Abstract: The invention relates to an arrangement for producing a flow in a wastewater treatment tank (1), comprising a substantially horizontal bottom (B) and a horizontal mixer (2, 3, 4), which is provided in the wastewater treatment tank (1) and which has a propeller (4) driven by means of a propeller shaft (3). According to the invention, in order to save energy to produce flows the axis (A) of the propeller shaft (3) is tilted relative to the bottom (B) by an angle α of 1 to 10° in such a way that a flow directed toward a surface (0) of the wastewater (W) can be produced by the horizontal mixer (2, 3, 4).

Abstract: The invention relates to a stirring device for activated sludges comprising a hyperboloid stirring body (1) attached to a shaft (2), wherein a plurality of transport ribs (3) are provided on the top (O) of the stirring body (1) running toward the circumferential boundary (UM) thereof, wherein the transport ribs (3) have an oblique course, at least in sections, relative to a radial direction, and wherein the oblique position of the transport ribs (3) is selected such that, when the stirring body (1) rotates in a predetermined rotational direction (R), a flow (S) is generated that is directed outward away from the circumferential boundary (UM) of the stirring body (1). In order to improve the efficiency of the stirring device, the invention proposes that a flow guidance device (7) for guiding the flow (S) generated by the stirring body (1) be provided in a plane running substantially perpendicular to the shaft (2), said flow guidance device surrounding the circumferential boundary (UM) of the stirring body (1) and being relatively fixed thereto.

Abstract: The invention relates to an agitating device, in which a hyperboloid agitating body (6) is connected to a drive mechanism (2, 3) by means of a shaft (4). Several ribs (7) running from the circumferential boundary (Ur) in the direction of the shaft (4) are provided on the upper side (O) of the agitating body (6). According to the invention, the efficiency of the agitating device may be improved, whereby a height (h1) of the ribs (7) at least incrementally increases from the circumferential boundary (Ur) of the agitating body (6) in the direction of the shaft (4).
