Sulzer submersible aerator XTA/XTAK
The submersible aerators XTA/XTAK are suitable for all gas-liquid reactions at temperatures below 70 °C and pressures below 2 bars absolute.
Applications in sewage and water treatment
Mixing and equalizing basins. Equalizing of wastewater pollution load and wastewater quantities, as well as avoidance of odor problems.
Activated sludge basins and SBR reactors. Biological degradation of organic substances.
Sludge stabilization. Avoidance of odor problems as well as further oxidation of the organic substances.
Flotation. Flotation of oil and grease. Lagoon aeration: Improvement of natural aeration.
Lagoon aeration. Improvement of natural aeration.
Neutralization. Neutralization of alkaline wastewater with CO2 or flue gas.
Special applications.
The submersible aerator is positioned on the bottom of the basin without anchorage. For maintenance and inspection work the aerator can be lifted by means of a mobile crane.
Construction
- Easy and quick installation without emptying the tank
- No aerosol effect and no sedimentation on the bottom of the basin
- Good oxygen transfer (SOTR) and aeration efficiency values (SAE)
- Self-cleaning system
- Replaceable wear parts
Operation principle
The submersible aerator XTA/XTAK is a submerged motor, blower, pump and mixer, all combined in one unit.
It consists of a star shaped impeller directly connected to the motor shaft, a stator surrounding the impeller as well as an air pipe to atmosphere. The impeller rotates inside the stator creating a vacuum and automatically aspirating air through the air pipe.
At the same time, water flows into the impeller, is thoroughly mixed with the air and radially discharged through the channels of the stator. This system ensures fine bubbles. XTAK = extended channels increase SOTR and SAE values up to 15- 20 %.
