Abstract

Framgangsmåte for fjerning av lost fosfat og fosfatholdig suspensjon fra fastQtoff-fattig avlopsvann. Avløpsvannet tilføres . fellings- og flokkuleringsmidler (henholdsvis 5 og 10) for omvandling av det loste fosfatet til lest form, og fellingsproduktene og suspensjonen (12) fjernes ved mikrofiltrering (13) med maskevidder i området fra omlag 10 til 150 mikrometer. Fortrinnsvis utføres mikrofiltreringen i to trinn (13a og 13b) som omfatter en forfiltrering (13a) med en maskevidde fra 60 til 150 mikrometer og en finfiltrering (13b) med en maskevidde fra 10 til 80 mikrometer. Denne framgangsmåten som omfatter bruk av mikrofiltrering har tidligere ikke vært ansett som egnet til formålet, og gir en betydelig reduksjon i innhold av faste stoffer og fosfor i avløpsvann.
