Flotators
Pressure flotators are one of the main facilities for the removal of hard-to-dissolve contaminants: petroleum products, oils and fats of animal and vegetable origin, heavy metals, surfactants, suspended solids, as well as for the separation of sludge mixture after biological purification.
They consist of a reception chamber, mixing chamber, flotation chamber, sediment zone and sediment and purified water bunkers. Equipped with a mechanical scraper conveyor placed on a frame structure with an electric gear motor mounted on it. The latter ensures the speed of movement of the scraper's working belt along the "mirror" of water no more than 10 mm / s.
To remove "heavy" fractions, the flotation device can be equipped with a screw pump mounted under the receiving chamber.

The principle of operation
The water enters the receiving chamber of the flotation device. After intensive turbulent mixing, the water enters the flotation chamber, in which, by reducing the pressure to atmospheric, dissolved air is released in the form of tiny (50-100 microns) bubbles and, in fact, the process of flotation of pollutants.
On the surface of the phase interface (water-air), colloidal particles of pollution are captured by air bubbles, their unification into larger clusters and removal to the surface in the sediment zone.

To increase the efficiency of work and prevent the flakes from slipping, the settling zone is equipped with a thin-layer module. The sediment formed in it accumulates in the hopper and is periodically pumped out by a slurry pump into a special container.
