Abstract:
    A method for flocculation treatment and separation of a raw fluid which is to be treated and which is charged with impurities in a suspension which are colloidal or dissolved, wherein the raw fluid to be treated is circulated with a flocculent reagent in a flocculation vat and the flocculated mixture is circulated in a separation area. The invention is characterized in that a central area is defined in the flocculation vat with the aid of a flow guiding tube, which is completely immersed, and a turbulent axial outflow of the mixture consisting of the raw fluid which is to be treated and the flocculent is caused in said central area (8); said outflow being angularly distributed (5), with the aid of a static device opposing the rotation of said outflow; the mixture is circulated in a peripheral area (3) and a fraction of said mixture moves towards the separation area.
