Abstract

En suspensjon tilføres et filtreringslag (1) bestående av granuløst filtermedium i et kontinuerlig virkende filter. Tilførselen skjer i den nedre del av laget (1), og suspensjonen tillates deretter å strømme oppover gjennom laget. Med den hensikt å optimalisere filterets kapasitet, styres suspensjonen nå inn i et sentralt område av laget. Suspensjonen blir i dette området delt i minst to bestemte proposjonale mengder, som hver ledes fra filtreringslaget (1) inn i ringformede mønstre med innbyrdes forskjellige høyder i forholdt til lagets utstrekning. Disse ring- formede mønstre har forskjellige diametre og hvert av dem er tilpasset forlengelsen av filtermediet i diameterretningen.
