å resirkulere nevnte ballast, kjennetegnet ved at den omfatter et steg (11) for kontinuerlig måling av konsentrasjonen av nevnte ballast og et steg for å sammenligne nevnte måling med referanseverdier. Tema for oppfinnelsen er også et vannbehandlingsanlegg for utførelse av fremgangsmåten.
