Aireators

Aeration is a fundamental operation for biological treatments of organic waste streams from industries and cities.The jet aerator uses the ejector principle to aspirate air. 


In operation, the motive water pressure go into by means of a centrifugal pump. Leaves the nozzle as a high velocity water jet. The jet entrainement action suck up the sourrounding air and acelerate it and mix them in a very turbulent zone, with generation of finely divided bubbles dispersed in the liquid. As a consequence, high mass transfer rate of the oxygen to the liquid occurs. 
The plume outgoing from the aereator inmerse in the liquid creates horizontal mixing streams that rise due to the low air/liquid density. At the boundary of the plume, velocity grandient create unstability and turbulence. This mixing action improves oxygen transfer and the solid suspension homogenety of the basin contents.
