Abstract

En fremgangsmåte for fiokkulering og awanning av en vandig suspensjon av oppslemmede faststoffer omfattende at det i suspensjonen innføres. (a) en konsentrert polymeroppløsning, og. (b) en fortynnet polymeroppløsning,. kjennetegnet ved at de konsentrerte og fortynnede polymeroppløsninger innføres hovedsakelig samtidig inn i substratet. Foretrukket innføres de konsentrerte og fortynnede polymeroppløsninger i suspensjonen som en vandig blanding omfattende en fortynnet vandig oppløsning av polymer og en konsentrert oppløsning av polymer. Prosessen medfører forbedringer i filtrering og i filterkakefaststoffene.
