Supporting tubes (6) with aerators (5) are balanced against upward hydrostatic pressure by inside load. Each supporting tube is suspended on an independent float (8), which is floating on water-level by means of two pendant hoses (7).
The float with suspended supporting tubes and aerators are arranged into aerating lines. The floats are connected with each other and fixed to the air distribution with the help of a flexible hose (4). The aerating line is connected to the air distribution either from one side or from both sides. Air distribution, for each aerating line is provided with branches with spherical valves (3).
Air passes to the supporting tubes through this valve, the connecting hose (4), the inner space of floats (8) and the pendant hoses (7). The spherical valve serves to shut air off to individual aerating lines.

Each supporting tube is equipped with a mechanism to drain condensed water from the air. A small tube is led from the drainage cap (9), positioned at the upper side of the float (8), to the bottom part of the inner supporting tube). 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.
When the system is operating, water volume and the level around the float rises due to the presence of air bubbles in water.
Due to natural irregularity of distribution of bubbles, a difference in levels at the sides of the float occurs. This difference in levels forces the float to move towards the lower water level.
This takes places with floats in the entire aerator line, where the supporting tubes with aerators are made to float.
A limiting wire (2) serves to limit the sideways movement of the aerating lines.
The wire is fastened to all floats in the line and its ends are fixed to the opposite sides of the basin towards the (banks) braces (1).
After the aerator line reaches the edge, it swings behind the level of the standing float due to the momentum of supporting tubes and as a result the water level on the opposite side rises.
The floats in whole line start to move gradually back towards their second extreme position. The movement of aerating lines from one extreme position to the second is repeated all the time without mutual binding of individual lines.

The floating type is mainly intended to aerate natural purification and stabilisation basins of natural feature with irregular bottoms, ponds, dam basins, fish-ponds etc.
It can also fully be used in activation, sludge and other waste water treatment plants to ensure oxygen supply and adequate mixing.

The floating type can be used everywhere, where, due to the irregular shape and to the size of basin, the aerating system cannot be installed on the bottom. However it can be used in the classic and structurally modified basins.
Installing of the floating type aerator is executed into filled basins. Depth of immersion of the aerators is given by the length of pendant hoses.
Without stopping and pumping out basin, we can remove or re-install individual supporting tubes for checking or repairing purposes . After it is removed and reinstalled, it entirely preserves its original depth of immersion, provided the same length of pendant hoses is maintained. Removing is done manually from a boat
(2 operators).
Full-area aerating of tank and mixing of its contents is achieved due to the movement aeration lines between adjustable extreme positions.
