Three footings (9) to be used for each supporting tube with aerators (5) are anchored to the bottom of the tank.
Two rope strands (8) are led through the footings (9). Each rope strand is fixed to one adjustable support (7) of supporting tube, which is abutted to the bottom of the tank by the tube. The supporting tube is tightened to the bottom of the tank with the help of two rope strands. The guiding rope is pre-tensioned and both ends of its strands are fixed to the upper part of the tank with the help of a clamp (10).

Air distribution pipeline, against the axis of supporting tubes, is aligned by couplings with external thread and horizontal axis. Air is transferred to each supporting tube by means of spherical valve (3), disconnecting screw joint (2) and coupling hose (4). The spherical valve and disconnecting screw joint shut off air transfer and disconnect the coupling hose when supporting tube is removed from the tank.
Removal of supporting tube out of the tank is performed in the following way :
After releasing the fastening of the guiding rope in the fixture, the supporting tube floats up due to hydrostatic pressure. Then the supporting tube can easily be removed by hand. To reverse this procedure, the supporting tube should be placed on water level and pushed back to the bottom with the help of both ends of the strand. The strands are again fixed to the fixture.

Each supporting tube is equipped with a mechanism to drain condensed water from the air. A small tube is connected to the bottom of the supporting tube from the drainage cap (1) through the connecting tubing (4). After opening of drainage cap and with the system operating fully , internal air overpressure discharges the condensed water from the supporting tube above the water level.
The guided version ASEKO aeration system is intended for tanks accessible from one side (one sided installation) and for large tanks accessible from two sides (two sided installation).
Mounting is executed into empty tanks. The supporting tubes are levelled by adjustable supports. The flatness of the bottom is secured in this way and any possible surface irregularity is eliminated.

Removal and reassembling of individual supporting tubes for the purposes of checking or repair can be performed under full operation of the system without stopping the work or interruption of pumping.
The supporting tube preserves entirely its original level after it is removed and installed back to its original position. Removal is performed manually (2 operators) without any hoisting device.
