<p>The device for introducing gases in fluids in water in the sense of a pressure ventilation system having an air supply lines (1), comprises a hose line (2) secured under use of a tube clamp (3) on the air supply line, and an aerator (4) arranged near to the water base and connected with a weight (6). The hose line leads towards the vertical direction of the water base, at which a ventilation module is arranged. The air supply line is arranged in the area of the fluid surface and consists of floatable material. The weight prevents a lifting of the aerators. The device for introducing gases in fluids in water in the sense of a pressure ventilation system having an air supply line (1), comprises a hose line (2) secured at the air supply lines under use of a tube clamp (3), and an aerator (4) arranged near to the water base and connected with a weight (6). The hose line leads towards the vertical direction of the water base, at which a ventilation module is arranged. The air supply line is arranged in the area of the fluid surface and consists of floatable material. The weight prevents a lifting of the aerators, and horizontal and/or oscillated movements. The pressure ventilation is carried out as a system for the ventilation of sewage in aeration basin. The air supply lines are arranged longitudinally or diagonally to the longitudinal axis of the basin. The arrangement of the air supply line depends upon the size of the surfaces of the basin and the process technical demands of the sewage treatment. The weight is formed in the form of strand- or flat type and is presented by its center of gravity of an automatic erecting of the aerators.</p> |
