Presentation
The high-speed surface turbine ensures effluent oxygenation by drawing the liquid from the basin and projecting it into the air. The effluent is drawn in by the turbine propeller through the nozzle, then discharged into the air via the ejection cone.
When in contact with air, the projected effluent becomes enriched with oxygen. This mechanical action, which brings the effluent into contact with ambient air, also provides significant mixing within the biological basin.
Mounted on floats, the turbine is simply placed on the water surface, making installation easier and allowing it to adapt to water level variations.
It is suitable for civil engineering basins as well as lagoons, including applications with fluctuating water levels or shallow depths.
