Method and device for separation of suspended material from a fluid flow

摘要: ABSTRACT OF THE DISCLOSURE Suspended solid particles are separated from a fluid flow by dividing the into partial flows in channels having an upper filter surface travelling upstreams and lower downstreams, controlling velocity such that is turbu-lent but at same time low enough to allow for sedimenta-tion of suspended material form clear top layer off which more than half liquid fed channel filtered through surface, suctioning less sediment formed on finally removing surface.
