Apparatus for purification of waste water or untreated (raw) water by a floculation method, comprising a container (1) having an inlet (2) for untreated water and an outlet (3) for floculated water, and having means (4) for stirring the water during its passage through the floculation container, and in which the floculation contaitner (1) contains partition walls (8, 9) forming concentric floculation chambers (10-12), and in which each partition wall (8, 9) and the wall (6) into the outlet (3) has passageway openings (13-15) for bringing the flow of water to pass successively inwards or outwards through the several floculations chambers (10-12) from the inlet (2) to the outlet (3), and in which a flexible or resilient deflection wall (16) is arranged in each floculation chamber adjacent the flow openings (13-15) thereof for directing the flow of water into the succeeding floculation chamber (11, 12) and for allowing a stirring means (19) to pass said deflection wall (16) in the floculation chamber (10-12). |
