Abstract

Anlegg for vannbehandling ved flotasjon og omfattende en flotasjonsutrustning. Denne har en flotasjonscelle (10) for flokkulert råvann blandet med mikrobobler, frembrakt av et system (11) for trykksetting og frigjøring. Cellen (10) har en perforert opptaksinnretning (13) utformet slik at flotasjonscellens overflate kommer til å krysses av en jevn strøm av det vann som skal behandles. Oppfangingsmoduler (14, 15) er slik montert i flotasjonscellen (10) at deres nedre del får avstanden (h) fra innretningen (13), bestemt for å unngå forstyrrelse av den jevne fordeling av vannet.
