摘要

The device aerator for employment in the biological treatment of sewage.Which is intended to be used for the treatment of effluents from industrial or domestic, as indicated by the reference number (1) comprising an outer body (2) with a tubular configuration and has internally a concentric shaft (3), which comprises a stretch ext. Oar of greater diameter (4),A stretch of intermediary and tapered (5) and a smaller diameter opposite section (6), said passage end of greater diameter (4) corresponds to the region of the assembly of an axial inlet connection (7); the axial inlet connection (7) is defined by a concentric internal channel (8) which is to divide The between a first section (9) and a section (10), followed by aThe latter featuring a reduced diameter in comparison with the passage (9), the edge (11) of the axial inlet connection (7) incorporates, externally, a helical wall (12), a region (14) of the helical extreme wall (12) is held in perpendicular alignment with a Threaded opening (15), which is in turn a connection also threaded connection (16),That assumes a radial positioning with respect to the geometric axis longitudinal outer body (2) of the body (1).
