Surface aerators
Aeration is a process in which the air is closely contacting with the water (liquid), by passing air bubbles through the water column, i.e. by direct contact of water and air/ oxygen. Aeration is used to saturate the water with oxygen in order to oxidize, for example, iron, or remove dissolved gases such as carbon dioxide or hydrogen sulfide from water. Aeration is the basis for the process of wastewater treatment in biological wastewater treatment plants (aeration tanks, air filters, biofilters).
- with elongated cone for deep reservoirs;
- with a short cone for shallow reservoirs with underside protection;
- trapezoidal suction device from the edges of the reservoir;
- with a rotating separator for better mixing;
- with overlappings to completely eliminate odors.
- treatment of domestic and industrial wastewater;
- aeration of tanks, reservoirs, ponds with variable level;
- intensification of biological treatment plants.
- low investment costs of the installation due to the lack of blowers and air distribution ducts;
- simple and reliable design made of stainless steel or composite materials;
- high rate of oxygen intake, especially for highly polluted industrial wastewater aeration in shallow air tanks;
- quick installation without emptying the tank;
- maintenance (lubrication of bearings) takes only a few hours per year.
