Jet Aerators transfer oxygen by simutaneously introducting large volumes of high kinetic energy liquid and air through a series of jet nozzles. The high velocity exits the inner, primary jet and rapidly mixes with the incoming air in the outer jet. This intense mixing and high degree of turbulence in the gas/liquid cloud travels outward from the jet along the basin floor prior to the vertical rise of the gas bubble column to the liquid surface.
Examples of applications where jet aerators are commonly applied:
Jet aeration technology is applicable across a wide range of wastewater and biosolids treatment applications including: Air Activated Sludge, SBR, MBR, MBBR, Oxidation Ditch, Aerated Stabilization Basins, Equalization Tanks, Aerobic Digesters and ATAD.
Oxygen Transfer Efficiency And Energy Savings In most industrial wastewater and biosolids applications jet aerators exhibit superior oxygen transfer efficiency compared to other aeration technologies. The hydrodynamic conditions within the jet and fine bubble cloud produces continuous surface renewal at the gas/liquid interface resulting in higher alpha factors. This results in superior process oxygen transfer performance in the presence of surfactants, extrecelluar enzymes and high MLS concentrations.
Process Flexibility Jet aerators are easily configured into any basin geometry including circular, retangular, looped reactors and sloped wall basins. Jet aerators are ideally suited for deep tank processes. The jet oxidation ditch is an example of technology innovation where the combination of a deeper basin design, bottom to top mixing and conservation of momentum combines to make a very efficient treatment process. In this and other applications the independent control of oxygen transfer and mixing is a valuable feature for both process control and energy savings.
